Well, Green Mountain finally had inventory on a 16.5" Fluted Blue barrel, so I ordered one up. I'll give up some speed, no doubt, but looking at reviews and tracking posts, it seemed a good balance of weight, accuracy, and price. It'll go into a Houge over-molded stock, the receiver is the silver finish, and the scope, a Nikon 2X-7X camo in Leupold rings should look cool and distinctive in the OD Hogue.

I'm hoping it shoots as well as my 77/22VBZ, as that will actually shoot into an inch at 100yds from a rest, with sorted ammo of decent quality. As Iowegen suggests, lot to lot variation is often an issue, but Federal HS, and Winchester Super X are usually a pretty good bet. The couple boxes of match ammo I've tried, not the mega-dollar stuff, have been mediocre.

One thought though. When the VBZ came home, it had several distinct rough spots when I was cleaning out the barrel, something I typically do with any brand new rifle. Several passes with a tight patch and JB cured most of that, and the rifle has been a tack driver since the first trip to the range. Because I can't leave a barrel fouled, I draw a couple patches through it using a section of 150lb test monofilament line every few trips.

Thanks for the inspiration,

TMan51, You're going to find your Green Mountain barrel will have a highly polished bore, unlike your Ruger 77/22. With a little powder solvent, your cleaning technique will work perfect. I never use a bore brush on polished bore ... it totally defeats the purpose. I would expect match grade ammo will work far better in the GM barrel than in your Ruger barrel. However due to the velocity loss and the vented action, I doubt if your 10/22 will get as good of accuracy at 100 yds as your 77/22.

When they were gone, I bought another brick (different lot number) only to find accuracy was mediocre. I have finally setteled on three brands .... CCI Mini-Mags for overall good performance, Federal Bulkpack for plinker loads, and Wolf Target Match for serious accuracy. I use the same ammo in my target pistols for the same reasons. If I were into competition shooting, I would probably stay with Wolf ... always excellent but also way more expensive.

ZommyGun, It's worth a try .... if cartridges have to struggle to chamber, no doubt the bullets are getting distorted. Only a good range test will prove or disprove how much it affects accuracy ... then the next lot number of the same brand may be different. I know for sure my little 22 LR die helps ... no more feeding problems and slightly tighter groups.

Here's a photo of my 22 LR die. The right end is the Go-No go and the left end is the bullet sizer. The punch is used to push cartridges out after they get sized.

LMAO... yeah... as soon as the teacher finds out the answers are on the net he changes the questions...

It's not FAIR... lol...

I was going to ask you today what length of barrel I would need to make a die like yours...was hoping it would be less than or equal to 2"...have an 18" factory barrel that I would not mind cutting to 16" but would not want to render useless forever under SBR...

So that part has been answered...

Next part is what do I need to do the chambering...and how easy or more to the point how much shop time would a gun smith need to make one for me if I gave him the barrel...I could have it cut...crowned for a usable 16" barrel and have him make the die out of the cut-off piece...

YES/NO...maybe...???

When I see some wolf I am going to buy it and try it...

For now I am going thru the cheaper/easier hv ammo hoping for a winner...once that is done I will go back to SV and see what I can accomplish with it...

I don't expect the 60gr bullets to work for me but I will try those too just in case I get lucky...

That will all take a while...planning ahead is required tho...

I will let you know what happens...

Later,
ZG

PS...based on your lot to lot variation comments I think I will invest in a 500pk of Vipers even tho they are not allowed for SBS...they are relatively low cost and unless they are a disaster they will get used...and if they are real, real accurate 500 won't be near enough...

Actually, I wouldn't bet a dime you're wrong.

I'm really looking forward to playing with some accuracy factors and the new barrel, but my VBZ has proven very accurate with decent ammo.

I'll cry if it dowsn't shoot better than my stock barrel, but that is a bad bet too.

I am sure it will be more accurate than the factory barrel and more accurate than mine...

I got mine because of the weight...it weighs only 14oz...factory barrel weighs 28oz...a steel bull barrel has to weigh a lot more...

The TacSol barrel is definitely chambered tighter than factory...that is for certain...

Additionally...I was not interested in having to have match ammo or be concerned about cycling...however...I have run into bulk ammo now that doesn't feed right...Blazer...not sure why...

I am extremely interested in finding the most accurate ammo for the barrel I have at 100m that is below hyper speed...

Still...

The Federal Game Shock was $7.50 for 100pk which is in the same price range as mini-mags...shot some at 100m and they seem pretty good...quality was good...didn't get the chance to do a good job of bench rest testing at a paper target but I think they are better than mini-mags in my barrel...possibly just as good as the super x 1435fps that is the most accurate so far but not allowed in SBS match...

If not for the SBS I really don't need to go out past 60 yards to have fun with it so therefore I wouldn't need the more expensive super x for anything anyway...

This whole ammo search thing is starting to piss me off...

Well, it can make you crazy.

Check out the sources that come up when you "Google" bulk ammo.

I am not a big fan of "bulk ammo" packed loose, but on average the carton/500rd boxes are often quite good. Over time I've had the best luck with Winchester > Federal > Remington. I never used a lot of CCI, but it has always been good stuff, but not as available "on the shel" for the shops I frequent.

You might want to try one of the Neil Jones guages. Sorting is fairly quick with practice, and works well in every case I've used it.

I am fed up with bulk ammo...it's okay for blasting a lot of rounds at short range but given the failure rate and lack of accuracy at long range it's really not much of a bargain for me anymore...


I currently have about 700 rounds of bulk I don't plan to use...that is enough...had good luck generally with Federal and Peters lubed 40gr...but not good enough...the goldens and blazers are a no go...

Although I am considering a 500pk of Vipers...probably not going to tho...if I was sure they would be on par with mini mags for feeding and cycling and going bang I would get them...

Mini-mags continue to be the all around go to for me...they were so with stock barrel and same holding true thusfar for the TacSol barrel...

It looks like the Game Shock is incredible close in price and reliability with at least as good and maybe better 100m accuracy for me...haven't gone thru enough of them yet to be sure...but since they are the same price as mini mags I am going to get more to find out...

Anyway...the bottom line is lowegan has put my mind to ease regarding feeling like I am missing something important getting better results at long range with High Vel and Hyper Vel ammo over SV/Target rounds...

Thanks old buddy...

ZommyGun, Based on several of your recent posts and threads, it looks to me like you are chasing your tail in a quest for long range accuracy. As I mentioned before, the slightest imperfection in the gun, sighting system, or ammo will start showing up at 60~75 yards and gets progressively worse as distance increases. 100 yards is a lot to ask of any 22 LR rifle, particularly a 10/22, but with the right combination of a barrel, scope, and ammo, decent 100 yard accuracy is possible.

Let's start with your rifle ... a 20" barrel is the minimum length for 100 yard performance .... longer is better. Your light weight 16" barrel is great for normal 22 LR shooting distances but lacks the essentials for long distances with high velocity ammo. The sole purpose of a heavy steel bull barrel is to dampen barrel harmonics. Your lightweight aluminum barrel won't do that, even though it is a .920 barrel, it takes considerable weight to keep it from oscillating.

Your VX-1 2-7x28mm Leupold is an excellent quality rimfire scope but was certainly not designed for long range shooting. According the Leupold's specs ... it is fixed parallax for 60 yards and has a magnification of 2.4~6.7X (magnification is commonly overstated by all manufacturers). That means your scope is about perfect for normal 22 LR shooting distances .... in this case, from 24~67 yards. That's where both magnification and especially parallax correction starts working against you. The lack of parallax correction alone can cause several inches of cross hair drift at 100 yards.

Last is ammo ... I'm not surprised that you get feeding malfunctions with cheaper ammo. I'm quite sure your TacSol barrel has a Bentz chamber ... if not, it is still much tighter than a standard Ruger chamber ... great for match grade ammo but too tight for cheaper grades ... especially bulk pack ammo where bullet diameters are too fat to chamber properly.

I really wish you the best with your 10/22 and hope you can find a solution. Sometimes you just have to compromise when you trade light weight for optimum performance. In my opinion, you have built a nice 10/22 for 50~60 yard accuracy but it lacks the features needed for 100 yard performance.

Yes you are 100% correct of course on the barrel...I knew that when I bought it...didn't expect it to be any better or worse than it is...

I didn't put the gun together for SBS or long range either...if those were my priorities I wouldn't have a 22 cal and wouldn't have an auto loader...

On the other hand...if the gun is decent enough accuracy...and light enough...and I am able to go shoot SBS with it...I am going to...therefore...I go out of my way at this point to conform to their rules with regard to gun/stock/ammo...

And of course...it only makes sense if one puts time/effort/money into any gun one likes a lot and wants to shoot a lot to do what is reasonable to get the right ammo and to tune the gun if possible for best results...that is what I am currently doing...

I get under 1" groups at 100 yards form a rest now...only problem is that ammo is banned from SBS...so I just have to go with whatever is the most accurate ammo that I can find AND am willing to pay for...both are getting more limited all the time...

As for the scope...please let that rest...

I have TWO scopes...one is a 40mm AO with a lot more zoom...

I get the EXACT same results at 100m with both...not just me...but two other shooters who are much better than me also...I get the same groups with both scopes and the same groups they got one with the 40mm and the other with the 28mm...

I will agree with you that if my goal was to make the smallest possible hole in paper at the longest distance possible from a rest that a big scope with A/O would be needed...

I'll get around to trying a few more types down the road...but for now...I went to Walmart ... and lucky for me they did have the 1600pk of 40gr mini mags in stock...

Mini-mags otherwise are completely sold out around here in both 36 and 40 gr...which is the only reason I bought the bulk pack...the price discount was negligible all things considered...

Got 300 more Federal Game Shok 40gr solids at the LGS...look forward to testing those from bench rest on paper at 100 yards...they really did impress me a lot the other day...but I was not shooting at paper and was out of mini mags...the best I could tell they were right on par with the super x only more reliable for going bang...

The Golden bullets suck eggs imo...

The Blazers I am not sure about...will give them another chance next time out...this is the ONLY round I have feeding problems with out of at least a dozen different ones including three other types of bulk...the Peters I have gone thru 800 rounds recently...feed fine...accuracy is no problem at 50 yards...don't always go bang...I would have bought more but they have been sold out for a while now and didn't get any more in this week...I am not going to miss them much now with my new supply of mini mags...

All others feed and cycle fine IF they go bang...price does not guarantee they go bang for me...the super x don't always fire...

Mini Mags it seems...ALWAYS go bang...

I was very aggravated with the Blazers but of course you just have to try them to find out right...

Anyways... MINI-MAGS are the new 'BULK' ...

So I can now say I have great results overall with 'BULK' ammo...

I find the Mini-mag velocitor works the best for me out of a stock barrel. CCI in general works better in my opinion.
