.22 LR, 36 or 40 grain? accuracy...

I am asking which will be more accurate when fired from my mark iv?

my primary experience has been with my colt 45, acp...
a 185gr round fires more accurately than a 230gr, faster and straighter...

is it the same way with 22LR?

no, it's not.
my 22/45, mark 3 will do a 7/8'' group at 25 yards using wolf, 40 gr.
that's benched, of course, but that's a match grade gun shooting match grade ammo.

You're just going to have to buy a few boxes of different ammo and see. My standard likes cci mini mag. I also prefer copper plated bullets, to minimize my exposure to the lead

Agreed. With rimfire guns, each one is different. The only way to know which ammo shoots best in your gun is to try different kinds.

It depends entirely on your gun. You might get lucky or you might have to find the ammo your 22 likes, both for accuracy and reliable function.

OP...that's the fun part. Buy a few boxes and test away. My 22/45 Lite shows no real diff between bulk ammo and higher end stuff.

I've only fired 100 rounds through it last week, so far... using aguila high velocity 40-gr, copper coated... and intend to get some cci mini-mags, 40-gr copper's next... (and probably will only use only the copper coated, because I think it's cleaner)

35 ish years ago when I got my nylon 66, I thought all 22 LR was all the same, until I bought some yello-jackets?... bunch of flyers... (I may still have a box of those sittin' around, left over? gonna see if the box has a grain weight, printed?) hated 'em...

I can appreciate trying different of course, to see what works best...
but I thought there would be a "bench mark" difference between 36-gr vs. 40-gr (same manufacturer), that others may have experienced?

the big difference i'm aware of is between sv n hv.
all match ammo is sv
most people find sv the most accurate in most guns.

test cci sv.
it seems to work well in most guns.

I've never found anything that my .22 didn't like. Had some really old ammo once that could hardly make it out of the barrel, but it still digested them. When you're out plinking, any ammo will do.

sure, if you can load it? it will/should go bang...

I guess it was just my silly question time...

as far as jamming goes, trial and error is the only way to know.

as far as the SV vs. HV? the sv's are lead nose... and i'll probably stick to the copper coated. but thanks, for that...

I was looking around on the cci site, and the aguila site as well. and other rimfire forums for answers.

I did find out that generally the lighter 36-gr's are a hollow point... the actual weight difference in the bullet is only part of the mix... the actual velocities are also a bit slower because of less powder in the casing... go figure? who knows why?

there are also some nickel casings available... with reduced friction in feeding, I might try some, if I can find?

but I guess it still comes down to... try it, I might like it...
and, thanks for the inputs.

yrffej, After you get enough posts, you can access the Forum Library where I posted an article that specifically covers your concerns. The document is titled "22 Long Rifle Accuracy". Here's a link: http://rugerforum.net/library/106039...-accuracy.html

interesting read, io.
where does premium end n match start.?
tons of poor ammo calls itself match,
i have to tell you, my experience differs from yours.
perhaps i lucked out on my 22/45. i do think of it as match grade.
with cci sv, it will give me a 1 1/8'' group at 25 yards, but wolf gives me a 7/8'' group.
that's benched of course, on my rain barrel.

susieqz, All "true" match grade 22 LR ammo uses 40gr bullets and develop a velocity of 1030~1085 fps. All match grade ammo is considered "premium" and usually the price reflects that. Some premium grade ammo is High Velocity .... could be a 36gr @ 1280 fps or 40 gr @ 1255 fps. Some other premium grade ammo is Hyper Velocity with bullets as light as 22gr and velocities as fast as 1640 fps.

Most bulk grade is High Velocity .... either solid or hollow point in the same velocity standards as above. The difference is .... bulk grade ammo is not as tightly controlled for priming compound, powder charge, and bullet weight or diameter plus it packaged with "loose cartridges" in a large capacity box rather than stacked boxes of 50 or 100 rounds. I call bulk ammo "pre-damaged".

Just a word to the wise .... just because ammo is rated as "Match Grade", it doesn't mean it will be more accurate than Premium grade ammo or even Bulk Grade ammo in a specific gun. Fact is, with 22 LR ammo, there are so many exceptions to the rule that you just can't make a statement about accuracy and have it be true for all guns or brands/types of ammo.

By definition, "match grade" means the handgun and ammo combination must be capable of shooting sub-inch groups at 25 yards (4 MOA). For match grade rifles, it's sub-inch groups at 100 yards (1 MOA). There are many gun and ammo combinations that will meet this criteria even with non-match grade guns or with non-match grade ammo. That said, when you get a truly match grade pistol such as my S&W Mod 41 and shoot Wolf truly match grade ammo, it is not unusual to get 1/4" groups at 25 yards from a bench rest. I can typically outshoot most 10/22 rifles at 50 yards with my Mod 41. Of course I cheat a little and have a 2X Swift scope mounted on my 7" barrel. My "Slab Side" Ruger MK III (6 7/8" barrel) also prefers Wolf match grade ammo and will shoot as good as 1/2" at 25 yards. It also has a 2X scope.

For rifles .... my 10/22 build with a 20" Green Mountain bull barrel and Wolf match grade ammo will shoot tiny groups however, at 100 yards, it takes a good day with no wind to break the 1" group barrier. My CZ 452-2E bolt action rifle (24 3/4" barrel) is not considered a match grade rifle, however it will shoot sub-MOA groups at 100 yards with most any high velocity 22 LR ammo. On calm days, I have shot 1/2" groups many times.

I guess the point is .... try several types of ammo in your gun and choose the one that groups and functions the best. Once you have established the optimum brand/type for one 22 LR gun, DO NOT assume that same brand/type will shoot and cycle the best in another 22 LR gun. I own many 22 rifles, pistols, and revolvers. Sometimes the best ammo performer in one gun is the worst in another. Further, even with like brands and models of guns, it doesn't mean the same brand/type of ammo will be equally accurate in all of them.
