Factory loads RAR .30-06 all-weather model?

My son's Ruger American left-handed all weather refuses to group well for us at 50 yards. Clean or dirty on a cold barrel with 165 grain or 150 grain hornady, fusion, and federal soft points, we are getting 3-4" groups. Ive Mentioned before that when the barrel is hot (5+ successive shots), it sprays all over. So we let it cool between shots. Three of us shot the rifle today with similar results. What factory ammo and bullet weight are you RAR .30-06 owners seeing best groups at? Barrel is not touching the stock, trigger is probably a little over three pounds, and scope is tight. Rifle is almost two years old. Thanks in advance.

Try Remington Corelokt I would try 180 grain to see if your gun likes that. The American is really a crap shoot in the bigger calibers. Make sure the action screws are snug.

Everythings tight on the gun. I just picked up a box of 180 grain core-lokts and some federal blue box 180's. I will bring them to the range next time and some barnes copper, just to mix it up. If we cant get it to at least get the groups under 1" at 50 yards with any if those, it goes on consignment.

My Ruger American .30-06 seems to like Remington Core Lock 150 grain best, though it is not the all weather version, it is the plain Jane model. This is a 5 round "group" that I made when sighting in my scope (Nikon 2-7x32) at 90 yards. The hole in the upper right was the first shot. The three close together were the result of me aiming at the first hole and firing to see where the rounds were actually going. The one to the upper left was my error. I have not tried any other rounds for grouping specifially, but so far those three are the best and I was using 150 grain Remington core lock.

Try Federal Fusion.

Seriously, I don't think this as an ammo issue. The most inconsistent cheap ammo should still be inside an inch at 50 yards.

I agree. Shooting that poorly means there is an issue with the rifle/bases/rings/scope. I'd pull everything off to double check. Swap out the scope for a known performer and try again. There is something going on more than being finicky about ammo. I had a muzzle-loading rifle that wouldn't group no matter what sabot or Power Belt I tried. I finally swapped scopes and realized recoil had broken the old one and zero shifted with every shot.

You guys are awesome. The scope is an inexpensive Bushnell Trophy XLT that came off one of my other rifles. I have a backup scope that is brand new in box that I will put on there, re-bore sight it, but also try the CoreLokt 150's. I also have the Federal classics and other CoreLokts in 180 grain that I'll try. If these group well with the new scope, I will shoot the ammo I shot last weekend to see if it groups better too. That will pinpoint the scope as the culprit. Oh the joy of finicky rifles.

So we took the RAR .30-06 left handed rifle to the range today with a selection of ammo. I did three things, based on info here. 1. I put a new scope on, 2. I loosened the screws a bit that holds the action to the stock, and 3. Tried different ammo. I had torqued the heck out of the bottom action screws, and read somewhere here that loosening them fixed an accuracy issue with someones m77. I just backed them off a half turn so they werent potentially binding the action. I shot federal blue box 180's and 150's, as well as 180 grain core-lokts. All three ammo shot overlapping cloverleafs at 50 yards. Plus, we shot about ten shots in succession without the usual hot barrel stringing.

I wish i knew which change fixed the problem, but my son is very happy with the accuracy now and can hunt with it confidently. It went from a mediocre rifle, to a near tack driver. Very happy and thanks for all the advice.

Planetcat, I know this will sound strange but try sighting in at 100 yards and your groups will likely shrink. At 50 yards, the bullet is still in its centrifugal force spiral and heavier (longer) bullets will just make it worse. Read the article I posted in the Forum Library titled "Internal and External Ballistics". Here's a link:

^That's a very interesting article. A good read. Next range trip, we'll hit the 100 yards and see how that works out. I've had some very finicky rifles, but the variation in accuracy on this RAR between loads has been eye opening. I still think it was either the scope or the overtightened action bolts.

The one thing interesting about your article, is the relationship between rifle twist and bullet weight/size. I always thought you needed more twist rate to stabilize heavier bullets, but your write up says opposite. I have to agree with you on that point, as I noticed on my 1:12 twist rifles (browning, winchester) shoot 180 grain .30 cal bullets much better than 150 grain.

I would love to see a slow motion, time lapsed video, of a bullet with a mark on it to count the revolutions over time and distance.

My vote goes to a bad scope.

I would snug up those action screws again before shooting also.

Probably was the scope.

The more I think about it, the more I tend to also think it was the scope. I guess I was in denial, since I've mounted and shot dozens of scopes without issue. And thinking back on it, the "bad" scope on the RAR came off another rifle, which had inconsistent accuracy issues too. Not as bad as I had recently, but the scope probably got worse over time. What a POS. I think that's my last Bushnell scope.

Also, the action screws are sufficiently snug, but not over torqued as I had them previously.
