Planetcat Posted June 9, 2019 Share Posted June 9, 2019 I know this is a long shot shot on this deader-than-dead forum, but I can’t get my .338 wm R1 to get decent groups (<1” at 50 yards) with 210 gr. Barnes, .225 gr. Federeal trophy copper, or 185 gr. Hornady gmx. All three shoot radically different groups - all mediocre. I had my barrel cryo treated again at 300 below, and it seems to allow me to shoot about 10 shots now before the barrel heat affects accuracy as opposed to 3-4 shots with factory barrel. Thats not the issue though, I just cant get decent groups with any non-lead ammo that I can find regularly. Buffalo bore makes 250 gr barnes, but that is a lot of bullet for hogs, deer, and black bear. Plus its expensive! I’m at a quandary. Any other suggestions? I dont reload. Also, my stupid restrictive state says i have to hunt with non lead ammo. 200 gr sst’s shoot great out of it. Her’s a picture of a nice sow I shot a few months ago with 200 grain SST ammo. She was drt at 150 yards. Quote Link to comment Share on other sites More sharing options...
Thunder90 Posted June 13, 2019 Share Posted June 13, 2019 (edited) Hey planetcat, I have had similar issues with my 300wsm. It did not like copper bullets (at all) and only gets mediocre groups with premium non-monolithic factory ammo. What kinda groups u getting with SSTs? Nice sow!

I’ve found that my rifles made in Europe don’t like the non-lead bullets. Three R1’s(.30-06, .300wm, .338) browning bar .308, and winchester .308 and .338wm made by FN. All have mediocre and/or inconsistent groups using barnes, trophy copper, and gmx ammo. I bet if I reloaded, i could dial them in. I’m getting sub 1” at 100 yards using .338 wm 200 grain superformance sst’s. The .30-06 and .300 wm R1 are over 12 years old and I get very good results with 180 grain bullets (Hornady interbond, federal blue box soft points, and fusions).
