My gun groups better after a few 'fouling shots". After checking scope/bases/rings- Try the dirty barrel and then sell it if it doesn't improve. Good luck.
One of my XCRs will do that. The sweet spot is between rounds 20-50/60ish depending on temperatures. It'll come down to cloverleaf then start opening up again.Killshot, what size groups are you looking for? I've never seen a gun shot that bad tighten way up (i.e. under an inch) unless there was a mechanical issue like a bedding problem or loose screws. Sometimes I think it's better to cut bait (after the usual checks). I bought a new 7mm last year myself and none of my groups even with me behind the scope we're that bad so I'm wondering also if you got a lemon.
2920 fps out of a 23" barrel (gun had a BOSS that I cut off and had barrel recrowned so barrel is abnormal length)Grizz
What's your barrel length and muzzle speed?
I too shoot the 150 Corelokt's with great accuracy and success in my 7 RM.I've been using plain old Core-lokt 150 grain ammo in my 7 RM for over 35 years on deer and antelope and have never had any reason to try anything else.
If your rifle particular rifle shoots them well they are hard to beat. As a plus they are very easy to find most anywhere and are relatively cheap compared to other factory ammo loaded with premium bullets.
What kind of scope did you use and how many M.O.A. angle bases did you have on your factory Winchester rifle to shoot it to 1 mile? Just curious.These are 168gr Berger Classic Hunter with 58.3gr IMR 4350. 300 yard group.
