My friend and I both bought Savage Axis .308s. My Buddy bought some Remimgton 150 grains and I bought some Remington 180s. I thought that havering a 9.5 twist that the heavier bullet would be more stable. We both sit down and preceded to go through the BORING barrel breaking in by Savage instructions. Anyways when all was sails and do e my buddies 150s were grouping pretty nice and my 180s were all over the paper. Is the 180s too heavy for that rifle? I now know that Savage recommends 168 for best results and when I start reloading all this brass I will go to Hornady 168 Z Max unless told different .
MontanaMarine shoots them 215 Berger VLDs in 1:12" out of his .308 Win, granted it's a custom load and have the altitude on his side, but just want to point out that the bullet weight and twist rate noted shouldn't be a factor.
Handloads are developed and customized for a particular rifle. I have 3 .300 Win Mags (one of which is a Savage) and none of them have the same load. Having said that, your rifle probably just doesn't like that particular load (as noted above), that will change when you start hand loading.
You have gotten pretty good recommendations, but please take no offense but make sure it's not the nut behind the trigger that's causing the challenge on hand.

In the early 1990s while at Tucson Rod and Gun Club range, I fired 3 rounds each from of my 3 rifle and have to wait until the range is cleared and safe to retrieve my targets.
While waiting, I was admiring the set-up of the shooter to my right; a beautiful Blaser rifle in .30-06 topped with S&B. He was shooting factory ammo and was very frustrated as he was adjusting his scope often.
He asked if I can help and I gladly obliged. I fired 3 shots; I was 2" high and 2" right from his last POI but was well within 1 MOA at 100 yards. He fired 3 more shots and it was even worst than his last shot. However, I did noticed he was jerking the trigger and anticipating the recoil ... also closes his eyes in doing so.
Come to find out, he had shot 3 boxes of ammo already and the best I can advise him at the time was go home and come back another time. Unfortunately, that was the last time I ever saw him at the range. In this case, it was clearly the nut behind the trigger.lightbulb
Good luck and happy safe shooting/hunting. Cheers!
