Back in the day many of us would take a factory gun into our smith and have them tune the trigger and lap the barrel. A good factory out of the box group was about 2" at 100yds but the lap job and stoning the trigger would bring it under an inch.
Barrel making has been the greatest improvement in technology and machining in gun manufacturing in the last 40 years. That and the much better quality bullets of today are why we expect 1/2" groups @ 100 yards from our rifles as a matter of course these days. You young punks just don't know....
In developing a Berger 210 load for the 300 WinMag I have found most of the 300 WinMag fraternity among the members here are getting >2900 fps. So Mudrunner's buddy is not pushing his 185 at all.
Let me restate my position: 300 WinMag all the way if you can handle the recoil. My youngest son and I regularly pound 50 rounds of magnum ammo off the bench and are no worse the wear - without muzzle brakes. You can develop the ability to handle the recoil one step at a time. But if you cannot handle it right now my suggestion is to use a 7mm Remmy. And EVERYBODY should be reloading!!!
+1 on hand lapping I have also seen 2in. Rifles go to 1/2in. I never rule out a inaccurate rifle till trgger work and hand lapping is done. They foul less and clean easier. I personally seen a savage axis 308 go from 2in. After extensive load testing, then lap the barrel and trigger work, it went to 1/2in. average with very little load work up.
