Re: WEATHERBY ACCUMARK V 338/378- WHAT ACCURACY TO EXPECT ?
The 338-378 accumark is as good a long range hunting rifle as you can get. All I have ever seen come through the shop would have no problem taking game at a half mile with minor work you would do with any new factory rifle. Velocity with a 26" barrel would average about 100 fps faster than a 30" 338-300 ultramag. You would also have the best platform available for a rebarrel job at some later date if you wanted. A $400 barrel from pac-nor would be awesome on the accumark.
If you have a magnum action or can get one fairly cheap then a 338-300 ultramag barrel from pac-nor and you will have a very good long range rifle. Back in the 90's I did around seventy five 338-300 ultramags with pac-nor barrels and they all shot extremely well. Pac-nor quality is among the best. You can get a headspace guage from midway and you are in business. Screw it in, headspace and bed it the way you like and it will be a very good rifle. The plus of the 338-300 ultramag is it can get you into the low end of the big 338 chamberings with very little expense to build and then to shoot with cheap brass. No way I would ever consider paying custom money for this chambering though. Just to many better choices that beat the pants off it.
Predictions are difficult, especially when they involve the future
