Muzzle blast doesnt seem like a problem when I shoot my .338 RCM. To me, it is a combination of both shorter OAL and balance. My son's Model 7 SAUM just FELT better in my hands than a standard length action.
Of course, the RCM is several inches shorter which really adds to the appeal.
Are the three shots that are within .5" the first three? With that thin barrel with a .264 I would expect it to start walking around a bit after 3 shots. For a hunting rifle I only use three shot strings since that is pretty much all I will get in the field.
I know...I'm a little late to this thread...but I just cant see how a 20 inch carbine with, at the very minmum, ballistics equal to a hot loaded .338-06 could be a bad thing. The more I hunt the more I enjoy lighter and more compact rifles. I love my .338 RCM. It HUNTS better than my 30-06 and...
I am doing some testing with 2520 and 180 Noslers, 225 hornadys, and 250 Sierras. Due to the weather I havent shot any of them yet. I've only gotten mediocre results with factory 200's so far.
