I've been wanting to try some of the different loads in rifles with MMP sub bases. On the last order we finally got our supply so we are set. TodayI took the Renegade rifle out. On it was barrel #2 (I have two of them both the same caliber) Stainless Steel Green Mountain Barrel. This rifle normally shoots the .458 300 grain Hornady HP's real well so I put a sub base under them and the accuracy was not what I expected at all. The first shotI contributed to a clean barrel but normally that should have been in the center of the bull. When the second only climbed a short distance, I decided to stop and test a different projectile.

With the sub base I figured I could increase the powder charge a little so I pushed the 250 grain Shockwave up to 110 grains. The rifle shot as if I had a modified hold instead of an open 6 o'clock hold which accounted for the lower hits. I wonder if that was the case for the 300 grain Hornady HP's as well. Once I started aiming with a modified hold the rifle actually did very well. The sabots looked almost new other then some rifling marks on them.

A real interesting test actually. I have other bullets I want to try with the sub base and now that I have some pellets, I want to see what the Black Diamond XR will do with pellets and some of the projectiles and sub bases...

Others who have shot sub bases.. did you notice a large difference in the POI of the rifles and projectiles you tried?

I was going to keep paper punching but noticed a large number of tree rats, a.k.a. pine squirrels, in the lower part of the woods, so I went out to thin the herd. I was disappointed. I only got one. But the 250 grain Shockwave with 110 grains of Pyrodex was able to knock him off his feet (and then some). for those curious, no problem with knock down on him...
