I can reach 3100' with 190 grainers in a 28" barrel. You could expect to max out around 2950' with a 24". The case is a 300 Sherman and is compared to a .270 case in the pic.......RichAttachment 18013
I wish I these had been available when I built my .30-06AI some 8 years ago. However, my velocities are not too far behind what you are doing and right now it wouldn't make much sense to switch over.
I'm getting an honest and safe 3125 FPS from a 168g Berger VLD and 2915 FPS from a 190g VLD Using H4350. ( With a 26" bbl) Both bullets shoot one holers and are great Elk and Muley Medicine. So far I've taken Elk out to 550yds with no problems.
I love the concept and I can sure understand your excitement....
I'll watch this thead for more updates!
