Had a chance to run these through the Mashburn this weekend at 3225'ish. Pretty accurate bullet for me in this rifle as well.















Overall, a very impressive bullet in my opinion.
 
Very impressive. I do like the A-Frames a lot in my fast cartridges.
 
Looks good. That would put the smack on everything from mice to moose.

Can not wait for the 154 test this weekend Scott!

I'll have it tee'd up for you Fotis. Heck, for deer hunting I wouldn't mind giving it a shot. It shoots very well with the same load I use for the 160 ABs. It would have to be decisive at 3250!
 
When I toured the Swift facility back in the 90's they were still using a small plug to close the hole in the Partition. When firing .338 cals into test media, this plug could be seen protruding into the core, signaling a weakness in the Partition.
To your knowledge, has this design been remedied? The media I used was a silty/loam as described by Bob Hagel. I realize that such media is tougher on bullet design. It does however seem to reflect what happens when bone is encountered in my experience.
 
No idea but every A-Frame has looked the same to me. Great Bullets.
