300 SAUM Imp

@tom I’ll give you some 220gr LR Hybrids if you wanna run a ladder with them as well...

They have the same BC as the 230 but more consistent tipped meplats.
 
Gonna wipe the dust off mine and get back to work on my bullets soon.....hopefully I'll have something for @GlennK this year! Lol

Tom
 
Well it definitely warmed back up for you. Might have to wipe the dust off the lawn mower too if it gets any warmer. Lol

Are you trimming the meplats on the Bergers? I found it helps a little on the 230s.
 
It's 4350, a lot I hadn't tried before, but I did hit what I was targeting for velocities.......not that it mattered though.

Tom
Did you run CCI250’s, Tom? I’ve had much better luck with BR2’s in that size case. Looking at the target, a primer change may be the ticket.

These were br2s today, as I go through notes i think fed 210s made it happier with 4350. At one point I was getting somewhere with 4350/210s and a 207.2 version of this bullet. My thought was to try lighter next go around and now is the next go around lol. I tried br2s on an educated guess, and possibly was wrong.......if it was a 6mm I wouldn't ever be wrong!!! Lol, except when I am.

Maybe I’ll try that. I’ve been running 215M with 4350 and 200.20x
