Does this seem hot for caliber?

[Hammer101st]

6.5x55Ai 150gr Smk

I did all the measuring and visual case inspectins i could think of and every thing seems fine.
I want to use 4831sc since i have 2 kegs and dont want to use up 2 most favorite powders. I dont think ill get the speed before pressureing out with H4831sc.

I had a couple guys tell me these speeds were to hot but then i had another guy show me he was gettin 2950 to 3000 with the 150grn and 4831sc i didnt get inspect his brass he could of been junkin it for all know. Im fine with 2850fps but i want use 4831 since i have so much of it.

What do you guys think?

What rifle are you shooting it in? Not sure I'd push it much in an original surplus.

Its in a trued savage action

Then I'd just consider bolt lift, primer and dia at the .200 line to see if it is approaching pressure limits. Maybe run a GRT or Quickload simulation on it.

Measuring at the 200 line is the only safety I have don't have grt or quick load

How long is the barrel? Those speeds tend to be hard on the brass. Primer pockets open up fast even with Lapua. I shot a lot of RL23 in the X55AI. I also had 150SMK’s blow up around 2950. Nice cartridge in theory but even Lapua brass is a bit soft in my experience.

I think the barrel finished out at 29inch's. Yea im happy with 2850fps i just dont want to use up all my RL23 or 7828ssc thems my 2 fav's. I have 2 kegs of h4831 that i dont use in anything else. Im gonna start in on that powder see were it takes me.

I think you’ll do fine at 2850 with H4831
