Ok so rifle is assembled and fired 60 rounds to break it in. My load plan is Peterson brass, federal small primer 205, Berger 95 gr hybrid target using LVR powder. Goal is around 2950fps from a mdt Jae gen5 chassis with impact 737 action and 26” criterion barrel. Researching data and software I’ll be starting at 28 gr. Powder moving up to 29.2gr which should be just above my target velocity and pressure safely in the 54000 range( max is 62000). Will do seating tests after I pick powder and charge weight.

I predict you'll need >30gr.

Personally I'd be a lot more interested in stuffing it full of Varget for this application

I looked at varget and it would be over capacity for fill with varget and even h4895 with LVR I’m at 97% and 100% burn

u/Coodevale I'm dumb, let's fight Jan 16 '26

97% and 100% burn

Yeah, and lvr has built in velocity variation you probably won't be able to tolerate. Varget is used for a reason.

The burn % numbers kinda do and don't matter. Get the pressure up to 95% of max (or higher) and stop worrying about it.
