what's your coal

mine is pretty heavily compressed at 73.5 (Winchester brass)
and I'm seeing mild pressure signs not enough to bother me for a low-volume hunting rifle
don't ask me what that is off the top of my head

I was wondering because I'm pretty sure another 0.7gn would be very warm in my rifle

3.425 coal. Is getting up there in pressure. I might dial it back once I've used a few loadings. However it doesn't get alot of use as is a hunting rifle

How did you get on with a load ? Interested to see what you settled on.

I shortened mine to 20 inch not long after I got it.
I used Vihtavouri N160 62.5 gn and a Sierra 160 game king.only doing 2753f/s .
At the time it was what was available so I stuck with it and it filled the freezer. Have a box of sierra 165 gr TGK #4565 that I’ve been meaning to try and some different powder choice.

What primer are you guys using for these loads. I was using a CCI 200 primer cause that's all i could get at the time, but recently tried some federal 215s with the same load and got an extra 50fps and very consistent speeds , 3000fps from 22 inch barrel but think its right on the cusp of a bit hot!

I chopped my 7mag laminated stock T3 to 22” when i added the dpt on the end have a zeiss 3-15 too!

Back then 2020 I been using N560 for several years after reading positive recommendation from Tracey Short (Dead Eye Dick) looking up my notes the last load I recorded was 162 Amax with 72.0 gn n560 norma brass fed 215s. 3 shots went 3044/3086/3079.

Rebarrelled to 7Saum 20” in 2021.
