6.5prc coal

[Flyjunky]

I’m wondering if someone might be able to answer if a mag length of 3.1” is long enough to seat either the 156 Berger or 147 eldm at the neck/shoulder junction? I don’t have any 6.5prc brass to measure it myself.

GRT says the 147ELDM would be at the neck/shoulder junction at 3.08", the berger isn't in their bullet database to check.

Thank you

Maybe slightly deeper. Puts me 25 thou off in a Sammi spec chamber. Berger 156

Thank you, seems I’ll be ok at 3.1”

Unless you do a really long freebore you will be fine

The coal is all gonna depend if your at the lands, off the lands, or jamming. In 3 different custom 65prc barrels, saami reamer, a 156 is 3.083 +-4 thou for bullet nose length variance, same bullet used.

A 147 has a lot shorter nose and will likely be around 3.000 touching lands.

Are you creating dummy rounds for custom throating?

A 3.1000 mag will handle a 156 seated to the lands in a saami spec chamber. Typically that bullet shoots great 25 to 30 off the lands, and you'll be around 3.060-3.050 coal.

I’m looking at getting a ph3 in 6creed for my daughter. I was just curious for options down the road if I wanted to go 6.5prc and their mags will accept up to 3.1”.

The seekins short action prc with the 3.100 carbon mag is about the best setup out there from a non-custom viewpoint. They did their homework on that.
