6.5 grendel sbr powder. Choices

[LRRPF52]

Published data works fine for 12” and 24” Grendels.

The powder is fully converted within the chamber + 1.5-3” ahead of it, especially with a short fat case like Grendel with a 30 degree shoulder.

The spark shoots into the powder column nicely with Grendel, unlike legacy cartridges such as .30-06, .270 Win, .280 Rem, .300 Win Mag, etc.

You’ll notice this dominant trend in the rifle cartridges developed over the past 2 decades, like WSM, WSSM, SAUM, 6.5 Creedmoor, 6.5 SAUM GAP 4S, 6.5 PRC, 300 Norma, etc.

For 12” Grendels, one hand load that works really nicely for target-shooting is the 107gr SMK on top of 8208 XBR.

I was just shooting factory 123gr ELD-M yesterday out to 800yds, working the steel from 200-on-out, and I was just hitting target after target like it was easy or something.

Hornady uses a canister powder for their factory Grendel ammo, so it’s hard to duplicate that load.

My buddy’s 12” Grendel I built for him using the same core components as mine really likes that 107gr SMK/8208 load, at 2450fps.
