Lapua Brass test - Loaded 19 rounds of Lapua Brass, full lentgh sized, used Sin clair mandrel to set neck tension. Powder h4350, bullet Berger 130 OTM. Control was my std hand loads with Hornady new brass, h4350 40g, Berger 130 OTM. All shot with Sig suppressor. Berger 5 shot rapid fire to foul barrel. 3 shot .56 at 100 yd.

Lapua results - 39 Gr .48 5 shot 100 yd, 39.5 5 shot 100 yd .58, 40 gr opened up as did the 40.5

Will try upping load to 41 and 41.5. The suppressor seems to have changed the node on the barrel. Will use Magneto Speed to verify FPS when I go next time.

All in all, happy with the Lapua brass.
