RL15.5 in 6BR?

[fatelvis]

Is anybody having good luck with RL15.5 powder in the 6BR? If so, please share your load! Thanks.

Yes, I’ve settled on 29.8 grains of Reloder TS 15.5, CCI 450 primers, 105 gr Bergers (VLDs and Hybrids) in Lapua cases. Velocity varies with rifle but is in the 2725 - 2775 FPS range. There is case capacity for ~32 grains without being compressed if more powder/velocity is desired. Excessive pressure signs were observed near 31 grains.

It produces group sizes that average a little over 1” @ 300 yards. No doubt that I’m the limiting factor! Burns a bit on the ”dirty” side… I’m thinking due to the anti-coppering agent that works well!

So using Varget loading info should be a pretty good place to start I imagine?

Reloader 15.5 in Straight 6BR w/ 105's?

Anybody got this working and could you share your load? It's too expensive for me to use much of it, but I need alternatives to Varget. Thanks much.

I picked up 8 lbs the other week. Shot 108s, 107s, 105s. With two guns. 30,to 31grains.
This week, I shot some 95g vlds.with the 15.5.
Things look real good now. Getting 10 shot groups. Better. Seemed like With the 15.5 using the heavies I'd get one or two flyers.
One inch 300yard groups dropping one or two.
Probably is me, though.
I like 15.5
