Glad I found this thread. I have a 300 WSM with a 22" Proof CF en route. I have H4350 and RL16 available. Will be picking up Hornady brass unless Lapua becomes available soon.

I'd like to run 190gr Accubond LRs, but I cannot find a starting point for any of these combos. Am I looking at the wrong powders?

I did, but it doesn't have any of the powders I own listed when I know H4350 can be used.

I worked up to pressure at 62.0 H4350, Norma brass, CCI 250’s, with 190 LRAB in a 24” Proof Carbon prefit. Backed off from there to my final load pushing them at 2880 fps. Seems to align closely with the 2209 data listed.

62.0 seems low for H4350 when Nosler calls for max loads of Hybrid 100v at 63.5 and Hunter at 65.0. H4350 burn rate is about smack in the middle of those 2. That speed though!

Look at Hodgdon data for a 190 class projectile; https://hodgdonreloading.com/rldc/

It was a gorgeous day today. Temps were 75 to 80 degrees. Mostly overcast. Cool breeze. So I took advantage of it.

300 Win Mag

Lapua brass
Berger 208 LRHT
Federal 215 primers (Blue box, not FGMM)
Winchester Sta Ball HD
CBTO: 2.620" (COAL 3.655ish)

Shot from 30" x 1:10 tube.

Gun seems to like this combo. Velocity started in low 2900's and the top end was mid 3000's. Wife has the chronograph info on her phone, so I can edit in the velocities later if anyone asks. No pressure signs at all.

1 inch target dots.
