RE-15 max load? 175 SMK + Lapua brass

[One_Man]

I just loaded 25 rounds as follows:

1x fired Lapua brass neck sized .336"
43.0gr Reloader 15
Fed 210m
175 SMK
2.241" OAL 0.010" jump (2.820" COAL)

Couldnt find a published max load for this combo, but I previously loaded the same charge of Varget with no issues. Is this a pretty safe load? I am assuming that Varget and RE-15 are essentially interchangeable.

43.1 gr RL-15 and Lapua brass with a 175 SMK is what I have used successfully in the past with my KMW (95 palma chamber). Your load mirrors almost exactly as my load.

Rl15 and target are not interchangeable. 44.3 is about max for rl15 and I'd say that 45.1 is it for varget. What you have is a good load. I use 43.2 of rl15 in neck sized fgmm brass. It will hold .4s and .5s at 100 1.4" at 200.

Is the case capacity of Lapua and FGMM about the same?

I was just thinking, what does the lapua .308 brass weigh on avg. Maybe you can help with that.

I use Rl-15 and Varget for the 175gr match bullets.
Win cases, Hornady match cases, and R-P cases.

Win cases avg 158grs
R-P cases avg 162grs
Hornady match cases avg 173grs

With that said the Win and R-P cases like 43.5grs Rl-15, but have loaded them to 45grs with not much sign of presure problems. I tested the Hornady cases and rant them up to 44.5grs of Rl-15 with no signs. 43.5 shot best thou.

Varget seems to be not as predictible. Win cases like 44.0grs, R-P like 43.5 and the Hornady like 43.0 grs.

All like loads per case will shoot .5" 5 shot groups or better.

Just weighed one for you. .308 Lapua brass 1x fired, cleaned in ultrasonic cleaner weighed 173.5 grains
