300 SMK Velocity

[mdmp5]

I got no chrony right now and I was wondering if someone could give me a ballpark of what I might be getting with the following setup:

Sako TRG42 338 LM with 26" barrel, 9.5 twist
300 SMK
H1000, starting with 92 gr

No signs of pressure as of now. Thanks in advance

bump for views

I get 2700 with 88 grains of H1000 in s&b brass. Rifle is a Barrett 98b with 26 inch barrel.

You get pressure if you step it up? 88 seems light

I worked up to 91 but accuracy was best at 88.

wow great shooting

Thanks, I was surprised at the accuracy of such a big cartridge. A good muzzle brake helps also.

Here is a velocity workup I did with H1000 for the 300g SMKs. I'm running a 30" barrel, LabRadar chrono, at 60 deg. F. Primers were looking a little flat a slightly cratered around 91.5.
