7 SAUM H4350 velocities/load data (short action)

[BuckeyeRifleman]

Working up loads for this upcoming fall in my new 7 SAUM. This is in a short action with a 22in barrel. Working up loss for both 168 gr and 175 gr bullets. Using H4350 because I have an 8lb jug and everything else is unobtainable at the moment.

So far I've worked up to 57.5 grains under the 168 gr bullets with no pressure signs. This is 1.5 gr above max and getting me 2821 FPS chronoed with my Labradar with a SD of 7.1.

Just curious what other people have worked up to in the 7 SAUM and H4350. Accuracy has been excellent in nearly every load so far (worked up from 54.5 going up my .5)

I never tried 4350 in my 7 SAUM.

My MagnetoSpeed was down during my early testing but I did get speeds after getting a new Bayonet for RL25, RL26 and H1000. I have 107 rds thru mine so it is probably past breakin and ready to re-visit some of the other powders.

The forever sold out RL26 is my favorite in the 7SAUM

168 gr and 175

The construction of the bullet has a lot to do with pressure.
Long bearing surfaces & thick jackets increase pressure.
Like this. Nosler accubond.
