180 SST (Good Results)

[samson]

Went to the range today and fired a batch of SST's loaded with RL22. The incriments were at .5 grn. AOL was at 3.594. The 75 grains of RL22 and Norma Brass capped with a Fed 215 produced 3 shot groups at .23". I think I've found my load. I need to chronograph and sample some other seating depths. I will let you know what happens.( FYI this is a factory Model 70 in a 300 winchester magnum.)

 

[long action]

I am using 74.5 grains of RL22. OAL of 3.370 in my Sendero 300 Win mag. Six shots one hole at 3032 FPS.

I wish I could seat mine down that far. I have to use it in a single shot form due to not fitting in the mag.
