Thought I would share some Magnetospeed readings from the range tonight.

I was really pretty suprised how small the SD was on the HSM ammo.

Sucks that the round with the worst BC had the best internal ballistics. All depends on usage of course!

Yea that was my thinking as well haha.

I’d like to see unsuppressed data to see if there is any boost with the can. I’m getting about 35fps out of my 26” barreled SAKO TRG 22 .308 using Black Hills 180 grain Accubonds.

How many rounds of each load was fired/measured?
