Got some ammo in from NSA for tha 30 cal challenger sl.
I got the 61 grain .303
I have also been testing out my hammer spring adjuster with custom spring.
First 9 shots from 3000 to 2500 was with no chrony and at 50 yards. 1st shot was to the right. No adjustments and kept firing. Group moved to the left exactly where I was aiming.perfect and awesome.
Next I recharged to 3200 and reloaded another mag for some chrony work.
809fps up to 848 and back to 822 for the 9th. Put the gun on the charger again to see the actual pressure and it was at 2700/2750.
Tomorrow I will start adding some preload with the adjuster and start at 3500/3600 to see if we can push the 100fpe mark.
I would really like to see these NSA's fly faster than 850fps.
Boy do they ping the gong at 50 yards.

And yes, I did design a working drop in hammer spring adjuster for our challengers.😛
