A really promising loading

[wvfarrier]

I have been working on this load for quite a while and finally got it sorted out.

The 130 grain Speer Varmint.   I tried several powders and finally settled on Lil Gun with them seated at 2.05"

Velocity from my henry ultimate 300blk is 2225fps (about 1975 at 100 yards) and accuracy was excellent at 1.05" for a 5 shot group using a red dot (trijicon mro).

Initially I could not get 100% feeding reliability.  The last round would jam hard into the feedramp.  I toyed with this for a while and finally tried a metal duramag...poof..the problem vanished.  I ran about 75rds without a single feeding issue, tried a pmag and the problem returned so these are metal mag only but really accurate and should be excellent as an SD/hunting load.

Im using Shellshock NAS3 brass with these.

Very nice! I have had similar results with the 125 gr Speer TNT.

300 blackout seems to like that weight bullet.

Very nice!
I went with the Speer 125gr TNT over H110. It has given excellent results, but I haven't used it on game to date. From what I've read, however, it is supposed to work well.
