So I finished my last PSA testing and here you go:
This time it's the 77TMK loads: my reload vs PSA vs BHA offering.
The Test: 200yd, benched, 10 shots slow fire with a 20" Krieger SR barrel and M4 Scope on top.
TLDR: The PSA quality was REALLY BAD with these but it shot ok. As in a buggered bullet and a case some "ring" in it etc......and BAD run out. Not "5.56" pressure either if you care.
The one shot in the BHA group ruined it but I didn't call it..............so no excuses.
My hand load rocks.
PSA 77TMK ammo:
I pulled several and found:
-primer not crimped or sealed.
-about 25.4 grains of unknown powder
-Bullet not sealed but crimped despite not having a cannelure.
-RUN OUT WAS BAD....... rolling the cartridges on a flat surface.......you could watch the tip/bullet wobble around off center
-One round had a mangled bullet in it. Another had a ring around the case.
Details:
-shot at an elevation of 5545ft.
-Conditions: cool (67F), breezy and bright.
-Rifle: Krieger 20" SR barrel with 646rds on it, Match chamber. Leupold mk4 scope on it.
-shot off bench......... shoot one, dry fire one. Bore snaked between different loads.
-Chrono was 15ft from muzzle.
