Not to hijack the thread, but have you done any shooting for accuracy with that Herters ammo in .30 Carbine ?
I recently bought a couple boxes of it and fired some of it through a Ruger Blackhawk chambered in .30 Carbine. The accuracy was horrible. I haven't tried it yet in my M1 Carbine. But, out of the revolver, the accuracy was so bad, that I quit shooting after 12 rounds: I was wasting my time.
With this recent ammo shortage, this Herters stuff was almost the only thing on the shelf. So, I thought, what the heck I would give it a try.
You know the rest. In the books you have read
How the British Regulars fired and fled,
How the farmers gave them ball for ball,
From behind each fence and farmyard wall,
Chasing the redcoats down the lane,
Then crossing the fields to emerge again
Under the trees at the turn of the road,
And only pausing to fire and load.
