My 50s starting to look good

Recently I got some once fired 50 BMG Match brass from a mate so it spurred me into action this morning after a couriered upper didn't show....

There were 47 bits so along with 5 "normal" pieces of the same brand, I prepped them.... sized, trimmed, neck turned, primer pockets.
The match brass has much more consistent weights, thinner & softer necks as well as tighter primer pockets.
Still have a sore arm & side from sizing the brass.....

I loaded 3 lots of 3 with 750 Amaxs & 2218 starting from mag length going longer in 3mm steps.
The Steyr got a good clean, it's still coppering....

I had some rounds already loaded with the same load & mag length in my old FNB brass.
These were used to re-sight in the rifle after having the scope on my 40" 375 DCM.
They were predictable, with very average approx 2 moa groups at 217 yards.
Then I fired the first three with the same load, just better brass.....

The next two groups weren't as tight & lost a little velocity as they got closer to the lands, still a couple of mm away at my longest length.
Still very promising results, going to put a couple more grains of powder in tomorrow & have another go.
I was surprised that the Lee dies gave a total of only 0-1 thou out of concentricity

Hopefully the new brass has brought the HS M1 to life, tomorrow will tell.

I hope so it's a bloody heavy paper weight.....

If you want the best copper removal ever get some gun slick foaming bore cleaner.
It leaves eliminator and kg 12 for dead!
Good to see ya putting that brass to good use!
