6mm Dasher factory brass

[Stan Taylor]

Just what I needed. Makes sense cause the Petersons are heavier for sure. Thanks

My bad.
those four pieces of brass that I've been using to determine the primer pocket tightness I loaded 3 this evening and shot them at 300 yards to see how my groups was then I stepped down to the next Target and shot a 10 shot group unfired brass brand-new out-of-the-box with 31.5 of Varget and here is the results I'm shooting Barts 103 class bullets.
P.S. have to be careful on different lots of powder.

Well I'm still making brass for my 600 yd match I want it hit at least once the 4 pieces of brass I dedicated to see how the primer pockets are holding up I have 9 firings on those 4 case's no annealing or anything there still good and the numbers on the chronograph are still respectful.

@Stan Taylor. Any follow up thoughts on the Peterson Dasher brass? How is it performing for you? I know you have battle tested it by now. Thanks.

 

[Ccrider]

The .200 line went to .4705
I didn't measure how much the shoulder blew out.

Curios. Have you had any problems with bolt lift after multiple firings? What is your reamer diameter at the .200 line?

 

[Stan Taylor]

No I haven't I will look at reamer print in the morning.

Thanks

Thanks

The measurement at .200 in front of bolt face is .4709 and I have Harrell dies.

Bump - how’s the Peterson working out Stan? Still running those 4 cases lol.

I second that question on how it's going

Yep that sure is short, a Dasher sure doesn't have much neck anyway one caliber at 1.550 for a 1.560 chamber and even less for the 1.570 chamber.... sure nice to have the .020- .030 of neck.... jim

Jim, what is your opinion of using Norma Dasher brass and trimming to the length you want for Lapua Dasher chambers vs. the shorter Peterson Dasher brass?
