6 mm dasher

[maddysdad]

what is the main differance between old and new case as far as qualaty of brass goes.

I'll try to answer this. The Dasher started as a wildcat. Cases were made from Lapua 6BR-N brass which is as good as it gets. Norma started making brass but it was hard to find and not felt to be the equal of fireformed Lapua. Then along came Alpha and Peterson. I have experience with Norma, Peterson, and Alpha. All three work for Me in my rifle. I guess I like the Alpha the best and the Norma the least. The case capacity of all three vary slightly so if you are going to push them you must take that into consideration. My load is not max, so I use it in all three types with no issues. If you have Lapua 6BR-Norma brass and want to fireform your own with the extra cost in bullets, powder, primers, and time you will have brass just as good as the other three if you do it right. My personal recommendation would be Alpha and then Peterson, but you probably couldn't go wrong with any of the four. As cases age, I assume you mean times the have been loaded, they can have a bunch of changes. There are some ways to correct these changes or prevent some of the changes, but all cases will eventually fail if reloaded enough times. YMMV

im just getting into the dasher myself. i have some of the 6br lapua thats fireformed and im running 32gr of varget in them at 2890. 1/4 inch moa. i have since got some peterson to try out to avoid the waste of components. i am at 30.4 gr in the peterson case with .3 moa but slower speed at 2805. what velocity are you getting with running same load in all the brass?

Brawley, the only group shooting I am doing with my Dasher is at 600 yards and if I handle the wind I can get sub 1/2 MOA. I generally use the Dasher for F-Class Mid Range at 600 yards. I made High Master with it and have several clean targets one with 16 X's. The only crono I have in my records is with a Berger 105 Hybrid, VV N-135, Norma brass, and a Remington 7 1/2 primer at 2,927 fps. I generally use Varget or SW Precision and that Berger bullet. I am probably going 2,900+ and now use CCI 450's. Since all my shooting is known distance I am only interested in accuracy and fast enough velocity. I use both Peterson and Alpha brass now and really either one works for me.

The Norma Dasher Brass has the .050 longer neck.
I have Two of them, with 105 Berger HB they shoot lights out at 600 yards. F/Class Target. It will do a fine job at 1000 yards.

Lapua fire formed brass will last much longer before the primer pockets get loose. I shoot Br with one and I have 15-20 firings on some cases with no issues. I shoot 33.5-8gr of Varget @ 3060 with a 103 class bullet. H4895 @ 32.2-3.

Truth. If your reamer and dies are a good match and you anneal regularly, Lapua will hang in there for an incredibly long time. I have brass with more than 30 cycles and they're still going strong. They may outlast me.

Like JLT said… my fire formed Lapua brass have more than 30 shots on them and I still do not have plans to replace them yet…

It is of remarkable, amazing quality. I should add that I have a couple of hundred Alpha Munitions cases dedicated to another rifle and that is very, very consistent stuff. It measured and weighed more consistently than the fireformed and trimmed Lapua, enough to make a Six Sigma Master Black Belt do a double take. Durability is still an open question. The Alpha brass has seven or eight firings on it (not sure, have to check my notes) and it is in fine shape. Will it make 30? Don't know and don't yet have a guess.

Results on the target are not altogether different. If one yields better precision than the other, I can't shoot the difference.
