6mm Dasher brass

Whats the way to make obtain 6mm dasher brass

xdshooter,
Take 6br brass, I like heavy fb non-mollied bullets jammed .030 or so, 30 grains of Varget or RL-15 and a 450 primer, that is my preferred method. Also you can open the 6br brass up to 6.5 with a mandrel , then partial size the neck back down to 6mm for a crush fit, called a false shoulder, then there is the cow method, you will need a false shoulder a few grains of pistol powder, then fill with cream of wheat, capped off with some wax (very messy ) I prefer the fist method.

I believe on the home page under 6br improved cartridges there is a detailed explanation on fireforming brass for the dasher and other variants.

I've given up on this method and cringe that I still have 100 rounds so loaded to shoot in my gun.

I'm jammed .030" with 75gr v-maxes using a .265 neck bushing with Lapua blue box brass gives me .004" tension.

There are still several rounds per 100 that don't fire. Then one must tip the muzzle up to the sky (to try to keep powder from dispersing into the action) and extract the round, which will likely leave the bullet jammed in the lands. Then back to the rest with the gun and tap the bullet out from the muzzle.
Last weeks trip to the range this routine wasn't good enough and I ended up with my jewel trigger bound up with a powder granule after firing off only a few rounds.
Not to mention that I usually see .010" growth in case length when forming with this method.
Expanding to form a false shoulder might be more work on the front end but I'll do it for any future dasher brass I need to make up.

The first 100 cases I made I with the false shoulder method and lost 6 cases to split shoulders. The set of 100 I just made the necks were turned for .267 loaded round with BIB 108's, I sized them with a .264 bushing, jammed them .030, I put 32g H4350 in cases primed with CCI450's. I fired 34 of them, all went off fine and so accurate I saved the last 66 for an upcoming 3x600 F-Class match. They all went off and I came in 3rd overall. I ended up losing only 1 case. From now on I will stick with the "FIST" method.

Hmmm. I suspect the contrast in our success with the jam method might lie in bullet ogive and/or throat lead angle.
I wish my experience were like yours, but I'd gladly take a few split shoulders rather than "click-damn" that I've been working through.

Alf,
That is wayyyyy funny right there I stand 100% corrected and apologize I thought you were mocking me or something,..as per usual I just cant spell, since fist is a word sp ck didn't catch it ;D Thanks Alf for setting me straight
Wayne.

Now to all of you that are having trouble fireforming your dashers, I just came up from the range to eat lunch and I just got done fireforming 50 dashers, not one split case and not one miss fire with a .030 jam on non-coated flat base 100 grain hunting bullets, 30 grains of Varget and 450 primers, after I eat my sandwich and head back down to the range I am going to do 47 more pieces DON'T ASK ABOUT THE OTHER THREE :'( and we will see if my luck holds. On my 6brx with a Witchita action I don't think it would be possible to fireform 50 cases with it, same problems as mentioned and I tried all methods ??? Gave up and used my sons savage to fireform with only about two or three out of fifty don't go off in it but there is enough neck tension I have yet to have powder loose in my rifle. Some guns like it and some don't I guess.

I wonder if different lots of primers or brass and their hardness have anything to do with going or the split necks. Possibly different pin spring strengths cause people to have vastly different experiences.

I'm using 450's. Prolly should be using 205's when fireforming but I never remember to do so. Always just reach for the 450's when 6br/dasher/6x47 cases are in the blocks.

I disagree,... the 205 cups are to soft and I have had trouble with piercing them when fireforming, I would stick with the 450's there harder, I have heard the wolf primers are the way to go but unfortunately we don't have them out west.

Sorry Wayne, I saw it zipped right over your head the first time and it was too funny to let it slide.
