Peterson Dasher Brass?

[wildcatter]

I get that fireforming stretches and thins the brass. That’s my point - the Peterson dasher brass doesn’t get stretched and thinned out in the neck and shoulder as much as 6BR.

That said, I have Peterson and Lapua 6BR brass and even there the Peterson is thicker. So it will have less capacity as 6BR or a variant, of course. But that difference is a fairer comparison from a benchrest shooters point of view. (Comparing 6 Dasher made from 6BR)

Peterson Dasher brass is probably quite popular with the PRS crowd, who want the performance level of Dasher without the fuss and tears when pieces don’t get picked up. Cracking over 3000fps isn’t as critical.

With 1052 good luck my buddies ain't get'n 3000 with Peterson, but any way you slice it, the Lapua will give more performance,,, I would never hassle with the dasher for less than 100 fps over the 6BR Norma to begin with, but when you go to Peterson in either version, 6BR or 6 Dasher. It won't have as much advantage as the Lapua. Now these guy's ain't afraid to blow primers trying to get what they had,, and both gave up, just telling it the way it is, hopefully to save others the disappointment!

I just bought a 6 Dasher Panda 17# built light 600 yard bench gun, I didn't even shoot it with less than 200 rounds on the new Krieger barrel, I sent it to my gun smith as soon as I got it, and it is now a 6x47 Lapua, no hassle, and obviously more performance, with brass as good as Lapua 6BR Norma, maybe better?.

Man, I don’t know how you tuned it or what you did or didn’t do; but to not absolutely fall in love with a 6 Dasher at 600 yards; I suspect you were not in tune. We have two dashers and they are absolute tack drivers. I do get that other rounds are far superior at 1000 yards. But I’ll take 6 dasher at 600 yards over any else. I have over 2100 rounds on my barrel and just last month shot a 400-31X and a 599-46X. Super easy to tune, drives tacks and I have 17 firings on my brass now. I’m shooting 105g Berger VLDs over 33.1g of RL-15. I’m getting average MV of 3072fps at 600ft of elevation with a 20 shot SD of 5-7fps.

A little off topic but: Is fireforming Dasher brass any different/more difficult than forming BRX brass?
I have a BRX and use the false shoulder method and have no problems.

PS: Just purchased some Peterson brass for my 6XC. Going to see how that compares to the WW 22-250 I have been using.

No Bob they both ff great just like your doing it

I agree with all that you said other than many are superior at 1000 yards… there’s been many many matches win at 1000 br with a Dasher There highly competitive at a 1000 yards

I didn't say they don't shoot, but I did say they are nomore accurate the parent round! The 6BR Norma has proven that well, but I won't spend the time making brass to get 100 fps or less over the parent round, and I place that fact,,, on what I have seen others do that competed with both cases! Once again proving, the same guys winning are going to win no matter which case the use!

My statement is that if I were going to go thru all the work to make a case for a Dasher I would not makle a case that gives up half the gain, just keep from making brass! And when you take the easy way out, using Peterson Brass, you are excepting only half the gain you get making your cases from Lapua brass, now you have no more than a hot 6BR round.

Lastly, I will say it again, I never owned a dasher! I have helped a couple buddies and watched how there performance suffered when switching to Peterson brass! So if you are getting 3050 fps in a dasher using Peterson brass,,,, your the minority, but with any loads using 105 or 109 grain bullets, your the only one I have herd of getting this magic performance, I know several doing that with Lapua brass,,, not Peterson!

I have no problem getting 2952 fps average from my standard no turn 6BR Norma rifle and will shoot .2" amo as far out as I have shot it, when I steer it right,,, in my Savage Axis,, I aint worried about 90 some more fps, proven winners again as well as record setters, have proven thats just a by product! Besides, my 95 grain loads shoot as well as any other load out 600 and I do get 3067 fps with that bullet and better accuracy! But I know plenty that do like the Dasher, some winn some get beat by 6x47's and others by 6BR Norma's, all fine shooting, but as lazy I am,, I just take the easiest route to the same results, inherently accurate cartridges!

I love my dashers and are so fun to shoot. I do know that at 1000 yards if the wind is calm, the dasher is awesome. If the wind really starts to whip, the dasher really struggles with getting blown around.

I shoot FF Lapua 6BR brass in my dasher with the load shown above. In my girlfriend’s dasher she is using 33.3-33.5g of RL-15 in Peterson brass with necks turned to .0115” with CCI450 primers. Shooting in Michigan at 650ft elevation we recorded the follow 10 shot strings over the past 2 months:

32F 3009fps SD 2.2
45F 3021fps SD 2.5
66F 3037fps SD 3.0
79F 3045fps SD 3.5
84F 3046fps SD 2.1

I’ll admit that I can get higher velocities out of my fireformed Lapua brass (I never load over 33.2g of RL-15 and I’m always over 3055fps), but the Pete brass has worked well for her thus far. Only time will tell if it proves to be as durable as the Lapua brass I’m using. I anneal every firing and have 16-18 firings on my brass now and it just keep hammering. It will be hard for me to select my brass for my new barrel but I’ll prob FF Lapua brass again because it makes it really easy to keep our brass separated.

I still love our dashers Wayne, but I have to admit that I have a barrel getting turned up now in .284 win to play with at 1000 yards.

I have two 6mm dasher rifles they both have no problem printing under 11/2” at 600 yrs with Peterson 6mm dasher brass, 32.5 gr varget, 105 bergers and we have just started test.

If you dont ever struggle to shoot under 2" at 600 regulatly, you sure have much better condition to shoot in than the dozens of 600 yard group and score shooters i know!

We've all puncked out 1 1/2" now and then @600, but to say I have no problem printing under 1 1/2" is something I usually only hear after a lot of bourban has been consumed!

Sorry don’t drink, my wife shot 1 5/8 with a perfect score at Palmetto Gun Club near Charleston, South Carolina earlier this year, l shoot 1 1/2 at the last shoot there with 4
National champions shooting, I took second. My wife and I have both shot the mile and she shot the 1 moa (17 1/2 plate) and immediately backed it up with the second shot. Like I said Peterson brass will shoot, and I can say my rifle always has shot 1 1/2 because it was the first time for me and the rifle shooting IBS 600 ever, probably just got lucky. (Both riles are in MPA chassis)
