6mm/22-250

[keithcandler]

In the 26" 6/250 that I had.....

I shot the
60's at 3800
65's at 3700
70'a 3550-3600 using 35.5g of WC844 which is Mil Surplus H335

After hunting with a guy in the early 80's with a 22 Cheatah with a small rifle primer, I will avoid any cartridge with a small rifle primer with any case capacity larger than the 204 for a rifle that could be used in 20* temps.

The guy had problems with hang fires all the time in cold temps. He changed primers, all of fresh lots, same problems with hang fires. This guy's load was 42g of IMR 4064 using a 52g Bullet.

This is one lesson that you only have to learn once.

I have turned 10,000+ of the PMC 7.62x39 brass to make ppc's out of to p. dog hunt with. Groups in the 2's and lower with the large primer are not uncommon at all in my Panda. The problem with the 7.62x39 brass is only PMC brass is tough enough to take the pressure of this cartridge. Win, Rem, Federal, and IMI will last two firings at the top pressure node that this cartridge loves to operate at, and for Varmints, you need the most speed that you can get.

For a guy that is a varmint hunter, the option of cheap brass is a HUGE option. Don't think for one minute that you will not be shooting groups in the 2's with the standard 6/250...for a guy that is a hunter...what more does he need?

It's hard to argue with a "Red Mist" shooter!

OK, two things.......

The CHeetah small primer brass IS NOT the same at all. I have tons of URBR brass and it's completely useless. YOU WILL NEVER experience this problem with the 6X47L.

And secondly the Lapua brass is easily and demonstrably MUCH CHEAPER than the other stuff.

Ohhh, and lastly, OK 3 things ...... EXPECT groups in the .2's with the 6X47

For real. (And THANK YOU KEITH for being honest about the true accuracy potential of the 6-250. Obviously the voice of experience.)

Al, that is some great news on the 6x47 brass...

no dbout that one of these are on my wish list!

I forgot to add one thing about the 6/250, it is kinda picky on loads. You don't see the extreme accuracy over a wide range of powder charges like you do on a 6 BR.

Another great option is the 6 Dasher. In '93 I had a 243 AI reamer ran in .100 further than the 6 BR, gotta tell you that this chambering is something very special. I shot more zero's with that cartridge than any 6 PPC that I have ever owned. This chamber was not finicky on powder charges for extreme accuracy. I would have still have been shooting this cartridge today if Lapua brass had been available back then.

The 6 Dasher fed through a 700 Magazine just fine with no alterations.

Keith,

This contention that the DAsher is mysteriously superior in some way to the 6X47 just baffles me! I don't have anything against it (Except calling the 6mm version a "DAsher" ) but just LOOK at this pic at the bottom of the page. Here are a virginal 6BR case and an equally pristine 6.5X47L case held in a caliper.

The inference is obvious, in fact my first experimental 6X47 is actually cut with my "perfect" 5th gen 6BR reamer.

The 6X47L simply IS an extended 6BR, done right, with a usable neck.........and incidentally the 6BR will do anything that a .243 can do, BETTER.

LOL

I have held a grudge against the short neck .243 Winchester POS for many years. I think anybody going to the .243 or it's many iteration and expecting to find accuracy, should join AA.

I would not mind having a chambering that would burn out a barrel from the same box of 100 cases (2,000 shots) has a lot of appeal to me. Buying great brass from Lapua is the first thing I look for in most rifles anyway.
