new 22-6mm

[glt721]

I have been watching this forum for awhile and noticed there is some discussion about the 22-6mm. My new rifle should be done by the end of the month and I am very excited to get started. I have a 22-6mm based on a 721 Rem action with a 26 inch 1-14 twist Pac-Nor barrel. I am hoping to shoot 55-60 grain bullet. I have read a few posts that recommend H4831 and H380 powder. Is there any other recommendations on starting loads?

GLT -

Howdy !

First off, I DK what live game you may be after ?

But, let me run some thougths past you....

I made a .22-35 Rem wildcat some 30yr ago, shot it over 25 yrs

I too, started w/ a 1-14" twist; with intent to shoot 55gr bullets on live groundhog.

H380 is too fast a powder for the 22-6mm. It was also too fast in my 22-35, so I say what I say w/ confidence.

Best load was 41.2gr WW760 Hornady 55 SX FED LR Magnum Match

Alternate load was * 41.6gr VV160 55 "V"_MAX Fed LR Mag Match

* The above load got me into the 500yd club. When I finally connected @ 500, I was stupified at how relatively easy it was; and having succeeded w/ the same 24" 1-14 rifle I had been shooting for 23yr.

That got me thinking about a 1,000yd attempt on groundhog.
I re-barrelled to a 28" 1-8 SS K & P 5-groove .224" cal.
Again, I chambered in .22-35Rem, but throated for 75 "A"-Max.

My math showed that I would be able to put 450ft lb on a groundhog, out to 966yds. That would be good for a clean-kill @ 1,000yd. I never did get to try that 1,000yd groundhog shot.
However, my load for the above numbers was:
40.5gr AA3100 75 "A"-Max Fed LR Match @ 3,420fps,Accuracy)
" " " " Fed LR Magnum Match @ 3,500fps

And, I could still shoot groundhogs @ distances like 200yd
and not shoot-through.

My point:
Why not barrel w/ a 1-8 or faster twist, and preserve the capability to launch 75+ gr bullets ?

The 22-6mm is highly capable. Why not exploit that capability
by utilizing a fast-twist .224" cal barrel to provide and
all-aspect rifle ? 0 - 1,000yd capability.

Additionally, the expansion ratio of your proposed barrel
and chamber combo coupled w/ the ligher .224" cal bullets the
1-14 twist would require; portend a barrel burning set up.
Barrels ain't cheap.

At any rate, the .22-35 wiidcat data should give you some notion
that the powders you require will be even slower than WW760, H414; and I4350. More like AA3100, RL-19, I 4831; et al.

Best of luck in your endeavors.

Seems you'll be pushing it with a 14 twist, and don't hold your breath about shooting 60 grain bullets out of it.
Most of the discussion was aimed at using fast twist barrels and 75 grain bullets.....
and you can still shoot the lightweights with it.....

I have just finished one.
I also did the 1 in 8 twist for 80 gr bergers.
I have not got into loads to much yet but I have had good luck with RE22.

Thanks guys, I would have gotten back sooner but I had computer problems. I know I am out on the edge with a 22-6mm but what the hell, people stay up nights making new barrels.I will give your loads a try. Also, I am putting this rifle together with a lighter weight barrel for carrying around. Hopefully a few coyotes around here will get the full benefits of the 22-6mm.
