Hoping some folks could give me some powders they have used with the big 22's here,I'll be using the Vais,With 75-80 grain A Max's and/or 80 SMK's.
And then I'm starting to doubt myself for going this direction for a 500 yard Varmint rifle.I know I'm probably ignoring the practical choice,something in the 6mm class, like a 6x47,or even a 6mm Vais.I have the Vais with a 14 twist bore,been shooting 50 grain bullets,and it's a bit worn out,thought I'd give the heavier bullets a try,so I already have the custom dies.I've got plenty of guns that shoot the light fast bullets,but nothing set up for the heavy's.
In my 22-243 ackleys 4 different rifles all eight and nine twist my best load hands down is 7828 ssc and the 80 a-amx. Speed ranges in 25 to 30 inch barrels 3450 to 3650fps. Your gun is way over kill for 500 yard shots. Have shot ground hogs to 700 yards [img]/ubbthreads/images/graemlins/ooo.gif[/img] with .223's and 75 a-max. At a 1000 and beyond you will have a real hammer. that little gun will keep up the big mags. shoot and enjoy your gun you won;t regret a fast twist 22 cal. I use the smaller 22 dasher at 1000 yards with good results.
I've gotta agree with everything that Reed said, especially his view on overkill @ 500yds. Out to 500yds, or so, I would prefer a 22-250 fast twist. It would provide great terminal performance and save you a lot of powder and throat wear. Out to 1,000 yds, the large case, fast twist, .224's rule for shooting varmints.
I've had my best luck with RE22 and the 75gr A-Max but that was before the 80gr A-Max became available. I think I'll give Reed's 7828 & 80 A-Max a try.
That's good encouragement.I'm commited with the .224 caliber,ordered a Lilja barrel yesterday.
500 yards is a long ways for me.It's been my experience with the light .22's,for leaving allot to be desired in the consistancy department at that range.Hoping I won't be disappointed with the performance of the heavier 80 grain,.22 bullets,really looking forward to it.
We have 7828,any other suggestions?
How about a 6xc necked down to 22? Or 22-250AI? Or 22 br fast twist? I had a 22-284 and it lasted about 700 rounds before it started blowing up Sierra MK's. TOO MUCH FOR 22! Sure was flat to 1000 yards though when it was working.
It liked RL25 and N170. About 53 grains if I remember correctly.
Any way you want to run them, a 6mm is superior in every way to a 22 cal unfortunately except recoil and that ain't much.
Oh, by the way, still have my 22-250 AI 8" twist and it shoots 80 grain Nosler J4's at 3350 from a 25" barrel and is actually a mild loaded gun. It prefers H4831sc and I have already had to run Tubb's TMS system down it to smooth out the firecracking at about 1200 rounds or so.
