Re: Wildcat question

In my 22-243 AI I would shoot the 75gr A-max @ 3,670 ft/sec. This load was extremely accurate in my heavy varmint rig. Best group was .625" @ 600 yards. (lasered & witnessed)

You could easily exceed 5,000 ft sec if you reduced bullet wight to 30gr. I never bothered with light-weight .224 bullets because the BC was so low.

Plenty of good 75gr - 90gr .224 bullets for the 22-6mm, 22-284, or 22-06 if you really want a longrange .224 based rifle. I'm guessing that there would be no practical advantage to a 22-7mm mag. If there were 120gr .224 bullets and barrels twisted accordingly then the extremely overbored 22-7mm might make a very interesting and entertaining cartridge. However, throat life would be rather limited.

Re: Wildcat question

HEy Varmit hunter whats the advatntage of the 22-243 AI a 243 wsm? Not sure the balistics of the wsm but have to be close? I have a 6.5-243 haven't messed with it yet. I know a AI improved .223 can get about 150 fps more. I would love to have a gun that could push a 70-75 grain bullet around the upper three grand range and be a laser.

But back then it was cheap to do macien work and he had access to a lot of matterials
I would recomend the .223 WSSM or the .243 WSSM. Because these are factory chamberings
and they are very fast.

I built a .223 WSSM a while back and did some testing and due to sholder surgery have not
completed all of my testing but hope to soon.

So far I have loaded the 62gr bullets to 3915 ft/sec with no pressure signs and a standard deviation of 0006 ft/sec.

My goal is to push the 40gr Blistic tip to over 4400ft/sec in a 1 in 15 twist 3 grove Lilja.

You can buy a rifle already chamberd in these rounds if you don't want a custom but you
probably cant reach these velocitys.

These days there are so many hot cartriges available a wild cat is not nessary unless you
just want one.

Re: Wildcat question

Yes, the 22 cheetah. I actually have one. It was made by my grandfather, and i'm sure it still shoots, but i won't use it. He used to shoot five shots in a 30 caliber hole with it. still have some of his targets.
