building a 22 cal varmint gun

[B23]

.22 CM Run the Lapua 6CM brass through the die and your done.

Not because I'm any particular Creedmoor fan but this would definitely be the most practical choice. If my gunsmith didn't offer formed brass for the 22-243 Improved he's building me, this is exactly what I'd be going with.

I think the OP is confused. Varmint rifle as he states to me is for woodchucks, Prairie dogs, ground squirrels and the like. So 22-250 with lighter bullets. But what he really wants is a Predator rifle, Coyotes, Bob cats etc. and in that respect he needs a .243 with the heavier bullets it can easily handle. Now I have killed many Coyotes at varying ranges with the 22-250 and 55 grain bullets, it can do the job, however 80 grain bullets on Squirrels is a bit over kill, and maybe not as visually as spectacular as one might think. Tiny bullets traveling and spinning fast get the red mist going on the smaller critters.

Just my 34.19 Lira worth

That would imply the bullets bending their trajectory back into the line of aim after deviating out of the line of aim. This has come up before on other sites. No one has offered any compelling evidence for it to be true.
There are many factors involved, something is being overlooked as to why it seems to be happening.

I have a picture in my mind from trying to understand exterior ballistics, they talk about yaw, nutation and precession and more. Bullets that are not flying “straight” or “have not stabilized” results in greater dispersion on the target. If some bullets more stabilized and flew more straighter as distance increased, seems like dispersion would decrease.
My sample is too small but I saw it 3 groups at 100 and 200. A guy can dream.
Somebody who knows this stuff science-like should contribute.

Yes, dispersion would decrease, but the bullets would not correct for the previous dispersion. Dispersion would decrease from the already changed flight path. The chances of a bullet changing direction of dispersion seems to me to be exceedingly small.

Be that as it may, I still like your rifle.

I have a 22-47, started life as a 22-250, wanted a little more speed with bigger bullets and didn’t want to fireform so when the barrel was shot out went that direction. Shoots 75 grain ELDM at 3500 and the brass lasts forever. Very accurate as well. One of my favorite rifles.

I 'LL SAY THIS FOR WHAT THE LITTLE 22BR IS ITS HARD TO BEAT OR IT IS IN MY CAMP ANYWAY AND THE BRASS WILL LAST TEN LONGER THAN MOST
