I tried to shoot some .223s with a 50 gr. SX bullet in my M4 with a 1-8 barrel and they turned to smoke about 50 yards down range. They were only loaded to about 3000 fps so it was not the speed that melted them, it was the twist. I'm betting the other thin-jacketed bullets will do the same. Most of us that use a "walking around" varmint gun don't shoot 243 weight bullets (69-80 gr.) in our 22-250s. We shoot 45-55 gr. bullets. You can slow down the barrel twist for my part.
I had to smile at your post. It's why I attend this forum as often as I do. Just to see how other guys are getting it done. I've spent so much time hunting with guys that don't care about pelts....
Most of the local coyote hunters will laugh at you for not having a fast twist. Here the wind is always blowing & the shots can be as long as you care to shoot...
As far as bullet twist & bullet blow ups go, the V-max & ballistic tips I've shot have never come apart in mid air like the light jacketed spitzers often do. I can't say that I have experimented fully but those are my findings so far. I've had 40grn Blitzkings to some pretty incredible velocities & never shredded one (albeit we are talking translational velocity vs rotational velocity). Still even in a 12" twist, +4600fps should create some decent revs
Would it not be better to stay with the fast twist? You can alway drop the bullet weight & use the V-Max or blitzking etc for keeping pelts. Then you can switch over to the heavy weights for some long range pokes. If you stick with the slow twist, you're stuck with light weight bullets.
Just a thought with a little conversation thrown in.
