A 110 grain Vmax from the 300RUM is twice a 220 Swift, twice the bullet, twice the powder, twice the grin.
You are 100% correct. Math does not lie! If you understand the math, one can decipher for themselves the truth!You gotta work on some punctuation, it's difficult to follow.
It isn't speculation, it's fact that length is what needs stabilizing; not weight.
Whether or not that marginal stability will be acceptable in your particular application, is always subject to personal testing.
I remember reading either an article or a book that mentioned Fred Barnes and his feelings on twist rate, bullet length and stabilization. I was a teenager at the time, but it always stuck with me. If I remember correctly, He theorized that bullet weight versus bore size was key to penetration (and of course bullet construction). He said that you could create a .22 caliber rifle that could reliably take Deer and even Elk if you had enough weight. I "think" he proposed a 22 "super twist" that could stabilize a 90-100 gr bullet. I really liked reading about him as he seemed ahead of his time back in the 30's-50's.Remember it's length, not weight that needs stabilized. The 55gr Vmax is at best, marginally stable in a 12-twist Swift even at max poke.
I keep a 22 Mag in my garage on the off chance I get a hog within 75 yds. or so. They don't like getting shot at and after a couple, I haven't seen any in some time. I always wondered about using my 17 HMR, eye shot. Ammo for both is kind of dear, so I haven't been target shooting except some 22 Mag. I check Academy periodically for either and will buy up all I can next time I run into any. I have less than 150 17 HMR left, but about 70 of the 20 grainers. I'll remember your suggestion on that.For folks that haven't heard me talk about shooting coyotes with a 17hmr before there was a learning curve for me when I got the rifle, absolutely do not use the plastic tipped 17gr varmint rounds, they blow up on the ribs and shoulders. The 20gr. CCI small game bullet works very well however not many drop in their tracks. I'm down to just a few rounds of them and will be forced to start using some fmj CCI rounds, I'll intentionally aim for the front shoulder to try and make them tumble or create secondary projectiles ala bone. Or I could just put the 22mag barrel on, I have some gamekings for it.
