Rate of twist

Best rate of twist for .204 Ruger? Looking at bullets of 45 gr and up, 1:9 or 1:12 twist?

I was wanting to shoot 60 gr. v-max's out of my 22-250, but the reloading manual says that when 60 gr bullets are shot out of a 1-14" rate-of-twist or slower that they will not stabilze. What all does this mean? Will they start to tumble or something like that, or will they have inconsistent groups?songdog

I may be wrong but here's what I figure. Ya know if ya throw a football real hard and don't put the spiral on it? Well it starts to tumble. If'n ya put the spin on it good enough she goes straight. I figure it's the same with twisting a bullet, if ya don't put enough "spiral" on it; tumble city.How'd I do everybody?

Songdog, Generally the heavier the bullet the tighter the twist to impart sufficient spin to the bullet. So your 1 in14 is great for 45 and 50 grain bullets...starts losing a little bit on 55 grain bullets and has lost a significant amount for a 60 grain bullet. Probably a 1 in 12 twist or 1 in 11 would work just fine for the load you want. Of course I'd just think about developing a rocketship load for your 45 or 50 grain bullets than investing in a new barrel....Or you could just go out and buy a new .22-250 with a 1 in 11 twist and you'd be there!!! The differences can sometimes be very subtle with twist differences but they are there. I have a heavy weight Krieger barrel with a 1 in 10 twist for my long range .308. It loves 168, 173, and 185 grain bullets. My standard weight Navy barrel with a 1 in 12 twist loves ball ammo and I can consistently outperform match ammo in my 1 in 12 twist rifle using ball ammo at 200 yards. Go figure...30 year old ball ammo outperforming Lake City Match ammo. The twist is truly significant to the accuracy of your load. Hope this helps a little. Beach

Okay, now that we are discussing rate-of-twist, I have a question. Obviously someone that handloads needs to refine loads for their individual setup. However, where is the best place to find rate-of-twist vs. bullet weight data? I bought a reloading press but will not use it until I am well-versed in the subject and have received ample instruction from a friend that knows more about it than I do.

will 270, great job explaining it, thats how I explain it to novices, too!Rate of twist can be found in any good reloading manual for each caliber in the individual load recommendation, where they tell you what primer is used, length of bbl. and all the specifics like that. Hornady probably has one of the best manuals for that type of info. Just buy all the manuals, you can never have enough anyway.

The greated the twist the more accurate...only at a point coreolis side drift must be corrected ,ever seen a doble barreled gun with one b rifled for a left twist and the other for the right ? this is a theme with a lot of string to it....
