[QUOTE="TOM H, post: 69071, member: 306"] Doug, hard to say which would be the best every barrel is different. I know alot of shooter who use 1/12 twist and consider them more of an all around twist for more bullet weights. If you look at Sako in their 30 cal they use 1/11 twist. You will be OK with a 1/12 and hard to say if the 1/10 would be better. In my 1/12 twist 30-338 there was only 8fps difference between the 165 and 180 gr bullets but almost 200fps slower going to the 200gr bullet. I've taken plenty of elk and deer with that 30-338 and 165 gr bullets barrel lenght is 26". My next 30-338 had a 1/10 twist barrel barrel length 24" and I've only shot 180gr bullets in that rifle and I just use it as a back up rifle to the other 30-338. I just had a pair of 300mag done up with 1/10 twist barrels for the 180 gr bullet one is a Lilja other a Kreiger. Kind of wanting to just try something different. Be interesting to see which barrel is faster. [/QUOTE]
