[QUOTE="TopPin, post: 2951334, member: 109070"] If your going to run sub 280 grain cup and core bullets a 1-10 should be fine, but if your going to shoot a mono bullet, all copper your going to need to run a minimum of 1-9.3 above 260 grains. Heavy for caliber copper bullets will require more twist to stabilize past 800 yards. Trust me, I've tested it, a lot. If you're going to build a rifle I'd recommend at minimum to run a 1-9.3 twist or faster. It will not be detrimental to cup and core bullets, and will give you a broad spectrum of mono bullets to shoot as well. I look at barrel twist like spinning a top on a table especially with all copper bullets, the faster you can spin it the longer it takes for it to start to wobble. After that begins everything starts to unravel. Most common factory options are 1-9.3 and above in 338, now if you wanted to customize a barrel for heavy for caliber 338 offerings in a monolithic bullet (all copper) I’d order a 1-8 or 1-8.5 to stabilize the heavy coppers. Cup and core offers a lot more breathing room in barrel twist, as to responding better to slower twist rates at heavy for weight. [/QUOTE]
