[QUOTE="308plinkerVT, post: 3066825, member: 117224"] Just poking in an addition as I haven't yet seen it "together" in my skim of previous - the 7-8 range shouldn't be "too fast" in the "heavy for caliber" weight range here. Some of the early design lighter weight bullets would most likely be where you get any coming apart from "over" rotation. In the 62 (ballpark) and heavier you're "only" getting a tad more than 223/556 in published data and those run 7-8 too. Edit/add: 22CM is being reported by Peterson cartridge as 1-7. Depending what action you have there are alternut offerings out there in you can always split the difference with a 7.5 (my suggestion) in whatever chamber you choose. Figure out which pill you wish to give flight to and how fast you want to send it, functionally. I can tell you the 70 RDF does just fine in 7.5, three in 1 hole at 100 with the first workup. Shilen's chamber happens to have plenty of freebore in 22-250, leaving plenty of space for "combustion chamber", too. As the other gent later in this post wrote, he had zero expansion at very far range, something to keep in mind once these heavy pills drop enough velocity. [/QUOTE]
