[QUOTE="L.Sherm, post: 1564355, member: 102083"] I'm no expert on the throat dia. by know means Guys like Alex, Rian and JE maybe better people to ask but hers my guess and please somebody correct me if I'm off track I think it has to do with building pressure, I think the smaller dia the caliber you may be able to get away with .0005 remember that's overall so its .0002.5 per side. I think on these bigger cartridges you gotta have a little more like the .0008 my 30 Nosler has.0010. I havent experimented with dia.or bore riders. I'm just now getting a pretty good grasp on freebore and starting to understand the lead angles a little better. I still have alot to learn. With a very small throat dia. And you get some bullets that are a little large could be not good, I know not all are the same. These are good questions though bspooley hopefully I can learn something from the responses also.
