[QUOTE="BountyHunter, post: 366343, member: 12"] Michael 1. First I ever heard of having to reduce powder due to min SAAMI chamber and I have or had 15-20+ of them, reamers to go with most. Most will go over what is listed as max powder to and safely. That is what most "match" chambers are unless they are also tight neck, which has nothing to do with the body dimensions and length of throat. Plus I have never seen anything ever written about that. Where did you find that at? 2. If any chamber has a short throat, it may not load some factory brass and that means you are jamming way into the lands and have hard closing. that is a given problem with any chamber. However, if you have a chamber like that it is poorly designed period and has nothing to do with min SAAMI. Reamer mftrs will make any reamer you want, but they all are very capable of putting out "standard" minimum SAAMI chambers that will fit any normal factory round and not cause high pressures. When you call and talk to them, that is the type they will normally recommend unless you are an experienced wildcatter and want something out of the ordinary. They will do that too. They will also discuss the type and weight of bullet you want to match the freebore. A reamer built specifically for a 30 cal 125 Btip touching the lands will not even chamber a 210 VLD. Sounds like someone gave you slightly short throated chambers if you are running into that issue and that is another problem on its own. BH [/QUOTE]
