Anyone can get 3100 fps, or 3200 fps, or even 3400 fps with a 180 grain BST. However, the axion still holds--there is no velocity gain without pressure increase. Maximum chamber pressures are not set arbitrarily; rather, they are set based upon physical and metallurgical limitations to ensure safety.
If the purpose of handloading is to gain velocity, we should each be shooting a 7.82 Warbird, or a 300 RUM or some other large capacity cartridge. However, unless one is able to afford to replace barrels with boring regularity, or pay for surgical repair of hands and heads following catastrophic case rupture, it is wise to work within stated pressure limits. The slight gain in velocity seldom translate into useable ballistics. It is an exceptional shooter than is capable of taking advantage of a velocity gain of less than three percent (with a concomitant pressure gain of fifteen percent). Lest someone should question my post, I have concerns for the average shooter's ability to recognise signs of excessive pressure until they are in trouble. I do not doubt the abilities of most of the fellows posting on this site, but I do wonder about the ability of many who self-identify as new hand loaders.
Doc, the question wasn't about a Lazzeroni or one of the huge Rem's. The question was about hitting 3100 fps with a 180 gr bullet out of a 24' barrel oh and of course at safe pressure since i forgot to include that thing we all follow in the original post.
There is a lot of published data out there with velocity very close to 3100fps. Did my question really warrant an extreme example you replied with?
Moreover, one of the fun parts of reloading is making everything work together and the ultimate result of it all at a safe level of course.
I am way too busy and have reloaded way too much to get into a saftey debate with you let alone anyone else. I certainly didn't come on the forum to have a run in with the reloading police.
Also, shame on you for assuming or treating me like I am part of a crowd that automatically assumes companies low ball the data so they dont get in trouble with the mindset,'well a ruger (or fill in the blank) will hold together if we go way over the listed data'
