First off, I would just like to hi, and to thank everyone for taking the time to create such a great site with more knowledge than I could ever imagine.
I've just begun reloading in the past year, and since the few reloading manuals I have differ, I'd like to get some concrete insight into the issue of minimum OAL. I'm starting to reload for my .270 Winchester, and this is the first cartridge that I'm going to use a bullet with a cannelure. Now, I've heard from some of my reloading buddies that loading to the cannelure is just fine. But isn't a cannelure just for keeping the jacket secured to the core? I know it helps if you plan on crimping the round, but not as a be-all/end-all seating depth point. My Lee manual says that COL is 3.180" and one I test seated was to 3.175" at the middle of the cannelure, so I was just wondering if the .005" will make the pressures THAT high that it would be unsafe.
Also, this load is for my Stevens 200 cheapo hunting rig, that shoots remarkably well with the 130gr Core-lokt factory ammo, and all I'm trying to do is make a clone load for it. So far I'm at 43.5g of IMR-4064, CCI 200 LR primers, Rem. brass and I'm using Hornady 130g SP Interlocks for the pill. Haven't shot any of them so far, so I don't have any pressure signs to go from, but I don't want to load a box then have to pull the pills cause I screwed up.
Sorry for the short novel on my first post, but I wanted to try to be as clear as possible. Thanks alot.
