[QUOTE="britz, post: 263834, member: 7865"] welcome to the wonderful confusing relm of reloading! What loading book do you have? Before taking any advice from the internet you should have read and reread at least one "how to" loading book by Hornady, speer, nosler...one of the manufacturers of components. If you can't recite most of the loading processes by memory, than I'd suggest going back and rereading the fist hundred or so pages again. Those books have lots of great information in them and they are the best advice you can get. If you don't have one than go to the upper right of the screen on your PC and click that little red x, go the the nearest sporting goods store and fork over the $30 bucks or so to get one and enjoy :) . . . . . . If you did read the manual several times than here is my opinion;) I beleive it would be hard to seat a bullet to deep. If the bullet's tapered spitzer is recessed into the case mouth your getting too deep imo, you might find some dificulty in chambering since the case mouth would be exposed. As a general rule of thumb... for hunting cartidges you should seat the bullet at least as deep into the case mouth as the bullet is wide. That means a 277 cal bullet should be seated at least .277 inches into the case mouth. AND if you seat the bullet so long that it is touching the rifling than you should be cautious when working up loads. You could see a slight pressure increase when you seat right up to the lands. I like to use the [url=http://data.hodgdon.com/cartridge_load.asp]Cartridge Loads - Hodgdon Reloading Data Center - data.hodgdon.com[/url] as a quick resource for loading. It gives you a good starting point and has a huge selection. Works great as long as you like using IMR and Hodgdon powders like I do. When ever you work up a load. YOu should always start at the low charge and slowly work your way up to the charge you like and you really shouldn't go above (I never give anyone advice to go above the recomended max).
