I noticed while developing a load for my 303Brit using a 180 grain jacketed bullet and H380 powder.....the Min OAL in the book states: 3.075" while the piece of paper that came with my dies states 2.915".....which is right? I've already loaded 5 bullets to the 2.915" specs and its seems to crush the powder :eek: so I figured I'd better double check in the book when I found this error. Sooooo now I'm debating if I can even safely shoot these off. Any imput would be greatly appreciated. I usually develop my loads using the min OAL and move up in size, I'm just looking for the correct starting measurement.

Steve's www.303british.com (the best .303 page on the net.) page says 3.075" for 180 grain bullets(so does my old Lyman manual). 3.0" for a 150 grain bullet and 2.920" for a 125 grain bullet.
Follow your manual and do so religiously.
 
Just give them 1 or 2 whacks with the bullet puller, enough to knock them part way out. Then just re-seat them to the desired length.
 
Joe's advice is good; but why not shoot them as-is?
If your loads are so hot that seating the bullet 0.15 deeper is going to cause problems, that load is too hot for an Enfield.

My Hornady manual lists 3.075 as the general max length. The longest individual load listed is with the 174gr FMJ and it's 2.980

I expect that 3.075 is the SAAMI maximin specification, and is the longest cartridge that will fit in most magazines.
As long as you aren't jamming the bullet hard into the lands with an already warm load, you'll be fine either way.
 
there is no point of loading cartridges to the minumum length....:redface:

load them so they will fit and function in the magazine/chamber, usually as long as possible, so accuracy will improve with a shorter jump to the lands
