i have some once fired LC 06 nato headstamp. some of the cases are allready under the 1.75 as short as 1.744. as long as i fit the projectile to the proper cartridge overall length am i good to go?

also while i am asking questions. i have 5 manuals none list the reciepe i found components for. for 223 gas gun

sierra .224 52 grain hpbt.
reloder 15

i have had siera 69 grain hpt with reloder 15 and use it in my .308 bolt gun.

Are you sure about this???

"i have had siera 69 grain hpt with reloder 15 and use it in my .308 bolt gun".....

I'm a Varget, H4895, BLC2, user, so no help on the RL 15....

100% sure i checked tons out of about a 3000 case batch i have. most are long. but some are short 1.744.

not even aliant powders site lists reloder 15 for 52 hpbt. but that is all i have

    I wouldn't worry about .005-.006". They'll get longer when you shoot them, anyway.

    The case length is not a problem. RL 15 does better with the heavier bullets. Alliant lists this for the 62's:

    .223 Remington Speer 62 gr FMJ IMI 2.255 - CCI 400 Reloder 15 25 2,832

    You could start with that but I think I would want to go with something that was a little more mainstream for the 223 52 grainer's. I like AA 2015, 2230. In the Hodgdon I like 335 or 322. They have all run very well in my AR's.
