[QUOTE="elkaholic, post: 761141, member: 13833"] The capacity will be about 72 grains. Fire forming will be VERY minimal. A very slight stretch to the body diameter and moving the shoulder from 35 to 40 degrees. The shoulder would be bumped back a little more than 1/4". The case would then be trimmed to approx. 1.83" and either loaded with a bullet and formed or using the shotgun powder/cream of wheat method. Retumbo, H1000, RL 25, would all be good options as well as even powders like RL 17. The 6.5 extreme is a different case. It is based on the 300 RCM which is a shortened 375 Ruger case (head dia. .530" vs the .550" on this case. This is why I am able to get the capacity/velocity out of this cartridge and still be a true short action round. I hope this helps......Rich [/QUOTE]
