[QUOTE="nkyshooter, post: 2151728, member: 83787"] Adding this for others who might benefit from it: 30 Sherman Magnum - FIREFORMING LOAD [LIST] [*]Case: ADG 300 PRC unfired case [*]Primer: Remington 9 1/2 LR Magnum [*]Bullet: Hornady 178g HPBT Match [*]Powder: H4831sc ... 78.0g (Hornady shows 69.1-82.5g) [*]COAL: 3.500" (my chamber is 3.567" at the lands) [/LIST] Case and primer showed no signs of pressure and the case was very well formed. Nice sharp shoulders and nothing funky encountered. Pre and Post fire neck runout was consistent at under +/-.001" as was case wall just before wall/shoulder junction. Post fireformed case capacity was 96.8g H2O. Unfired 300 PRC case length was 2.577" (SAAMI Max = 2.580"). Fire formed case length was 2.570" (SAAMI Trim = 2.565"). I have not yet tested this load for es/sd/avg MV or for groups but will add more to these notes as I'm fire forming & breaking in the barrel. [/QUOTE]
