Anyone considering the shotgun action conversion TO RIFLE WITHOUT DECIDING TO BUSH THE STRIKER HOLES TO A SMALLER, MORE SUPPORTIVE DIAMETER let me point out 2 things.
A 45 COLT 280 gr SAA over 8.0 gr Unique will come out at 1,100 fps and cause wonderful damage to test media. Calculated pressure at 16K and life is good.
HOWEVER, FOR THE 30-30, 173gr cast FN using 10gr unique has a calculated velocity at 1470 and pressure at 30K.
The chrony read 1472, and the stock wrist splitting from the primer rupture says that 30K is too damn high for rifle primers over an unbushed firing pin hole.
The action is still OK, and the wrist split is minimal - but it could have been worse. Thank God for lead sleds, safety glasses and whatever else He gave me today.
Save any criticism, please. I just want folks to know before they jump.
If you want any other specifics, ask away....
