time for a martini update, didnt get a chance over summer to have a play and Ill admit that real world testing with 2207 and the 256 Win case left me more than a little underwhelmed. Even thou Ive only got a handy 19 inch barrel speeds with the 70gr Blitzkings topped out at 2200fps
After grabbing some W296 for the my 357 magnum I decide it was probably worth trying in the 256. I also made the move to Rem 7.5 SR primers after having a few of the CCI's not going off previously.
Start load was 13.0gr, 3 shot groups, 0.3gr increments topping out at 14.8grs, just looking to see what sort of velocities W296 could develop and if there were any accurate loads. Magnetospeed sporter did the velocity duties
I loaded up 1 x 15.0gr just to see if I was getting close to max pressure for the case and to see if I still had easy extraction.
This was the final speed, more to come
When a guy is digging his own grave, you don’t fight him for the shovel.
Success leaves clues, Fools follow failure !
