Good point Dogjaw, The Lyman 46 shows data for 748 and H335 with standard large rifle primers and I have the SPEER #11 also and as you know all the Winchester and Hodgdon Ball powder loads were developed with magnum primers so I was going to ask if they are really necessary? Another powder I am interested in other than Varget is Ramshot Tac, which is just after 335 on their burn rate chart and is a ball powder also, supposedly without temperature sensitivity issues. Thanks for all the help!
I've always used CCI magnum primers with 748 powder in the 30-30 per the Speer manual. I've had groups as tight as 1" with a 4 power scope at 100 yards using this load. I'm not about to mess with what works.
There are three kinds of men:
1) The ones that learn by reading.
2) The few who learn by observation.
3) The rest of them have to pee on the electric fence and find out for themselves..........
