HNY to all - I'd appreciate some help on a couple basic things regarding loads for my 30-06. I'm trying to work up a hunting load for my M70 using IMR 4350 and Hornady Interlock 180 gr BTSP's. I'm seeing somewhat conflicting data, but may be misinterpreting it.
My Lee manual lists load data for "180 Grain Jacketed Bullet" as 49.1-53.0 grains. The Hodgdon website lists a 180 Gr SIE SPBT at 53.0-56.5 gn.
If I'm reading this right, Lee's max load is Hodgdon's minimum. From various posts I've see, it appears that several people have recommended about 55 gn of IMR 4350 for various 180 grain bullets.
Same issue for some 165 gn SP's: Lee lists 51.8-54.0 and Hodgdon shows 56.0-60.0
So a couple questions: 1) what is the right load range I should use?, and more generally 2) is load data generally interchangeable for bullets of the same weight (SP and BTSP, for example)?
Thanks!
