10 MM w/ Magnum primers

[48 Months]

Hi, I reloaded 300 rds of 10 MM 155 gr Hornady XTC JHPs in various cases
before I realized the CCI Primers were Magnum (350). Powder is 8 grains
of Winchester Auto Comp Ball Powder. Hodgdon says I "should" be okay (doesn't give me a warm and fuzzy), but don't load anymore w/ Magnum 350's.

Any one have experience w/ 155 grain bullets and Magnum 350 primers?

8.0 grains Autocomp is the recommended Starting load with a 155 grain XTP according to Hodgdon manual.

Mag primers will not make one little bit of difference in a starting load.

Shoot them.

BTW: Loading mixed cases is going to make far more pressure difference between rounds then switching from standard to mag primers.
