Went by my LGA to get a pack of small rifle primers but they were out. Got some small rifle magnum primers instead. I was going to use them to reload some 30.06 on my new press. Can I use the magnums in place of the standard ones and if so should I make any adjustments to the powder charge.
First of all, the 30-06 uses large rifle primers. Small rifle primers are not going to work.
Second, unless your recipe calls for magnum primers, you should not be using them. Cartridges designated as "magnum" like the 7mm mag, 300 mag, etc... generally call for them where a standard cartridge like the 30-06 or 270 will not.
You need a good manual and do your homework before proceeding
. I would suggest the Speer, Hodgon, or Lyman manuals. Follow the advice in these books religiously and precisely----anything less can not only possibly damage/ruin an expensive firearm, but it can get you hurt.
Reloading is a great hobby and very safe, when carried out as prescribed by expert advice. Speaking from my own expereince, all of us started out as beginners who did not know much about it. I learned over time, from reading manuals and my own experience. So my advice is read all you can, and proceed slowly, building on your own experience.
