the easiest way to get an 8 mauser to be a 30-06 is to buy an 8mm mold.
there isn't a bit of difference between the two.
so much so i went and bought some jacketed bullets for my 8 mauser that weigh 170grs. so i wasn't just shooting 150's at 2800 fps through two different rifles.
then of course i finally figured out i have some Berger J-4 jackets that make 168gr. bullets for the 0-6 up on the top shelf.
How dare you reply with logic and practical recommendations!!!
I have all the stuff to do 8mm mauser. Just for some reason isn't as fun.
You know what's a fine rifle for cast bullets?
Type 99 Arisaka.. 7.7. Comes with a pre-installed peep sight, very light weight and has bonus anti aircraft sights!
I did a test in April, lee 160, lyman 311672, and lyman 311291. All powder coated and sized in groups of .310, .311 and .312
Weirdly the lee 160 did the best. This summer I'm playing around with the 314299 and NOEs version of the wonderful 3118. The Type 99 is just a wonderful cast bullet rifle.
But if I were granted a wish. I'd wish for a R.F. Sedgley sporterized 1903 in 30-06. I had one in K-hornet that I bought for 500 bucks. Should have kept that one.
