I am spending the day buillding up some more cases for the Remington rimless rifles I have. I took rimmed 30-30 cases and made them into 25-30 and 32 Remington. There are no more 32 and 25 made and the 30's are rare as hens teeth so I use W/W 30-30 brass. I have a couple cutters for the lathe and I first cut the rims off just under the base diameter of the case. Then i use another cutter to cut in the rebated rim. This is all done with jigs so the new rims are within 2 thousands of each other, somewhat better than factory. Then it's off to the dies and each case is sized in the appropriate die and a cast bullet is seated so when the round is chambered the ogive of the bullet pushed against the rfiling. This seats the case back into the breech tight for fire forming. Then I fire form each case with 7.5 grains of Red Dot. After fire forming the cases are cleaned and polished and are ready to go.
For hunting I load IMR 3031 or RX7 and run a 170 grain bullet to 2000 2100 in the 30 and 32. I am currently stockpiling 25's as I am seriously looking for a 25 Model 8 for my modest collection.
