I disremember where the thread was, but someone was asking about using Bullseye in rifle cases. I said that I prefer Unique as less positional and safer and then I remembered an article in Home Shop Machinist. A fellow turned cases for his 8MM Mauser that had alsmost solid bodies and a neck turned to slip fit his cast bullets and then he could use Bullseye down to 3 grains with no problems and no chance of S E E. I tried this last night with a 30-40 Krag. I turned a case that was chamber fit on the outside and had a long flash hole and enough space for a light charge of powder. 311 hole 1/2 way down the case. Whee Doggies it works! 4.0 of Bullseye and a soupcan bullet and it cuts a ragged hole at 25 yards. I have to deprime with a special tool but I suppose I could carry the 311 hole to the base of the shell and use a 310 tool. I don't think this has much advantage over the old supplemental chambers, but if you have the time and the tools it's a neat project and would turn your highpower into a neat squirrel rifle. I'll bet I'll look like Jed Clampett our shooting squirrels with an infantry Krag!
