I have 2 of them.
I have been trying to get a good target load for them and have a couple of questions
First the data.
Barrel slugs (on both) at .324
cases are milsurp sized and trimed to 8MM specs.
boolit is Lee C323-175-1R that after a little work drops water cooled at .3245 to.325
Have been using IMR 4895 , 28 grain up to 30.2 grain.
Now the questions.
I get a lot of blowback with the 4895 and tried16 grains of Unique and got none.
With 4895 got dirty barrel and what appeared as unburnt powder.
With Unique clean barrel and no unburnt powder.
Have a lot of 4895 and would like to keep shooting it but want to solve the dirty barrel , unburnt powder thing, blowback thing if possible.
Have read everything I could find but none seem to address my problem so am open to any constructive advice anyone is willing to share!
