Has any of you folks tried 203B with lighter bullets. like 123 gr.?

It is real close to rl15 as far as burn rate a lot of long range shooters use rl 15 in there 6.5x47 in completion at long range an shoot very well I see no reason you cant use 203b as a alternative.

Thanks, that's what i thought. I just finished making a new round in 6.5 from 308 brass. Should hold about 42 grains of powder. I just ran my 6.5BR reamer in until I got a body length of 1.325 at the shoulder start. It should fire form out with little taper and a 30 degree shoulder. looking forward to shooting it.

What parent case are you going try an shoot Stan

Sorry didn't read about 308 case.

The 308 case has the same pressure as the 6.5X47L [ 62,000 psi] so it should be a very close round. That's the unfired case in the middle next to a 30BR.

Nice what is overall length of case.

1.808 before fire forming.
