Hello friends!

I've had lots of fun with my 6.5x47 Lapua and bullets 130gr and less. I recently got a steal of a deal on a 6.5cm that came with 1000 143gr eldx bullets. I'm good to go with 6.5cm data (22.5" Tikka barrel, Peterson lrp, 210gm, 43gr imr4451 @2755fps) but was thinking I could try some of the 143s in my 6.5x47 as well.

My 6.5x47 lapua is on a 24" 5r benchmark with lapua brass and cci450s. I have varget, imr4451 and imr 7977 to play with (I have some older h4381 as well I think) and I was wondering if someone could run QL for me and help me out.

Appreciate it, cheers.

The IMR7977 appears to be too slow to work. It would certainly make a full case.
