QL Request

[tddeangelo]

My father is working up loads for a new-to-him 6.5x55 M70 Fwt (yes, he got real lucky).

He's looking at a few different bullets.....notably the 125gr BT, 130gr AB, and 140gr PT.

If someone could run QL on those three, I'd really appreciate it!

Thanks!

Thanks, Mike!

 

[DrMike]

Du rien.

 

[SJB358]

Those look pretty danged good for that little Swede Tom! I imagine your Dad is going to fall in love with it once he gets it sorted out from the horrible trigger it must have! :lol:

 

[tddeangelo]

lol, yeah, it's a real heavy trigger. I think it weighed at 3lbs 14oz. with about nill for over travel or creep. He's suffering badly with that trigger.

Tom,

I've played a little with mine 7828 and 4350 with the 125's haven't done a lot but I think you will be better off with the 130's and 140's. In mine I can only load the 125's out to 3.100" because those are so short. At 3.150" they are barely in the neck. If you want some 125's I can send you some just PM me.
