On a whim I got a MP moulds brass hbwc mould - a thing of beauty!
Here in the UK Marlins are used for paper punching out to 50 yards.
We have no need for loads for felling critters.
I use 200 and 240 gn boolits out of saeco moulds @ around 950 fps.
I tried some of the hbwc and it brought merit to the expression " couldn't hit a cows **** with a banjo!"
A mate tried some in his marlin and they were spectacularly awful as well.
Shooting these as cast @ approx. 0.432
They shoot fine out of a pistol.
Is this to do with the 1 in 38 twist or lack of velocity or bearing length?
I have a 41mag marlin with 1 in 20 twist I am toying with trying with hbwc when MP mould gb comes up.
