I have commissioned one of your fellow citizens to produce a 375 H+H barrel for my Blaser R8. I sold a ripper JM 444 to fund the purchase of this rifle and want to have a barrel specifically for brush hunting Sambar Deer with cast. They are big suckers and 338 win mag is a favourite calibre for these ferals.
I am curious to hear your thoughts based on real experience please. I have a 235gr Noe GC mold which will get me started and would be delighted if I could get these up to 2500fps. I have the option of 1:18 twist and 1:14 twist. As I don't need to shoot more than 300 yards and probably 250gr max boolit weight I am tending to favour 1:18.
I have had a twiddle with JBM ballistics stability but like to hear real life opinions from some of the people whodunnit. Thanks in advance, JIM
