DLH Posted October 24, 2015 Report Share Posted October 24, 2015 Anyone shoot this cartridge? Link to comment Share on other sites More sharing options...
gbal Posted October 24, 2015 Report Share Posted October 24, 2015 Probably not many! First appeared in 2003, it's the 6BR necked to 20,slightly longer/wider body,and therfore shorter 45 degree neck. This gives about 10% more capacity. Not clear what it really does that a 20 BR doesn't,but you have about 500 rounds barrel life to find out. That probably accounts for its rarity,but if you are currently shooting a 5/35 SMc and therefore need a rebarrel even more urgently,it might appeal. :-) gbal Link to comment Share on other sites More sharing options...
Alycidon Posted October 24, 2015 Report Share Posted October 24, 2015 My 20BR is still shooting well at about 800 rounds. A Link to comment Share on other sites More sharing options...
DLH Posted October 29, 2015 Author Report Share Posted October 29, 2015 I got one made in around 03 but put things got put on hold for one reason or another and so was wondering if anyone had done any work with cartridge in the mean time? Seems I'm on my own! Link to comment Share on other sites More sharing options...
Alycidon Posted November 6, 2015 Report Share Posted November 6, 2015 Just go 20BR and dont look back. Vermin then tube it for the 39gr SBK, ultra long reach then the Berger 55 gr, A Link to comment Share on other sites More sharing options...

Seems I'm on my own! I have a 20BR and I shouldn't imagine load development for your Ace will be that much different. What twist rate do you have and what bullets are you shooting? I have found 29.7gr of N133 and 33.5 gr of N550 work well with 39 SBK's and 31.1gr of N550 with the 55gr Bergers, the Bergers are jumping 0.150" and the SBK's about 0.120" A lot was said here about N550 burning my barrel out quickly but I had it scoped recently by the gunsmith who built it and at 700 rounds he said the wear was minimal, he felt that the barrel looked around 1/3 of the way through its life if it was maintained and shot sensibly. I never fire big strings, usually its one shot at a time and the barrel never gets detrimentally hot. Link to comment Share on other sites More sharing options...
