6.5 GAP 4S/6.5 SAUM LOAD DEVELOPMENT

[SS GO DEVIL]

Well I had a 24'' .264 8 twist carbon fiber wrapped barrel that needed a home. After researching I decided on 6.5 SAUM .298 nk .80 free bore installed on a zermatt bighorn origin action. It's going to be my dedicated long range hunting rifle and was hoping to shoot 130-140 nosler ballistic tips in ADG brass with H1000. Any pet loads recommended? I obviuosly will work up to them in a safe manner.

My pet hunting loads are Barnes 127 LRX jumped 0.020" with RL23 @ 3290 fps and the Berger 156 EOL with N570 at 3210 fps. H1000 is supposed to be an excellent powder for the SAUM but these shot so well that I never got around to trying it.

Still working on mine, but 60.0 grains of H1000, 140 Hornady ELD -M , CCI250 in Rem brass is looking very good. Start around 57 grains and dial it in. Start low as many different throat lengths are available and can and will reduce case capacity. Good luck and keep us posted.

127 gr LRX x 62 grs RL-26, RL-17 works great and 1000 will work. The LRX is by far the best bullet, I'm on #4 Gap/Saum now. RL-26 load will get me 3225 from a 20 in barrel, my bud is getting 3425 from a 24 inch tube. EXCEPTIONAL accuracy as well. I have a barrel in the lathe that is getting the Gap/saum reamer and one on standby. Quite a bit of experience with them.
