    Hey guys, I'd appreciate any info on the subject. Years ago I won a barrel of my choice from Douglas and I had a 243 Ackley Improved chambered. The barrel is 26" and 1in10 twist.
    So far I've not had any luck on bullets above 85gr so I'm sticking with 80gr Bergers or Sierra. It's been awhile since I played with this gun and didn't want to waste any more barrel life. If you know of a secret recipe (powders) that works with this please let me know. Right now the load I've been using is 80gr Bergers and 47.5 R19 It shoot around .5-.75 (5) shot groups
    Thanks, any info would be appreciated

    I would try some 100grn Sierra SPBT. I know my 1:10 Model 7 shoot them okay. If not, then try some 87grn Hornady V-max. H4350 seems to be a popular powder for these weights, but you could try some RL17. I use 37.5grns 4064 w/ Hornady 95grn SST's. I would think you could push them fast enough to negate the necessity of a 1:9twist for 100grn bullet.
