[QUOTE="BEEMAN, post: 1001030, member: 38130"] I just got a model 52 Cooper 280AI Jackson Hunter. After measuring to see what I could load for a COAL; I found that I can't even load to mag length. I am wanting to shoot the 168 Berger classic hunter bullet. When loaded to mag length I would be .151" into the lands. I can only load to a COAL of 3.244" which is just right at the lands. Also the Redding dies are almost out of adjustment because we have to seat the bullet so deep into the case. I am at 57 gr of H4831sc and it will be compressed soon. Are all the Cooper 280AI chambered like this? Seems weird that they would offer a 1 in 9 twist and not chamber it for long heavy bullets. Any help is appreciated. Thanks. [/QUOTE]
