The .223 WSSM
 

A co-worker and his brother both have Winchester Model 70 Coyote's in .223 WSSM. He says they haven't been able to achieve much accuracy with the handloads they have tried. He did say they haven't tried any bullets over 55 grs. though. Do any of you have a .223 WSSM and what has been your experience with it? I would appreciate any info you can give regarding powders/bullets that have worked well for you and I will pass it on to him. Thanks a bunch!
