What kind of accuracy can I expect from an older Ruger 77 in 257 Roberts that has been unaltered from the factory, and has not hardly been shot? I just got it in the mail from a purchase on gunbroker. The gun is immaculate but my first impression is that the barrel is a bit light compared to an older Remington ADL in 243 that is right beside it. The wood to metal fit is very good but I can't decide if I should float the barrel before I shoot it, or wait to see what it will do first. I'm going to sight it in with Hornady Light Magnums with 117 grain SST bullets this morning after I get done pushing snow. Any thoughts would be appreciated. Thanks.
