Hi Im new to this forum so I hope that I'm not being redundant. I have one of the earliest models of the Savage ML one of the ones with an extremely tight bore..... I have been shooting this rifle for years with extremely good accuracy cloverleaf groups at 100 yds were the norm. I shoot a 250 gr FTX bullet with an MMP black sabot and 41 grains of N110. I have changed nothing but my accuracy has deteriorated now the first shot is right on the second about 4" off the third about a foot off and the 4th completely misses the target board. I have changed the vent liner and the breech plug at Savages suggestion. No help, I even sent the rifle back to them and they sent it back with a target showing a 4-5 inch group. Id really like to figure this out anyone have any ideas out there thanks
