yes
I had a MK I and a Marlin 25 that both loved fed eagles for about a year. both slowly turned on them now they both shoot great with other ammo that didn't shoot in them before. I am talking about the exact same box of ammo that didn't shoot before. barrels evolve. also it could just need a good old fashion cleaning. us a good quality solvent. dry it well with a bore snake then shoot a few rounds to prep the barrel and try a group.
