Well im shelving this project for a bit as i can still out shoot my slug barrel with my pellet barrel! I have to get ready for upcoming hp ft matches so i must dial the gun for pellets.
That's a trend I've seen as well. Last count was around 40 barrels that I've tried slugs out of, most of them .22s but some .177s and .20s in the mix. And in only two instances has a slug/barrel combo been better than pellets.
Even the blasted .22 MRDs with their cursed flyers....I've got 4 barrels on hand right now that'll all do 10 shot groups that hover around 1.75-2.25" at 100yards....even that's better than the typical 100yard group from slugs from 98% of the slugs/barrels I've tested.
