today is a warm no wind day. took out my 50 cal 1/23 twist sidelock to my range west of the house. i loaded a 1.25 long swaged bullet reduced to .454 diam into orange mmp sabots. the .458 was too tight and .454 is just right. with 70 grains of black horn 209 by volume behind the bullet the groups were not as they should be. so i went back to the house and got a bunch of cleaning patches and the spray bottle of my water mix barrel cleaner. i then wiped twice down the barrel between shots and as was expected the shots from then on was very very tight both at 50 yards and 100 yards. thats all it took was wiping between rounds even with the 209 powder. most likely it is not needed with a patched round ball but with my sabots and paperpatched bullets it is, contrary to what i have posted before. i like hole touching holes accuracy and i have to wipe to get it. someone will say why the .454 diam bullet in a sabot that supposed to hold a .458 bullet. the sabots were way too tight going down the barrel with a .458 bullet in them and with the lee .454 reducing die they now go down just as they should and shoot perfectly. to sum it up, if your going to shoot a muzzleloader, best to wipe between rounds.
