Shot the Precision Rifle 450gr Ultimate 1 and No Excuse 460gr conicals at the range today. Used 777 loose powder, Winchester muzzloader primers, and TC # 17. (yes #17) Prior to shooting today I had given the Omega's bore a very good cleaning followed up with JB Bore Paste and then JB Bore Bright. This gun has not had many bullets through it and I thought the JB products would help smooth things up a bit and make sure the bore was absolutely clean. Useing 90grs and No Excuses: 3 shots 1 1/8" @ 50yds, another group 2 3/8" @ 50yds, and 2 shots into 3 1/4" with the third shot opening it up to 6" (me) @ 100yds. Useing the Precision Rifle bullets about 12" @ 50yds. The Precision Rifle bullets load extremely, extremely hard and didn't shot very well the first time I tried them ( could have been the pellets the first time?) and after this group I quite with them. They are just so hard to load, I'm not going to fight to get them down the bore. When I got home I measured the Precision bullets .510" OD. I measured the No Excuse bullets .503" OD. Might explain why the Precision bullets were so hard to load. I'm going to call them tomorrow and ask them why are their bullets .510" OD ? I'm pleased with the No Excuse bullet. At this point I think I'm about at the limit of how accurately I can shoot with the Williams peep and that red fiber optic front sight. I really don't like that front sight. It makes it very hard to do precision shooting. I would prefer a post front sight. I used to shoot highpower rifle matches, service rifle so I can shoot peep sights. It's just that fiber optic blocks out what you're trying to shoot. Anyone have any suggestions on a different front sight? I'm thinking about putting the scope back on it just to see what it's really capable of at 100yds then putting the peep back on for Colorado. One other question - the No Excuse bullets go down the bore almost like Power Belts. Very little resistance pushing them down the bore. Is that how conicals are supposed to be?
