Hopefully someone else has experienced this and has found a solution. Last year Utah allowed magnifying scopes during the muzzleloading season. Prior years I had used Nikon Bucknaster 1x scopes on many of my smokepoles.
Last year I put a Vortex Diamondback 4x12x40 with a BDC Reticle on my White S91 .504 I just traded a chainsaw for this rifle and know the man I got it from very well as I had advised him to buy a White for his upcoming muzzy hunt the year before, and helped him get bullets etc.. I had seen pictures of the groups he had shot from it, 2” at 100 yards with a 1x scope. Shooting it this year with the Vortek, I can’t get better than 4” at 100 yards, with most groups closer to 6”. Shooting the same No Excuses 460 grain bullets. I have tried loads from 60 grains through 110 of Pyrodex p and also Pyrodex Select RS. The only difference between what we shot was he used ff T7. I haven’t tried that yet. Bought some yesterday but haven’t gotten out yet.
I’m having the same issue with my .451 s91 last year groups of 1.5” to 2” at 100 yards using 385 grain NE over 60 grains of fffT7 and same results with 460 grain NE over 90 grains fffT7. Put a Bushnell 3x9x40 with BDC on it and groups went to heck. I did run out of T7 last year and have been trying Pyro p and select RS. Could the T7 make that big of difference?
I suspected maybe leading or something along those lines and scrubbed the crap out of the bore. It looks like a mirror inside. I usually run a windex patch back and forth in the bore and then follow it with dry patches pushed all the way through and out the breech. Lastly I double a patch and push it through a couple of times and it fits pretty tight. I noticed that while pushing the double patches, the bore gets a little more snug closer to the breech. I can’t imagine these barrels are “shot out” yet they are a little looser as you travel up and out the bore. Gonna try T7 this weekend in both rifles this weekend and, hopefully it’s that simple. Any body else run into this. I slugged both bores and using a micrometer, not calipers, got .4515 on the .451 and .5038 on the .504 but I pushed both slugs all the way through. I probably should have pushed one all the way through and then pushed one halfway down from the muzzle then pushed it back out to check the difference in muzzle and breech. Anybody else run into anything like this?
