With 350 Barnes X--not TSX-- and 748 I get 2500 fps and well under an inch at 100 yds from my Ruger #1.

I built one long ago out of a Mauser action, for a bear hunt trip, 350grn round nose Hornaday's with 4198 powder. I have shot groups that all three shots will touch at 100yds. It has a Shaw bbl, 24" the whole gun weighs 7# no brake! No recoil pad! OUCH! The only thing this gun has killed is a "Snaggle Toothed Beaver" and several shoulders, oh and a bloody nose on a not so good friend...hehe.

I had a Savage muzzleloader. I wanted to upgrade the barrel, and I bought a Krieger 505 gibbs to replace it. Since I had ZERO experience in gunsmithing I bought a barrel from midway, a 458 barrel from A&B with a 99 ( straight 1.250) contour.
I cut it to length, I cut the barrel taper, breech and crown. A $70 investment so that I would not screw up a 350 barrel
That worked out great so now I have a cheap 458 barrel sitting around. I decided that it would be worth it to buy a Savage action and attach the barrel to see if it would shoot.
Some loads are better, and some are worse, but here is a 3 shot group @ 100 yards with an A&B muzzleloader.
edge.

80 gr of 748 215m federal match caps
JML...I get 1.62 using Hornady 350 grain bullets with a dose of IMR-4320 powder @ 71 grains. I shoot them at a velocity of 2140fps.
I also use the Barnes 450 X bullet and get groups of 1.78 to 2.35 inches. at 100 yards from the bench. These are shot at 2250fps using IMR-4320 powder.
I get 1.40 from the Hornady 500 grain FMJ using same powder again at 76 grains at a velocity of 2120fps.
At 70 grains of 4320 same 500 grain bullet, I get 1960fps and groups of 1.70 inches at 100 yards from the bench. /ubbthreads/images/graemlins/wink.gif

I have the .458 Ruger#1 with a 26 inch bull barrel. I never did do the load development to dial it in like a bench rest gun. 20 years ago I just used 78 grains of 4320 and 510gr solids and round nose soft points and 2.8X10 50 mm scope. I just dialed it to a consistant sub 4 inch group at 200 yards and called it good.
Later on I bought 500 Barnes 405 gr X bullets for horned game shooting. I was able to to get some clover leafs at 100 yards on the bench shooting them right at 2400 fps. Very deadly round. I don't think that sub 1000 pound animals would stop this bullet in under 250 yard shots
