.40 cal conical ?'s

My Super 91 .410 White has a measured .4095 bore and came with .409 White Super Slugs . Ive shot them from the original .409 to 4.115 kurled up using BLL , Bills Liquid Lube , showing the best accuracy with a dry 45 wool wad .
The powder & lube used will determine alot for the fit used im sure you know . My preference or rather the guns is 4.092 to 4.093 for the best that button rifled Wilson barrel will give me using BLL LUBE . Just 1 drop will do a bullet just wet then let it dry . Crazy thin !!! This stuff is claimed to hold up to 2500 fps from a cf !!! I Never got lead in my barrel .
Modern Muzzleloader has the recipe as well as online on google . Theres a few different ones !!! I use the MML formula .
My twist is 1 in 16 and i shoot 400 gr 40 to 1 conicals 99% of the time . 95gr of T7 3F packs one heck of a wallop to finish its load . That load will also get you out there beyond 250 yds pretty easy with authority should you need it . Any deers shoulders will be busted and complete pass thru too so far to 135 yds or so . Hits HARD .
Id try Bullshop if youre gonna buy bullets . Good luck !!!
Doc White had 3 bullet weights for his 410s . A plinking 280gr and deer hunting 330 to just barely 200 yds and the 400 gr for bigger criters including elk !!! All with 80 gr suggested of Pyrodex P .
The 400gr would get 1310 fps with 80 grs and 200yd capable at just about 1100 ft lbs .
T7 3F is Alot more powerfull powder .

Well its been a while since i posted. I got tired of waiting on my build barrel n ordered a .40 with a 1:48 13/16" 32" barrel. It will shoot the prb n conicals fine. I got moved back to Mo. My built barrel came finally. Now i have 2 .40 cal barrels. I took the whole rig to a Gunsmith friend here last Sat. I had scope mounts thimbles underlugs for forearm on the light barrel. Have lugs for other barrel with pins to attach forearm n ramrod. Just waiting now, i will mount scopes n work on it as i use it to hunt with this Fall. I will use the T7-3f powder with wool dry wads.
