Whats your most accurate bpcr at 300 to 400 yards

good info there Gunlaker tfs , whats your sizing procedure?
I don't crimp and only set the neck enough to take any flare out, will have to measure tension some time
 
If you guys are shooting blackpowder and just seating the bullets with no neck tension then you must be using a crimp?
Any of you guys using grease wads behind bullet?
Example melt lube in a pan. Let it cool and harden about 1/8" thick. Use loaded cartridge with a cardboard wad pressed over powder. Use loaded case like a cookie cutter to place lube wad over cardboard wad. Then seat bullet without squeezing the lube wad.
I'm just making my bullet lube out of crisco and beeswax. Mixture depends on time of year.
Years ago I was using these lube wads with paper patch bullets but I never tried them with grease grooved bullets and I'm thinking I might.
At first I was going to make homemade wonder wads but local wool felt does not exist.
Any of you tried homemade or real wonder wads?
 
Most of my loads were with no tension or sizing of cases. I would take a case fired from the same rifle, clean, prime, charge and then push in the bullet with my thumb. Shot great
 
Most of my rifles I just shoot fireformed cases with no sizing, but I when I do size cases I always use very little neck tension. Typically I anneal the cases well, then I'll size with the sizer die backed out 3 turns. Then I use custom expander plugs to expand the case mouth to either 0.001" under the bullet diameter, or right at bullet diameter. in my 45-90fof instance, I have a slip fit load with a .459 bullet, and a 0.001" neck tension load with a .458" bullet. In my 45-100 I expand to 0.458" using a 0.458 bullet. I would use skip fit in that gun, but a fireformed case won't accept a .459" bullet, and a .458" isn't quite snug enough. In my 40-65's they always shot best with no sizing.
 
Oh , one more thing I should mention. If I use neck tension the I use a Shiloh Inline seater die to seat the bullet. For some reason you don't read about these much, but they make pretty much perfect ammo with close to zero runout. Quite a bit better than my Redding Competition micrometer seating dies.
