I have read thru the posts here and it does appear that feelings were hurt. If truly unintentional, I would suggest mutual appologies and letting it go. Lets try to help out on this.
I have a BC that I purchased off this forum. I have held it amorously several times, have received all of the dies and components, but have not fired a shot thru it yet. I have most of my reloading gear packed for a move. If I don't move soon, maybe I will find some of my stuff and get some loads done.
I have a Knight muzzle loader. When I first got it, I couldn't hit the target at 25 yards. Finally got a good set of fiber optic sights, used thread locker on the screws, and confirmed a good sight picture. I worked up to a load that will now cloverleaf at 100 yards if I do my part.
I have a Contender .22 Hornet that would put 55 grain bullets thru the target at 25 yards, but they were going sideways by the time they got there. Worked my way down to 45-50 grain bullets and they shoot moa with open sights out to 100.
You can get some of these "non-shooters" to group once you get the secret potion together. I don't have my 45-70 stuff available as I am at work. Here are a few things that I do recall from my research while waiting for my BC to arrive:
- BCs shoot best with bullets that weight 405 or more.
- BC's shoot best with harder cast bullets (water quenched) about .001-.002" over bore size.
- Accuracy and velocity are most constistant with a nearly full case or use of a fiber wad over the powder.
- Magnum primers are seldom more beneficial to accuracy or consistency with any of the powders used in .45-70 loads.
- The cases can stretch and it is beneficial to trim to same length and use quality crimp on some of the bullets.
- Bullet lube selected can make a difference in amount of smoke and residue left in the barrel. SPG or similar soft lube recommended.
- BC usually have a sweet spot for accuracy when velocity is 1000-1150fps and when velocity is 1650-1800fps.
- if going for the 1800fps sweet spot with 450+ grain bullets, it's gonna hurt.
I am by no means any expert on Handis. I have shot my .223 about a box and Federal American Eagle factory fodder will group in under an inch at 100. I have shot my .17HMR and can keep all shots inside 1/2 scale pigs ear at 100 yards off the bench. Handis can shoot. I expect to get my .45-70 to shoot and I hope anything I have mentioned above will help someone else to get their's to shoot.
Good luck and may your groups shrink as fast as your........well, fast!!
