I just bought one of these off another forum. Should be here by the end of the week. I have couple of 50's but no experience with this large of caliber. Anyone used one of these? Anyone recomend ball/patch size? I have always shot PRB in my 50's but was thinking about a conical for this beast. Any advise? I am not even sure of the twist in this barrel but the price was right and I coudn't pass it up.
Since you asked I'll give an opinion...I have a .58cal GM barrel in a TC Hawken stock and the .58cal is an outstanding caliber...the big 279grn ball will take most anything on the NA continent.
Let me repeat that to ensure it's clear: the big 279grn ball will take most anything on the NA continent.
You really, really, really do not need to punish yourself with a huge, heavy recoil, rainbow trajectory 535grn conical...if you decide to go after the big bears way up North, then get a couple boxes of .58cal Hornay conicals...which by the way are also very expensive.
But otherwise, I promise you'll find the .570/279grn round ball to be totally lethal on anything else you'd hunt in the US.
And 1:48's shoot RBs extremey well...even just a mid-range powder charge of 100grns Goex 2F will make complete passthroughs on every eastern deer and it's devastating on them...carries energy to long distances as well.
Note: the Big Boar just has a single manual trigger...does not have a set trigger.
