I was out this morning testing some different conicals I had on hand out of my GM 29" LRH. And to try different charges.
Targets were set up at 50 yds, 63 degrees, overcast.
Upper left target: My very first shot I pulled while 'settling in' to the bags. After that I fired 3 shots of 90 gr Pyroxex RS, Wonder Wad, and the 275 gr Maxihunter swabbing between each shot. Not very impressive. Just to see if it was me, I dropped back down to my original 80 gr load of Pyrodex RS, wonder wad, and 275 gr Maxihunter. The group 1 /12" high at 12 o'clock is 3 shots - in almost one hole.
Upper right target: Same 80 gr load of Pyrodex RS with the 350 gr Maxihunter - totally sucked.
Bottom target: Again, 80 gr Pyrodex RS, wonder wad with 320 gr MaxiBall. This isn't too bad and deserves some more tinkering. But I only had 5 left so I have to get another box.
Its fun to play around but I don't think I am ever going to improve on the 275 gr Maxihunter load.
