I'm not one to take offense too often.
I have hunted with modern rifles a fair amount, and I've done fine, though 80 yds was about my longest shot, and I typically used a friend's 270 Win.
Loud booms don't do much to me. I used to do quite well with a 1911 AMT Hardballer using mostly +P loads, and I could keep them all in the black firing as fast as possible.
These loads are similar to the 44 mag with standard ammo.
I think with the 44 mag I used I began trying to compensate for the recoil and would pull, which seems to have carried on into my shooting the Old Army. I found this out with the caps not firing.
I did notice often that 1 or 2 bullets would creep out under recoil to where it keep the cylinder from rotating. I recently read that Kaido designed his 255 grn bullet especially for the ROA as it is a little larger (.460") than the 240 grn (.456" IIRC).
I chose the smaller ones as I've heard that harder bullets (his are 7-11 BHN) could stress the loading lever. Being larger too made me decide on the smaller. And Ruger states that .456" (IIRC) is optimal for the Old Army.
My Ruger's trigger seems good enough. It's not perfect, but it's not bad either.
I also don't clean it at the range. And I generally began by playing with RB's and Pyrodex before I'd swap to T7 and bullets. This very well could have effected my groups.
I'll be trying bullets first, and I suppose I ought to give it a quick cleaning between cylinders. I do carry a small water bottle, diluted dish soap, and all of the other gear for field cleaning. May as well use it and see if it helps.
I had been using 35 grns of 3F T7 with the 240 grn bullet, which was about max. I tried reducing it to 30 grns, but didn't notice much of a difference. But the gun was fouled by then...
I know I've heard many times how accuracy falls off when dirty. I guess I'm just too used to smokeless and hadn't considered it.
