Vermonter,
That is a stout load to be sure. I have studied tripple seven and found that due to the way its made, it will produce a moist fouling that acts as its own lube. In fact, if you need to clean the bore while shooting, something is amiss. I am still amazed that the lead fouling came out with conicals. They must have some special lube on them that will defy lead!
Had an ROA back in the mid 70's that was a real shooter. Never fired anything but conicals as that was the mould I found where I was at the time. It sure was a good weapon, but like an idiot, I traded it for something else. Kept my colts and remingtons. Musta been in my "I gotta have authentic looking guns" mode then! Boy was that a dumb idea....Miss that ROA now to be sure.
I hope you have many fun days with your pistol. Look forward to more on your progress with it in the future...
Wade
