I’ve often read how modern guns do better with certain loads due to barrel harmonics. I have a ROA and a Pietta NMA that I curiously found both seem to do better with a certain powder charge despite the projectile used.
I’ve considered sending my cylinder to Clements (or someone) to have the chambers deepened on my ROA (and NMA?) and have wondered how that might change things. Though these don’t completely fill the chambers they come fairly close in my ROA, but I’d certainly like to stretch my projectile beyond the 195 grns it is now for hunting and still leave a little room as A) another found bullets loaded to the mouths get gas cut, and B) it leaves a little room for variances with loading.
I’d prefer to keep a universal bullet for both of these. Has anyone found a newer (mines a 2013) Pietta NMA has a little excess meat in the bottom to deepen one (I’m talking enough to add just 2-3 grns worth of space - guessing 1/16” of an inch at best and possibly half that)? I have slightly more excess then I do in my ROA. I see Clements claims their procedure adds 5-10 grns (guessing in my case we might be talking 5).
