A word of caution on the pistol primers. Powders on the slow side of H110 may not respond well to reduced brisance (except IMR 4198 and RX-7, but NOT excepting H4198, XMP 5744 or AA 1680) due to the nature of their deterrent coatings.
Where I see the most benefit of reduced brisance with low-node stuff is with flashy powders like Bullseye and Titegroup in case sizes up to .30-'06. I know Ben uses a lot of Red Dot and similar in .35 straigh walls, .30-30, '06, etc. and has also found an accuracy advantage to pistol primers in these situations.
