David,
I’ve shot several different bullets, both cast and jacketed with 22.0 – 22.5gr A2400 (Little Dandy Rotor #26). Included were 250gr Horn XTP JHP, RCBS SAA 270gr, 300gr RCBS SWCGC, 300gr Horn XTP Mag Jhp, 335gr Lyman 452651 FPGC Dual Crimp, and 340gr SST Cast TC plain base. The 300gr RCBS SWCGC was sized .454 – these are from Montana Bullet Works and are listed as 22 BHN. I did not chronograph, but all of those loads shot very well from my gun. This load (22gr+- A2400) seems to work very well no matter what bullet you use.`
I’ve experimented a little with VV N110. As you stated, it’s burn rate appears very similar to A2400. On the low side, the latest Speer Manual lists a load of 16.8gr under a 255 gr RCBS cast SWC for 914 fps in their .45 Colt 14,000 psi loads.
John Taffin lists 17.0gr VV N110 under JD Jones 340gr SSK at 1,200 fps in “Ruger Only” .45 Colt loads – he says it’s very accurate. In my 6” FA83, using .454 cases and the same bullet, I chronoed 17.5gr in . at 1,194 fps (ES 32fps) and 18.0gr at 1,224 fps (ES 23).
Using the 300gr Horn XTP Mag and 25.5gr VV N110, I got 1,506 fps (42 ES), 6” bbl. Max for respective 300gr bullets of 27.5gr in Speer and 27.1gr in Hornady’s manual both right at 1550 +- in 7 ½” bbls.
In my gun, 24.5gr VV N110 under Horn 250gr XTPs is one of the most consistently accurate load I’ve ever found. This is a 44 Mag level load and runs 1,350 – 1,400 fps..
If you are using a progressive loader, be careful w/VV N110 – I had some bridging problems in my Dillon Square Deal B.
