My No1MkIII* prefer's a milder load than my No4's. Probably due to the thinner barrel. The last time I chrono'd my loads for that rifle I was around 2380 ft per second. That was with 180 grain SB bullets and using Vectan SP7 at 38.6 grains. The No4 uses 39.4 grains of SP7 and currently 174 grain SMK's.

I need to get more time for testing some load variations for both No1 and No4 rifles; as I'm not sure that this is the best we can get. The Vectan Tubal 5000 powder was similar performance.
