Tactilever,I tried crimping at the grove making them slightly longer than recomended coal, this with 46.5 grains made a much cleaner burn! This put me at 1,410 fps acording to a friends labradar. Done a new batch with 47.5 and 48 grains. Hopefully i'll be able to reach close to 1700 fps with my 18,5" barrel.
Thank you for all your insights!
Looks like you reached the pressure needed for a cleaner burn down the barrel for the powder. Did the case seal better in the chamber? Less blow by soot on the case? The attached is a VV load manual with your powder. With a gas check bullet you should be able to reach your 1,700 fps target.
The limiting factor might be your shoulder and cheek bone. At my age the extra padding (meat) I had in my youth is no longer between the stock and contact points for me. Plus, all my levers have crescent steel butt plates!
