Hi Mike

I hope you did not mind me using your pic of the Stephen Grant for the rebounding and non rebounding locks thread

With regard to your comment about the rifle being originally a .577 Snider, Hoyem does not give a start date fo the .577 3" so my initial thought was that you were correct with such an early rifle

Bill Fleming does, however give a pre 1874 date, possibly for the coiled brass cartridge

I have attached the relevant pic for your info (Thanks and credit given to Bill Fleming) if you want more, let me know

I have an 1877 Williams & Powell in .577 Snider, as well as a .577 3" by Hollis

If you choose to use the 4198 load please ensure you USE MAGNUM PRIMERS!, I did not on one occasion and had unburnt powder everywhere and a bullet stuck up the barrel!

At 8 lbs 4 oz you will certainly know you have fired it, (with a standard load of 160 grains of powder behind a 560/590 grain bullet!), your intention to start light is good, but be aware that reduced loads refer to lighter bullets, not less powder

Good luck with your endeavours, care with the 4198!
