i woudnt normally advise on loads but the m1899 is a bit of an odd one which i have first hand knowlege of.first off this is a loading i have used with no ill effects many times but use it at your own risk..10g of titegroup over a 180g gas checked 303 bullet [.311] worked very well for me at 100yards.titegroup was developed for small loads in large cases but work up slowly looking out for pressure signs up to 10g in increments.tried .308 bullets but accuracy was unacceptable.hope this helps,if i remember rightly the original 1899 loading had simular ballastics to the 30-30 round.i think 2200fps was the speed of the original m1899 round.cheers greasemonkey..
