smack dab in the middle of sask!
Evening 'Nutz, i recently picked up a 99, along with a box and a half of cartridges. i realize these aren't going to last me very long, my dilemna is i can't find much for data on this fantastic cartridge. who else shoots these? does anyone have an old manual or two they could share some info from? any pet loads? hope everybody has a happy holiday, merry christmas all. Dogger
 
thanks brother rockeye, lots of interesting info there, hoping i won't have to resort to making my own brass, i did find some brass for sale on one of the sponsor's sites, they are closed over xmas, but i'll be sure to put in an order soon. what part of sask are you from??? still shooting your 303?? have a great holiday,

Sorry Dogger, that's all that P.O. wrote on the matter apart from another load for a powder that must be long gone:

150 gr. bullet
HyVel #2 powder 26 gr 1960 fps
HyVel #2 powder 32 gr 2360 fps
180 gr. bullet
HyVel #2 powder 30 gr 2265 fps
190 gr. bullet
HyVel #2 powder 30 gr 2000 fps
 
I found this on Wikipedia on the "Hercules Inc." page:
"Military Rifle (MR) # 19 was a tubular powder containing 20 percent nitroglycerin introduced by DuPont in 1908 and was renamed HiVel (# 1) when manufactured by Hercules. It was modified as HiVel # 2 in 1915. Production was discontinued in 1964. A smaller grained version was produced as HiVel # 3 from 1926 to 1941."

f.y.i. Ackey's Volume 1 was first published in 1962 when HyVel #2 was still being produced.
