Welcome from northern Quebec.
Small world - my granddaughter lives near Ottawa and her mother just told me on the telephone that she will be playing hockey in Cornwall on Sunday.
I don't know where you can find that information on building heavy aluminum arrows, I've been in the bush a lot and may have missed it because I can't remember it.
I hunt big game with cedar arrows but still shoot aluminum often for practice, stump shooting, and small game.
2419s with points and inserts coming up to about 275 grains for a good F.O.C. are my favorite for the 75 # longbow I shoot most often, and a little lighter for 2317s that I shoot out of my 71 # longbow.
They quit making 2419s so the ones I still have are precious to me - hopefully I have enough to last me until I can't shoot that bow comfortably anymore.
Years ago I would put one aluminum shaft inside another - a 2213 inside of a 2512 shot from my 93 lb. bow. I called those 2525s and the total weight was a little over 1,000 grains. It was fun!
Getting older and weaker has made my choice of equipment easier though, LOL!
