Heat treating Grizzlies

(1/3) > >>

Little John:
I was mounting some 190 grain grizzlies last night and and reducing them down with a grinder  to between 7/8" and 1" wide for greater penetration. When I went to re establish the bevel a new mill bastard file would not even scratch the grizzlie, beveled with a grinder and still could not touch up ar finish sharpening with the file. They were the hardest metal I have ever tried to work, so took them to work with me and found some insulation, heated them to a dull red with my torch and wraped with insulation to cool. They are much better and sharpen easy with the file, hope they arent too soft and bend over on a heavy bone hit on big game.   Kenneth

ZanderPommo:
careful!
most states require a minimum broadhead width usually 1 in but sometimes 7/8 i think

zeNBowyer:
I  think  that  is  one  of the  selling  points  of the  single  bevel  grizzlies,  penetration thru  heavy flesh/bone,  not  suprised they  are  tempered

madcrow:
Try to bend the tip on one with your bare hands.  If you can, they are probably too soft.  It sounds like you annealed them.  they may need to be heat treated and tempered. An Rh of 50 to 55 would probably do the trick.

Little John:
Yep Colorado requires 7/8" width, so we are ok there. ep also Mad Crow I aneealed them. Don't know how or have equipment to test the hardness, but think they are about right. Ill tell you that broadheads that are too hard to sharpen are about only gopod for stump shooting with. I mostly only shoot field points when shooting other peoples targets.     Kenneth
