i went to cabelas tonight and picked up some good ole muzzy 100 grain 3 blade heads. by the way, i've blasted through front legs too. on more occasions then i should probably admit.

rob - i hope there's no difference in them. i'll have to look through my collection. i have 90 grain, 115 grain, 125 grain, 100 grain (3 and 4 blade)...some are 12 years old.
