for years I've been shooting 100gr. spritfire for deer, so also debating if need to switch to a fix blade and also to the 125gr. for elk... is it worth going to fix blade and to 125gr. ?
Can you get your muzzy heads to shoot like your field points at 40-60 yds? I never could, they kind of had a mind of their own.
But my sons shot all of their deer from blinds with Muzzy 4 blades at close range an they did awesome!
