first off i think im going to change my girlfriends broadheads, from a 85 grain, 4 blade. to a 100 or possibly 125 grain cut on contact head. here is where i would like some suggestions. we hunt whitetails, shots will be 0-40 yards her bow is probably 15 years old, 40 pound draw weight 25 inch length, and it is a pretty slow bow. her arrows are 26 inch and 9.3 grains per inch. do you think she should get 100 or 125 grain heads or stick with the 85? its definetly going to be a cut on contact, but not sure how heavy i should go. for me, i have been shooting 100 grain muzzy mx-4 and have never really had any problems but am considering getting a cut on contact head, with a larger cutting diameter. but i am thinking maybe im just over thinking things? i feel like i need more cutting diameter the main answers im looking for here is what size for my girlfriends bow, but suggestions for everything mentions are welcome.
100 grain and keep her shots under 25 yards. I dont believe an old bow at low poundage will have enough KE or Momentum for much past that.
I agree with ncnat, I'd keep her shots to 25 yards or less with that low poundage. Remember also if you change the weight of the broadhead, you might need to change the spine of your arrows. If her arrows are shooting good now and flying straight, I don't think I'd mess with it. Some bow/arrow set ups like a certain weight broadhead and perform best with that weight. Then again you might actually improve the performance if she is having problems with her arrows grouping together. Go to an archery shop and ask if you can try shooting different weight broadheads to see which one works best out of her bow.
Yeah, what they said. 125 I think will be too heavy and there isn't enough gain from an increase of 15 grains. Keep em close and put em where it counts. 85 grain Magnus Stinger will do the job 'sho 'nough.
I'd stay with the 85 grain since she shoots such a low poundage with a older bow if it aint broke don't fix it
well we went ahead and went with a 100 grain steel force 4 blade,( 2 blade with the small bleederblades) i told her a two blade would be better but she wanted the four blade. we shot it at 20 and 30 yards and it seems to shoot just as good as her 85 grain fields tips, but has more penetration (in the target) thanks for the replies guys, her first hunt, and first kill two years ago, was a doe at 30 yards, and her arrow made it all the way in but barely didnt come out the other side. im hoping with the added weight and cut on contact she will have pass throughs, if not atleast better cutting diameter.
