Heavy broad heads.

[ultra man]

Hi all, I'm pretty new here, but have been reading for a while, and would like to thank you all in advance for the great advice I've received while reading your posts. My question is this... I shoot a Ten Point Pro-Fusion, and currently use 100 gr heads. I saw some broad heads in, I believe Cabelas, that were very heavy, if I can recall it said they were upwards of 170 grs. Is this common practice in crossbow hunting, to use such a heavy head? Does it compensate for shorter shaft length, etc? Forgive me if this has already been discussed.

a lot depends on the arrow you're putting them on......but, that's an awful heavy bhead. i think you'll be happier using a lighter head.....say 100gr - 125gr.

I have saw some of the heavy B'Heads, just have to make sure it sighted in and they group well for the range you hunt game at.

The weight of the head can change the spine of the arrow,it would take a very heay and stiff arrow too get the best accuracy with a 170gr broad head. Elephants per chance? Lee

I use them for elk (but also for deer and I'll even keep the same setup for pronghorn). This will sound crazy to some on here, but I use a 125 gr. Zwicky 2-blade BH glued to a 125 gr. steel adapter to bring the BH weight to 250 gr. This gives me a total bolt weight of 650 gr. with 2219s(good medicine for big elk ribs) and they fly fine. I haven't had any trouble with the flight and I don't really notice flight differences from changing spine. I have shot 100 gr. heads and 250 gr. heads with the same bolt/ crossbow and they both fly fine from my crossbow. Definitely not needed for WT deer (or the muleys I hunt here in Colorado), but for elk, I'm learning that I always want heavy and for me that means at least 600 gr. Another thing that I've noticed with heavy bolts. I did a test a while back to see how much different shooting a 400 gr. bolt and a 650 gr. bolt would be. I shot using one pin set at 20 yds. and shot at 15 and then at 30. With the 400 gr. bolt- the impactdifference between 15 yds and 30 yds was 9". With the 650 gr. bolt, the difference was 11". Adding 250 gr. only made a 2" difference at these yardages. I think maybe at longer distances (50 yds or so) it might make more difference, but for my hunting situations, the advantages of a heavy bolt far outweigh a slight disadvantage in range limitations. As far as your question, 170 gr. isn't too heavy as long as it flies good from your crossbow.
