Question: do the blades fold up aand stay or do u have to use a o ring type? and do these work in crossbows ?
Document: I like the shock collars much better than the old o-ring system Rage had. I shot my first deer with this broadhead this year. Shot a 10 point - made a bad shot (due to problems with xbow scope). Hit the femoral artery below spine. Rage did the job.
took out 2 deer this year with these, A good shot both times & the deer went no further than 75 yards either time. excellent broadhead
Turkey hunted with these broadheads last Thursday. It was rainy and 47 degrees during the hunt and the only bird I saw was a 3 year old gobbler. At 27 yards, I took the broadside shot and the gobbler went 10 yards after the pass through shot and died. The broadhead worked perfectly. I highly recommend these Rage broad heads.
This product is sold in 3pack. Two Broadheads in the pack were perfect.They shot accurate and hit hard. the other one was missing the set screw and the cutting blade fell out .Never did find it.
They are a little bit pricey but they're worth it. Every pack gives you a practice tip and I think that makes all the difference. The practice tip is identical to the mechanical broad head but it's just &#34;fixed&#34; to where in won't open. Oh, and it's blue. Since changing over to the Rage broad head I've never lost another deer and the longest they're ran was about 30 yards. Highly recommend! It'll change the way you hunt forever! It did for me!
No joke! The first deer I shot was right at 20 yards with my &#34;fixed&#34; broad head and it ran about 100 yards and died. The next 3 deer I shot at with my &#34;fixed&#34; broad head I was unable to find due to running so far and losing blood trail. I never shot over 30 yards for any of these deer. That's when I hit my hunting low point of my life.
I'm an avid hunter and have used a lot of different hunting supplies. I started off using &#34;fixed&#34; broad heads and had a lot of trouble with them. First of all, you can't practice with the mechanical broad head. It will ruin them and your target. I bought field points that matched the grains of my &#34;fixed&#34; broad head and was dead on the bulls eye of my target.
I inspected the product upon it being delivered. They look awsome. I have never used a mechanical broad head befoe but upon inspecting these I think I should have started a long time ago. Thank you Rage.
I firmly believe in eating what you hunt and it made me sick to lose those deer. After losing the 3rd deer I decided to shoot a &#34;fixed&#34; broad head into my target. I was shocked at the results. It was about 8 inches low and about 3 inches off center. I shot another and same thing.
Heard a lot of good things about these broadheads and found out first hand how lethal they are after killing a 9 point buck hit him broadside at 30 yards double lung shot arrow passed completely through deer he barley trotted another 25 yards never got out of eyesight before expiring....i'm sold!!! !
