Thinking about rocket aerohead expandables. can you trust them , are they that good at bringing down game , and how do you practice and check your pins with them?

I dont trust any type of expandable
except for maybe the snipers.

aimatdeer:
This question will no doubt bring a bunch of responses about the merits of expandable vs. fixed. I for one shoot fixed, but I do know that there are many reliable expandable heads that will bring down game just fine. I've never shot the rocket heads, but to sight in any head, you have to sacrifice one of them and just shoot it at any target you normally shoot at.
Hopefully, someone else here can tell you more about the Rockets.

Good luck with your changeover!

Some are excellent and some are junk. Some work great with only higher Kinetic energy setups, some will work well with Lower KE setups. It really depends on what your looking for and your setup. Rocket heads in general are good. They fly well and open quickly. The blade sharpness should be better however. Practicing with mechanicals can be done, and depending on the model you can use dental floss to tie down the blades. It's really hard to answer your question without knowing first the heads your interested in, and then what the specs are for your setup. Draw wieght, length, arrow weight, speed, bow make and model etc. You can visit my website www.broadheadtests.com and get some info but we really need to know more about your setup before we can offer good advice.

if you have any doubt in your mind , if a mechanical will work or not, then you should not use them.

Mechanicals will work, better, out of a well tuned bow. for setups with KE in the 55 ft lb range don't go any larger than 1 1/4 inch cut.
A two blade offers less resistance than a three blade therefore a two blade should penetrate better than a three blade.

Like any other broadhead they will not make up for bad shot placement.

Most stories about mechanical broadhead failure is bad shot placement, even though the teller of the tale will deny it.

My son took a 15 yard shot from a treestand at a 7-point buck on Wednesday using the new TEKAN from Montec. He said he could not believe the damage to the heart and lungs. The buck dropped dead 25 yards from his stand. This is the first deer he killed using any kind of expandable as we have both had success in the past with the Montec G5.

I shoot a 370 grain arrow at 286fps...total of about 67 lbs of KE.

I had issues with the Bigger fixed blades that I've used it he past...planing and wind shearing all over the dang place. I could shoot field tips and shave fletch at 40 yards....My Stingers corkscrewed down at 20. Snuffers were 7-8" in any direction but never in the same spot, Muzzys were a little better but not much.

4" offset feathers...I went with a compact head. Rocket Ultimate Steel in the 75 grain. 1" cut and shaving sharp....mean looking little things.

Everything I hit I blow waaaay through.....problem is lack of blood. Hole's to small for my liking. Everything's died within 30 yards or so but I've made good shots and heard or seen them fall. But blood even na double lung with a low exit was scanty at best.

I need a bigger cutting diameter.
Enter the Rocket Wolverine. 75 grains (didn't want to have to resight at all...middle of the season here) and 1 1/4" cutting diameter. Amazing how much a 1/4 " can make. Blood everywhere and spewing.

Only shot one with them so far but but they fly great and did what I was looking to the to do so....

I switched from 125 thunderhead fixed blades to 125 spitfire mech. The deer I shot with the spifire put a 3 inc rip in the exit side and pieces of lungs and meat were hanging out and all over the ground.

I won't trust one myself. They have not been out long enough to prove themselves. There are so many decent fixed blade broadheads today I can't see why anyone would need them. If your getting poor arrow flight - I'd work on that first!
