i have trouble with muzzys as speed approaches 300 fps. i prefer fixed blade b heads....but have used wasp jackhammers in the past and had good luck with them.

Shewe try some magnus four blade stingers or the G5 Strikers at those speeds.

gave the slick tricks a try this past season and had pretty good luck with them. gets awful expensive switching b heads....lol. but it keeps things interesting[8D]

My bow chronied at around 178-185...but the lighting wasnt good outside that day and i have a feeling its shooting a bit quicker.

Ive spin tested them and they seem fine, im no expert but i cant see any wobble...i have a good feeling its just the combo of muzzys and my arrows that dont work at these speeds, gonna pick up the jackhammers for spring turkey

i'll bet you're a good bit faster than that....[8D]

I just may try some mechanicals, they are starting to intrigue me. Are they effective on small game as well?
Would they have enough time to open in a squirrel or rabbit?

Lol my bad...i meant 278-287....typo on my part lol just came back and read it and was laughin

You won't be disappointed with the Jackhammers for turkeys or deer with their 1 3/4" cut. You really can tie up the blades and shoot them into a target and then remove what you've tied and go hunting. If you are near or over 300 ft/sec double band them.

i had good luck using florist's wire or any real thin wire to keep the blades closed for practice.

Those little tie wires in trash bag boxes work good at keeping Mech.'s blades from opening in targets fer practice.[]
