I do in fact shoot them.
Mind you I've only been shooting them for roughly two months now, but so far I love these arrows.
When shopping for arrows when I purchased my Allegiance I wanted something on the heavier side that would still shoot relatively fast. I told myself if I could shoot a heavier arrow at 275fps or more I would be happy. Completely set up, my 27-inch arrows fitted with 7" wraps and blazer vanes weigh 427 grains. Each arrows is +/- .5 grains of each other. Now, I haven't shot them through a chronograph, but using a tool I found online my71#Ally should be spittin' these arrows downrange at 276fps with 70.1# KE. With my relatively short draw I'm happy with this combination of speed and KE.
I also really like the Slim technology incorporated into these arrows. I shot them into my Morrell Yellow Jacket field point target aside my old Gold Tip XT's and the FMJ's penetrated about six inches more.
The only problem thats arrisen so far is I hit an insert that fell out in my target and it dented the alluminum shell. However, after shooting this same arrow several times since then it shoots no different than the other five and still groups with the rest.
Look at them as an inside out A/C/C with a slimmer design. The straightness of alluminum with the durability of carbon; you can't go wrong with these arrows.
