RE: I'mmmmmmm Baaaaaaaaacccckkkkk
Well I went to the shop and shot for about an hour or so. I was a pretty miserable sight to watch for the first 20- 25 arrows, but then I started to get back in the groove a little (was canting the bow and rushing the shot at first). My last group was 2 of the ICS stacked neatly on top of one another on my point of aim and 2 more stacked the same about 3/4 of an inch directly above them. I learned (the hard way) to make it a point to quit shooting when you are happy- positive reinforcment is the best thing in the world. I knew if I kept shooting my groups would open up as I got tired and then I'd be miserable. So I packed up the bow and shot the bull with the guys, ran the bow through the chrono, checked out some other bows, helped a customer, etc.
I was a bit dissapointed in the speed at first, but after I got to thinking about some of my past setups (heavier peak weights with similar weight arrows), I realized everything was good.
GT500- 62.4 pounds- measured the the draw at 28.75" AMO-Brace height is 7 1/8", 80% letoff- ICS Hunter @ 386 grains (weighed) shot 279-280 FPS. Carbon Tech Cheetah @ 308 grains (weighed) shot 311-312 FPS. Loop and G5 peep on the string. Stat card said bow would shoot 300 grain arrow at 314-324 so it's on the money spec-wise though at the low end of the range.
To put that in perspective-
My Mathews Switchback shot a similar weight arrow (385-390) close to 29"AMO (28.5" cam) @ 291 with loop and peep. It was also on 72 pounds draw weight. 7" brace.
My 62-63 pound Extreme VFT with 29" module set to 65% letoff (was a little over 29"AMO set that way), loop, peep, shot 388-ish grain arrow (ACC 3-49), at 274-275. Brace height was 6.5"
So I doubt the GT500 will hit those top IBO speeds they claim (346 FPS), but it's still a quick bow, 330-335 would probably be more realistic. The best part is its QUIET and vibe/recoil free. Even @ 5 grains it was pretty quiet and I still didn't feel any vibe. Very pleasant to draw and very pleasant to shoot. Kevin seems to have finally pulled it all together- speeds of the old BK cams with a FAR better draw and noise/recoil/vibe levels of the better single cam designs.
Also, I did draw the Allegiance they had on the shelf- noticeably nicer draw than the Captain,Admiral, etc.
