Shooting Chrony-Alpha model with in-door lighting fixtures.
Thought I would get a bit more speed.Thanks for any comments.
You might try checking it outdoors, I've seen 10fps difference with my bow between an indoor unit and my Chrony outside.
My MOAB - should be very close in speed to your Bengal: 59#, 28" DL, 312 gr arrows, D loop only thing added to string from factory and WB rest: 277fps.
08 Bengal speed
Thanks dbd870.I may get a chance to try the chrony outside,next week-end.What length and brand are your arrows? I'm looking for some lighter arrows.
Has anyone shot their 07 or 08 Bengals through a chrony? I would be very interested in the results. Thank you.
08 Bengal, 29 1/2 draw, 67lbs, 406 gr arrow -indoor at 269fps.
Thanks for all the replies.I shot the Bengal through the chrony outdoors and had the same readings as indoors.Looks like the speeds I'm getting are comparable to what every one is getting.Not that fast but still a very quiet and smooth drawing bow.
Arrow Speed for 08 Martin Bengal Super Mag MPro
08 Martin Bengal Super Mag MPro, 28.5" DL, 65.5# DW, 248 grain arrow. WB rest, 2 string jax, peep sight with tube, D-loop and all I get out if it is 244 fps measured outside.
Interesting note: Arrow with only (2) 4" vanes instead of three shot 247 fps through the WB. I then rotated this arrow so that one of the 2 vanes would go through the gap in the WB and measured 251 fps. It seems that when using a WB you lose about 3-4 fps per vane to friction ( and a "de minimis" loss of weight per van).
I wonder why everyone else's readings are so much faster than mine? Perhaps the air is denser where I live? lol

Reason: added stuff
I'm hoping you meant 428gr, 248gr arrows would be about 3.7gr/lb that is risking a damaged bow. Using the 428gr arrow weight that's in the ball park. ~3fps for the WB (it appears with your long vanes it's more than that) and tube peep will cost you 5-7fps. Plus the other things on your string.
