Hi l have a Parker Ambusher crossbow and was wondering about the kinetic energy and the speed with the bow set to 135lbs draw weight versus the 160 lb draw weight. We will primarily be hunting hogs and deer with the bow. Do we need to turn up the draw weight for deer and hog. Manual say it 315 fps is that at the 160lbs draw weight and is it a lower speed at the 135lb draw weight, and if so what is that speed? Plus will it be harder on the limbs at 135lb draw weight versus 160lb draw weight. We will be using 400 grains or 425 grains of arrow weight. Any answers are greatly appreciated.

Best thing to do is find somebody with a chrony and shoot your arrow thru it to see what it's doing. Good luck.:)

That would probably work pretty well. I just dont know anyone around with one. l have been looking all over the internet for some technical information about the bow but its darn near impossible to find anything. You would think Parker would have put it in the manual or would have published it somewhere. I just wasnt sure if the speed was the same at 135lb draw or 160 lb draw. I would think the more draw the harder and faster it would hit and that is their advertised speed. My 10 year old will be using it for deer and hog. Plus from what l have heard Parker had some limb trouble so if it's better on the limbs at a lower draw weight and it will do the same then no need to up it to 160lb draw. But heck what do l know not much. Lol. Thanks for the reply back.

The different weight limbs does dictate a faster bow with the heavier limbs (slower bow with lighter limbs). I'd heed the advice that Robertyb gave you though as there's no fix if you break 'em now that the company is gone. Find an archery shop or bow range and you'll probably find a chrony you can shoot thru.;)

Thanks for the replies. I think l am going to just leave them set at the lower draw weight to avoid (hopefully)any problems. I bought 2 new Parker Ambushers right before they closed and got a really good deal on both. I also bought 2 of their box packs with extra arrows and accessories. So 24 total arrows and 6 broadheads. We didn't even get them out until here recently. Then l was thinking l should have bought some extra limbs for both of them before Parker closed. But l didn't. I should have called Parker and got the specs back then but time passed and l just got busy. I have an Excalibur Vortex and Bear ffl so if the Parkers blow we are out a little cash but my son and l have the other bows to use. I like the Parkers because they are small and light but it looks like they had limb issues. We will see how it goes. We will probably only use them for deer at a max of 40 yards. So the lower weight will probably be just fine. I was hoping someone knew how about how much energy was produced at the lower draw weight. I guess a chrono test will be the best answer. THANKS.
