Those prices are precisely why I buy a bow that is one year older, for instance, next spring you could get that same $1,000 setup for $500. But, I really do appreciate you taking that $500 "new" bow hit for me

You think it would be higher than 263 fps nub?

Double Creek

Josh, that does seem low to me as well, what grain arrow are you shooting?

At 73lbs and 29inch draw, I would expect MUCH more than 263.

Pse Carbon Force Hunter 300 arrows...not sure on the grains..cant find the specs anywhere. but I believe its around 8 grains per inch.

29 x 8 = 232 + 100 grain tip = 332 + 65 grains (approx) for vanes, inserts, and nock = 397 grain arrow.

string loop, hush kit, kisser, and fletcher tru peep on the string. Also shooting a drop away.
The birth certificate says 289 fps with a 350 grain arrow at 70.5 lbs...however, at the shop, it registered at 73 lbs on the scale. any guesses?

I hope I am able to get a deer with my measly $325 PSE rig???

Congratulations on the new bow Josh. However, I am sure there are some guys on here that are thinking that they could have bought a new beater pickup for that kind of money....


That speed would coincide with what I am getting out of my Liberty. I have been doing some rather exhaustive testing with both the Liberty and MM to see how they handle various arrow weights.

With a 30 inch draw length, 71 lb draw weight and a 418 grain Beman ICS 340 I am getting around 269 fps with the Liberty. With a 360 grain arrow I am getting around 288 fps. My string accessories seem to be costing me about 11 fps off of the bow's BC rating of 302 fps.

Hmmm, that is strange! Maybe I got a fast one! My Liberty's b.c. said 71#, 29.5", 350 grain arrow at 299 f.p.s.

With my bow set at 71#, 29.5" draw, factory set up string (hush kit, nock, eliminator buttons) and a fletcher tru-peep!

430 grain arrow at 275 f.p.s.
405 grain arrow at 281 f.p.s.

Jason,

My peep sight is a medium sized Shurz a peep which is somewhat heavier than the True Peep you are using. Also, I would be willing to be that the string loop/tied-in nocksets combination that I am using weighs more than that brass nockset you have on the string....

That is about all I can come up with but it is verified on 3 different chronos now.

However if you do the math....

...and add another 5 fps onto your BC because of the half inch shorter draw that would put the base speed up to 304 fps. That is 2 fps faster than mine.

Subtract 2 fps from your 430 grain arrow speed and that gives you 273 fps. A 12 grain difference in arrow weight (418 vs. 430) should equate to about 4 fps in that weight range. That would bring your speed up to about 277 fps with a 418 grain arrow. That is about 8 fps faster than what I was getting (string accessory setup differences).

Took it out back and used my own chronograph.. ( the shop used a stabilizer mounted one) and got the following readings.. 274, 274, and 276. so thats a little better... I wouldnt care if it said 240..the smoothness and lack of shock and recoil make up for the little bit of speed I may have given up. And maybe its the long riser, but I find this bow MUCH harder to torque than my Hoyt Havoc.

JoshKeller

Jason,

I also have a 1/2" less of draw, a string loop, and a kisser button added on. I think theres our speed difference . Either way, I shot the projection screen 3d this afternoon and managed a 376 out of 400 so I think its pretty darn accurate
