RE: Bowtech Patriot DC: Early Impressions...
Just to play devils advocate here…let me throw out some numbers…<img src=icon_smile_big.gif border=0 align=middle>
Basically I have found that I can drop 8-10 lbs of draw weight on the Bowtech DC bows and still produce similar or better KE than I can with most other competitors products. And most of time I can match or beat arrow speeds with similar weight arrows despite the draw weight loss
For example:
Let me give you some relative info based on Aussie's report (and bear with me here, please). He stated his DC PAT shot 288 FPS with a 345 grain arrow. 28" draw 61 Lbs..loop and kisser on the string & the BT silencers. (no peep).
Last year my 28.5" cam (29" actual AMO draw length)[b] SEVENTY[b] pound Mathews Legacy shot a 355 grain arrow at 287 FPS (loop and peep..no silencers).
So if exact draw lengths and arrow weights were taken into account they would be damn close speedwise as is. Brace heights are similar for the two bows as well with the DC PAT being slightly higher
.Now..think about this...Drop that Legacy down to a 60 Lb peak model. You'd drop about 18-20 FPS with the same arrow weight...So now that 60 LB legacy would probably shoot the same 355 grain arrow in the high 260's
Now drop the draw length down 1/2 to 3/4" to match the 28” DC PAT (assuming it’s a bit long)...another 6 or 7 fps lost from the Legacy....so let's say 262...then a 2-3 FPS gain for dropping from a 355 grain arrow to a 345 grain arrow to exactly match the DC PAT's arrow.
So we are at about 265 FPS for the Legacy. So you've got about a 23 FPS or so difference between the two bows, yet everything else has been equalized
Now let's assume we wish to shoot at 5 grains per LB. Drop 45 grains off for both bows. On the DC PAT this will add roughly 20 FPS for a 5 grain speed of 308 FPS. On the Legacy we will give it the benefit of the doubt (the SL3 cam on the Legacy is more efficient than previous SL cams) and add 20 FPS as well, for a total of 285 FPS. Same brace, same arrow weight, same draw weight, same draw length.
Now speed isn’t everything but if you are taking how hard the bow is to draw into account, and how much oomph is there, it’s certainly not a wash. If noise is a big factor, now bump the arrow weight on the DC PAT to match the same exact speed the Legacy is getting. While it still may not be as quiet as the Legacy, the difference will be not that great.
I’m not picking on Mathews here, I like the bows. I’m just using the Legacy as an example because my speed test numbers for it mirrored very close to Aussie’s and the fact that the bows have similar brace heights and draw lengths.
Even a slightly faster Mathews model like the Conquest or Feather-Max , still would not match up with the DC PAT (and the brace heights are lower on those 2 models). Neither would my Y2K Hoyt Defiant (6 & 7/8” brace, 70 Lbs 29” draw 352 grains at 289 FPS), 2002 CyberTec V-cam (6.75” brace 70 Lbs, 29” draw 352 grains @ 288 FPS),or several other models from various manufacturers I’ve owned in the past couple of years.
I can state from my own personal experience that drawing a 60 Lb harder cam bow all day, does not wear on you as much as drawing as a relatively smoother drawing 70 pounder. It will be easier over time on the range and also will allow you to get “over the hump” easier when drawing on game with the harder cam with less draw weight.
Just some food for thought.
