I got my 19" JC-Optimus riser in from John this morning.

I had planned to "not" swap the limbs over to it yet.
But, I couldn't stand it. Had to see what she was gonna be.

Set at a 6 & 7/8ths inch brace height, the profile is perfect.
Limb bolts max in, she's 67# @ my 29.5" draw.

I shoot even tiller, so once I tiller the 1/8" positive out of it, it'll probably be right at 65 - 66#

Since I'll probably only be hunting with it, I decided to just use a NAP Center Flipper rest.
At least for now, because now starts the tuning all over again, and I need to be doing some pig hunting.

One things for sure - She's gonna be a shooter. :DD

63.5" OAL

Two things to keep in mind while you read this post, and look at the pictures.

(1) These arrow are very weak for this bow, and I have to tune them well outside center to get them to shoot.

When I get my Backwoods Composites limbs, I will be altering (which will include cutting them down) the arrows to shoot with them on my 21" riser, and will retune this 19" riser with these Borders limbs to shoot them after that.

The tune (I suspect) is going to be very close between the two bows.

(2) By the time I got to the chronographing phase of this, I was one wore out feller, and the heat (102 degrees) was taking it's toll, so my consistency started to falter a bit. All toll, I bet I shoot 150, or more shots.

The bow (19" JC-Optimus riser with Border Hex 6.5 Longs) is 63.5" OAL, and 67# at my 29.5" draw.

This is the final tune, and she's hunt ready:

1 bare shaft, and 1 fletched target arrow from 25 yards.
1 bare shaft, 1 fletched target arrow, and 1 broadhead from 20 yards
My tab is hanging on the arrow with the broadhead (175 gr VPA 3-blade).

These arrows weight 642.2 gr, which makes them a tiny bit over 9.5 gpp.

My target butt is an 8" thick layered insulation foam target butt, that is also backed with 1/2" rubber horse stall matt front & back

From 20 yards, the arrows were going all the way through, and sticking through the 1" MBS board behind it.

The only bow I have capable on that till now, are my Martin Firecats that are upper 90's to 105" at my draw, and shooting 605gr arrows.

I was shocked to put it mildly, and knew I wasn't going to be happy until I fixed my chronograph (broken battery connector), and see some speeds.

Here is the high/low of 5 shots with the normal 9.5 gpp 642.2 gr arrow:

Here is the high/low of 5 shots with a 10 gpp 669.8 gr arrow:

Here is the high/low of 5 shots with a 12 gpp 805 gr arrow:

And, just for some added shock factor, here's one & only one shot with a 6 gpp 404 gr arrow:

The Chrony may not be accurate, but I bet it's not of by much.

I'll be staying with arrows between 9 & 10 gpp (as close to 9.5 as I can get).
