I’ve been testing a large number of different arrow designs for the past month. I still have a long way to go. Unfortunately, Post Image will not let me log on.
I’m testing for accuracy and trajectory . I’m working on very flat trajectories.
The xbow is a M380 with an Optimizer/T36 Weaver with lots of other acuratizing features such as a 1.5# TT, wind flags, benchrest set up.
Two arrows have stood out so far.
20” Spynal Tapps, the new 2 piece 60g insert from Jerry, 4 degree offset SK300s, flat plastic nock, 125g field point.
20” XX75 (0.001”), 50g insert, 150g field point, Easton AL insert, 4 degree offset SK300.
Today in very windy (>10mpg, gusty, , variable). 80 yards. 2 - 2 1/2” groups.
In no wind, from previous testing, both will do 1” 3-shot groups.
If you’ll notice, both arrows have fairly low point weights, great trajectories and excellent accuracy.
The 2219 is as accurate as the 20” ST but weighs 520g overall. The ST is just over 400g.
The traditional 18 ST, 110 insert/100g Point, , helical Blazers, flat plastic nocks were as accurate but had a much poorer trajectory.
That’s all for now. I’ll work on pictures. I’m at a loss concerning Post Image.

thanks steve i will be watching
Re: Arrow Testing
I'm assuming that's a 2219 shaft? Where did you get the 50 grain inserts from? The only source I've ever heard of (and it was recent) was Ethics Archery, and they list a 60 grain insert on their website but no 50 grain.SEW wrote: ↑Fri Mar 30, 2018 11:27 pmI’ve been testing a large number of different arrow designs for the past month.

Re: Arrow Testing
If you want to lighten the back of the 2219 XX75 arrow a little, you can lose 6 or 7 grains by using the aluminum "PDP Cross Bow Bolt End" instead of an Easton insert as a nock. Lighter yet, there are plastic flat nocks available for a 2219. If you wanted to keep a threaded insert as a nock, but wanted lighter than aluminum, there are composite inserts available too: https://www.amazon.com/TenPoint-Crossbows-Aluminum-Crossbow-HEA-271-12/dp/B005FMJZDG/ref=sr_1_1?ie=UTF8&qid=1522514344&sr=8-1&keywords=2219+tenpoint+inserts
Good luck and thanks for the info on your testing!

Re: Arrow Testing
Thank you for sharing your results please pass along further results as they come in I have gone back to 2219 aluminum shafts and have been impressed with the hard hitting penetration I and accuracy am getting and look forward to your future results.
