Just wanted to share the load I found, since the gun and components are a bit different than the normal stuff posted ... maybe somebody out there will be helped by it :)

Gun - EAA Witness Match .45ACP, 4 3/4" barrel
Bullet - Montana Gold 230gr JHP
Powder - 8.5gr AA#5 (actually about 8.55gr)
COL - 1.260 - 1.262"
Primer - Fed 150
Lee Factory crimp

I don't have a chrono (one coming shortly), but this should be approx 900-910fps from the best I can gather. My process, I made some dummy rounds first anywhere from 1.200 up to almost 1.270. I went with 1.260 because it was the longest that fed perfectly. I started around 7.5gr and worked up with 30 rounds at 7.5, 7.7, 7.9, 8.1, and 8.2. That was my first trip to the range, and they all grouped well at 7 and 15 yards, but it was clear that the 8.1 and 8.2 loads were grouping better at 25 and 50 yards. Next batch I made 8.2, 8.4, and 8.6gr loads. Of these (which I shot just yesterday), the 8.4 and 8.6 grouped best, both were doing under 3" at 50 yards benchrested of course. But the 8.6 had a noticably bigger flash and felt like a full power load, but no primer flatening or any signs of danger. So today I decided to try the 8.5gr load and it performed perfectly, best 5 shot 50 yard group was 1.4", average about 2.2" ... and the load felt very nice in-hand.

Who knows how the Montana JHP's expand, but they sure are accurate! Comparing them visually to some Hornady XTP's and Gold Dots it's easy to see a 'fit-and-finish' difference. The Montana's are just cleaner, every one looks like it's been hand polished and de-burred. I'm sure this has something to do with their accuracy.

BTW - I cleaned after each group of 30 rounds.

I also have a XD45 4" barrel that I'll try this load in as well and report back, but I doubt I'll do the full workup for it.

8.5 Grs AA #5 and a Zero 230 Gr JHP @ 1.245 O.A.L. gave me an Avg 859 FPS from a 4" CDP II in 85 degree weather with very good accuracy.

9.0 Grs AA #5 and a Hornady & Ranier 200 Gr SWC's @ 1.260 O.A.L. gave me an Avg 893 & 897 FPS from a 4" CDP in 95 degree weather with very good accuracy.

9.4 Grs AA # 5 and a Speer 200 Gr Gold Dot @ 1.215 gave me an Avg 876 FPS from a 3" CDP II and 910 & 919 from a 4" CDP I & CDP II in 90 + gedree weather with very good accuracy. (The load I tested Gold Dots with for funtion in my 3" CDP carry gun)


Good Stuff.

These loads were safe in my gun using my load procedures. Check all data and use at your own risk.

My P220 SD load is 8.8 gr AA#5 under a 230 Gold Dot. Never have chronoed it, but have checked 8.5 grains of AA#5, CCI 300, a "hardcast" 230 RN and got:

891 fps avg in my 1911A1

867 fps avg in my SIG P220

Temp was 55 degrees and was shot in 1995 with propellant made in that time period, by the then current contract maker. Posted just as a rough velocity guide, and as you know your results will vary. Good luck, and keep enjoying that AA#5... Good stuff!

I have wondered if anyone has used a EAA Witness in Bullseye shooting. Yours and others seem to have the accuracy to do so.
