CFE-223 Range Raport
August 19, 2012
The Gun: Tikka T3 Lite, 223 Rem, 22", 1-8", Factory Stock.
Scope: Minox ZA5 4-20x50
Perspective:
I'm very happy with my Tikka for the most part, but I hate cleaning copper.
The average range visit of 80 rounds can take over a week of soaking with Hoppes Benchrest to clear out.
I've been very impressed with the performance, efficiency, and accuracy of IMR 8208 XBR powder in my rifle for 100y Grouping. I chose to try CFE223 for the sake of cutting down on copper fouling as advertised.
First Impressions: Toooo Slooooooowwwwwww.
Based on my practices, it's too slow for the 223 cartridge in a bolt gun. Perhaps this opinion will change when I try it in an AR. It's burn rate is supposedly similar but slower then BL-2. I lean towards burn rates between 4198 - 4895 for 223, with 3031 being the sweet spot and 8208 when I want something a touch slower.
It's NO-GO in an M14/M1a/M305.
I think I might find it useful in my Mosin Nagant.
The Rest of the Load:
Bullet: Hornady 75g BTHP 223
Primer: Federal G205M, Small Rifle Match.
Brass: R-P .223, Neck Sized using Lee Collet.
OAL: 2.275"
Chony Data:
PLEASE BE ADVISED: I started with load data for this weight bullet from the Hodgon website, and they proved to be grossly under pressure and velocity for my application.
Results my very.
23.0g - 2369
24.0g - 2415
24.5g - 2489
25.0g - 2641
25.5g - 2635
26.0g - 2799
26.5g - 2879
There are discrepancies with the 24, 24.5, 25.5 data. I got chrony errors during those strings so I don't have the same average as I do with the other charge weights.
Velocities are based on a 5 shot average. I got data on all 5 shots of the 25g charge so I regard it as being accurate over the three flawed datas. These errors are a moot point as I found that anything less then 25g with this load is under powdered.
Any loads tested under 25 showed signs of Under Pressure. The gun did not have the same snap that is does with a proper load and the primers were popped out. The Chrony errors were a listed of less the 2000fps which I'm not sure if it's a read error or an actual dud due to inefficient combustion.
26.5 appears to be MY max load for MY gun with these components.
Primers were subtly flattened as consistent with a max load.
I believe I could go to 27g or beyond, but I think I found a decent combustion sweet spot in the 26g area and will work from there to accurize. The Velocity I'm getting from this range is also more then enough for my twist rate using that bullet. My Most Accurate loads using 8208 and this bullet are ~2670fps.
Please Note: I was unable to fill the case with any of the loads listed . . . and that's not a short bullet.
PLEASE BE ADVISED: My OAL is set to 2.275" NOT 2.5" according to hodgon website.
The partly explains the lack of velocity compared to their load data, but is quite a bit leaner then one would expect from that difference in OAL. 2.275 is a previously established sweet spot for that bullet in my rifle using 3031 and 8208 powder.
After Range Report:
Unfortunately I saw no considerable reduction in Copper Fouling, and in fact had greater powder/carbon fouling due to the inefficient combustion. In my opinion, this powder is too slow for my application.
I believe there might have been some reduction in copper fouling but it was a cooler day compared to previous range sessions which can also yield less fouling. This powder may be a good alternative to those who use slow powders such as Varget for Hot Rodded loads.
Hopefully, I can find a reduction of carbon fouling once I find the sweet spot for this powder in my load.
Groups: Not really. Still working on it. The powder has yet to yield accuracy better then 8208 in my rifle.
