Velocity Testing CCI #200, CCI #34, Ginex Large Rifle Primers in .308 AR 10

[Veteran]

I finally got around to running my tests. I started on this about a year ago, broke my chronograph, got busy, and never did it until now.

I did this with the new Garmin C-1 Zero. I exported excel CSV files and saved them as pdf s to post here.

The #34 were only very slightly faster than the CCI 200's and Ginex. All very close together on velocity.

CCI 200- 2876.9 fps
Ginex - 2883.5 fps
CCI #34- 2885.7 fps slightly faster but all close

The Standard Deviations for all were very good, CCI 200's the best, and the #34 the highest.

CCI 200 - 10.1 STDev
Ginex- 11.6 STDev
CCI #34 - 15.3 STDev

The Extreme spreads were in the same order as the STDev. CCI 200 best, CCI#34 worst.

So, Ginex was pretty much in the middle in all of these shot strings of the CCI 200 and CCI 34's.

Each (8 shot) shot string was fired in around a minute. So, relatively fast semi auto fire on each 8 shots because I was most interested
in velocities. But lo and behold, look at the target I shot up at 100 yards. That was really good 3 shot string accuracy for 24 shots
shooting that quickly. This rifle has a day/night digex C50 night vision scope, not even a Swarovski or Leopold.

A friend here on LRH built it for me last year. All the load info is posted on the following charts.

Love this data, great work.

I wish you had 1000 data points for each primer, but that's a statistical fantasy world.

Good stuff.

AVERAGE 2883.5
STD DEV 11.6
SPREAD 37.1

No reservations about Ginex primers.

I ran some CCI 34 primer loads for 6.5-06 & Staball HD thru my chrony & came up with:

The .308 CCI 34 data with H4895 showed:

AVERAGE 2885.7
STD DEV 15.3
SPREAD 54.1

Two different rounds (6.5-06 vs. .308W), different powder weights, different powder types (H4895 extruded vs. Staball HD ball) but some similarities.
Ginex primers look good.

Yes Stdev same in your data and mine for CCI 34.

Ginex right in the middle of CCI 200 and #34.

I have no problem loading Ginex large rifle all day for hunting, for range, hogs, coyotes, etc.

Matches, data says go w #200.

And he DOES! Well DONE @Hugnot!

I will add delta info (dif. measured to average) to my spreadsheet display.

Wow, your getting a lot of velocity from those hammers.

Lot of velocity for .308 w 22 inch bbl. Very nice.

You answered the question Ive had about how good the Ginex primers are.

Tac they came to life. Case full of varget barely hit 3000. 47g varget was in 2900s.

Yes, hammers need a little hotter burn rate powder than normal bullets to realize their potential.

I didnt look, but assume TAC
is higher burn rate than Varget.

Yes it is.

TAC + Hammers in .308 has been exceptional. Our friend BFD loves this combo.
