Today I took my complete upper from MidwayUSA to a friends house to shoot and get some data. It is a 18" 1:8 barrel in .22 Nosler. Here is my report on it.
I fired approximately 40 rounds and had ZERO issues it was 100% reliable.
1-28-16 50*F 15mph wind
All rounds fired is new unfired brass with Tula Small Rifle Primers
.22 Nosler 55gr Hornady SP 29gr H-335 COAL 2.225 is .5gr over minimum. Accuracy was 2" or slightly more at 100 yards. It's not anything to be proud of.
Velocity 5 shot average : 2991
Nosler list 28.5gr H335 @ 3169 in a 24" barrel. I estimate 29gr H335 @ 3234.
That will give a 40.5fps loss per inch.
To give perspective a friend has a .22-250 AR-15 that's right NOT a AR-10!!! His 20" barrel with a 55gr clocked 5 shot average 3246. The 22 Nosler will not match that unless it has a much longer barrel.
There is no published data with this caliber and H-4895 powder. USE WITH CAUTION!!.
22 Nosler 68gr Hornady BTHP COAL 2.260 I loaded 1 round of each charge starting at 25.3-29.2 in .3-.4 increments.
With Bruce Finnegan help and help from Sierra Ballistician we can up with 25.3-29.2 min/max.
25.3 2629 25.6 2629 26.0 2688 26.3 2743 26.6 2766 27.0 2801 27.3 2849 27.6 2917 27.9 2923 28.2 2982 showed slight head swipe and a slightly flat primer.
28.5 3009 is MAX in my rifle. It had considerable head swipe and a flat primer.
I did not shoot 28.8 or 29.2 I will pull them.
Using 1 round per charge showed accuracy potential as all the rounds were in a vertical line with little horizontal stringing. Looking at my target I predict an accuracy node in the 27.5- 28.0 grain range. That charge range had the least vertical stringing and the least horizontal stringing.
