Here is the skinny on my shooting the Ruger Ranch 16" 300 Blackout bolt action rifle for velocity consistency. I bought boxes of each of these following rounds. I shot each type from a random selection of rounds from each box (to imitate a typical shooting session whether hunting or target shooting), recorded the velocity of each round fired and came up with a range of velocity for each manufacturer. This was done using the TSC Hunter suppressor and using the Caldwell Precision Chrono. I weant to find a manufacturer with as consistent velocity per round as possible for less than $30.00 a box. All of the choices would be good for under 150 yard shooting on large targets but only was good enough for near precision shooting out to 300+ yards. My Ruger is capable of 2" groups at 300 yards measured with the Kilo1000 rangefinder and using the bdx system 4.5-14x44 Siera3 scope. The BDX system requires consistent velocities among other accurate "dope" in order to achieve the 1 moa guarantee. However, this shooting trip was to establish the consistency in velocity not group size with the target at 100 yards. I wanted to hit a 3" diameter shoot N see target. Here are the results.
1) AAC 110 grn v-max velocity range was 2979 fps - 2108 fps or 871 fps spread. 50% of the rounds fired were in the 2100's, 30% were in the 2900's, 19% were in the ranges of 2200 - 2400's and 1% was in the 2600's. I considered this self defense ammo within 150 yards.
2) AAC Sabre Blade 110 grn black tip velocity range 2605 - 2233 or 372 fps spread. 35% in the 2200's, 35% in the 2300's, 20% in the 2400's and 10% in the 2600's. Again, this is what I consider self defense out to 150 yards.
3) Ammo Inc 110 grn v-max velocity range 2440 - 2099 or 341 fps spread. 10% 2000's, 45% 2200's, 45% 2400's. Again, self defense out to 150 yards.
4) Hornady Black 110 v-max velocity range 2455 - 2318 or 137 fps spread. 30% in the 2300's and 70% in the 2400's. I believe it would be adequate for most needs out to 200 yards yards.
5) Winchester USA 125 grn OT Range/Target velocity range 2252 - 2178 or 74 fps spread. 40% in the 2100's and 60% in thec 2200's. This is my choice from the stated manufacturers for an attempt at precision shots out to my limit of 300 - 350 yards with the 300 blackout. I can't wait for the Winchester USA READY 125 grn OT ammo to arrive. I'll let you know my results. This was hardly a professional study but good enough for personal use.
