Midway 55 gr Dogtown

[pacific keeper]

Appear to resemble 55 gr TNT's . 1.1" 20 round group @ 125 yards 25.6 gr's of benchmark . Colt 16" HBAR 1/9. Didn't shoot across the chrony yet . Crappy bench @ dusk ,so I'm pretty satisfied .

From that barrel I'd predict somewhere between 2900 and 3000 fps. They're good bullets. Play with the load somewhat. I've found that sometimes a load that's just enough to cycle the bolt on my AR's is more accurate than "Combat Loads".

I'm looking for varmint fodder . How low can I go ? This is my first mouse gun venture and I am truly astounded at how well these rifles perform .
I'm not getting rid of my 700's and 7's though .....

Realistically, as long as the gun continues cycling, with a 55gr, the low end is probably going to be about 2500FPS in order to maintain good gas port pressure. Realistically, it sounds like you have a pretty good load right there, once you shoot it over the chrony, if the SD is less than 15FPS, I wouldn't change a damn thing.

Changed the rear bag to one that actually supported the stock and shrunk 20 round groups to 7.3 . Now if they shoot in the 20" Armalite ..... Good info on the low loads . Thanks !
