It was too cold today to be outside. So I did this in my bedroom using a large BassPro catalog, a Gander Mountain catalog, Natchez Shooting supplies, and MidwestUSA catalog. Penetration was incredible, almost made it through all the magazines. Looked to be about 5″ thick and a 50-60 page buffer was left at the very back after the shooting stopped.
If the POI over 40 shots is not more than a few tenths of an inch at 33 meters, I don’t plan to use a regulator. Why fix it if it ain’t broke? If I’m hitting 835 fps after 40 shots, and reaching 28.5 fps, with 18.1 JSB’s, what’s not to like?
Unless my new Combro is totally out of it’s mind, I must admit I am surprised at these numbers. I expected much less in a 15.5″ barrel carbine!
I’ll do some accuracy after it comes back from the machinist with the new 1″ extra quiet, shroud.

Uncle H 😯 😯 T

Hoot, that puppy is showing some good breeding! 40 shots is a darn good hunting trip. And those AA pump up fast. Shootin through ’bout 5 inches of catalogs, 50-60 pages left?! 😯
It’s too cold to be blowing holes in yer wall.
A bunch of us are eager to see the groups, especially w/ the 18.1 gr. Haven’t tried those yet, only the 15.9gr.
How is the new chrony working? The shot-resistant design is tempting, I need to get some sort of chrony.
Beech, European Beech, is a fine, hard and stable wood. (American beech, for some reason, sucks; it checks all over the place. The only use I’ve heard for Am. Beech is popsicle sticks.) I got the longer version s510 in “Poplar” and no one could tell me exactly what the hell that means: Tulip Poplar (Tulip Tree), American Poplar, European Poplar? It’s light, but I should’ve gone for a harder wood; got few micro-dings in it already.
Let’s hope it warms up a bit by the time you get your gun back. Otherwise it’ll drive you nuts, kinda like a cat behind a glass door, staring at a bird…cackkkk,cack.cc.cacacac…
You know you’ll get out and shoot some anyway, even if everything is screwy ‘cuz the gun, scope and you are going from 60+ degrees to below freezing. “Got some great groups today..was so cold my nose was running and froze the stock to the bench real good.”
