Is a High-Power Sub-MOA Bigbore Even Possible? (Video)

Here Is a group with one of my PCPs I shot one of my 73 grain slugs @940 FPS

I was using a 26 inch L/W unchoked barrel . sitting with Atlas bipod , the weather was 31 degrees F , wind steady at 4 MPH , I shot a 5 shot group and it measured just under 2 inches and it was 230 yards

Wow! A slayer? Something extremely high powered?

Too Much Trouble: have the camera(s), meticulously plan your shots, do all the equipment setup to record your activity, then have to edit which can be a real PIA. And THEN there is the downloading, jeeze!

I just want to shoot and have no desire to show how bad I usually normally am (I'm a work in progress)... what you see in peoples may be the highlights with the poor cut out... gets back to that editing thing again, whats real when you watch the video?

Not sayn their all that way but again, I just want to shoot airguns. If I wanted to shoot video I would be doing porno, haha.

I have a DC1000 Scope cam that I use for night hunting and with a filter for daylight but again I don't need to record (nice system https://www.digitalcrosshairs.net/ ) I had what you might call a 'stroke' in my right eye optic nerve and have found that I shoot better with the screen and the left eye, still right handed. We adapt and overcome!

You should mention what camera you are using in your videos.

FYI - I have camera(s) in my track car but that's different, I use it to diagnose my driving and get better, haha

How about a 5 shot @ 170 yards MOA? The whole 10 shot group is something Ted came up with. IMO this doesn't test the gun but the shooter's concentration. 3 or even 5 shots will do. If 3 shots good enough for military and law enforcement it's good enough for me.

A nitpick I know, but an important one: Ted Bier didn't invent the ten shot group, it has been used by shooters as a standard for a long long time. I suspect Ted uses the ten shot group because he is a scientist, and understands the statistics behind it. Long story short, when testing the capability of a gun, 10 shot groups are better..... it is a math thing. Even if you're just looking for a quick and dirty zero, 3 shots doesn't really cut it.

Rather than diving into the technical side, I'd suggest a simple experiment. Put up a target with ten bulls on it. Shoot a three shot group holding for dead center on each. Now look at your target. Each of the three will, aside from a few fliers, tend to cluster so each will look like a reasonable group. Target to target though, these clusters will be all over the place. If you overlayed them, they wouldn't all line up in the same spot but instead would generate a much larger group than you'd have thought given the size of each group of three. That matters for two reasons. First, the goal of paper punching like this, aside from honing your skills, is to generate an understanding of the true angular MOA capability of your rifle. Shots will land in a standard distribution, and that is important and leads to the second reason: you want your crosshairs to be set for the center of that standard distribution, that is to say the area with the highest density of probable impacts. 

I hope that makes sense.

I agree about Ted's 10 shot standard for small bore.

But,...bigbore...5 shot may be should be the standard. They are inherently less accurate, and use a lot of air. Maybe 5-shot sub-MOA group would be the new bigbore benchmark.

10 shot sub moa with a big bore might be tricky un tetherd being the drop after two to five shots can get so dramatic that depending on caliber and airgun you could basically have 9 different holdovers at 100 yards but if you did it tetherd you would have a much better chance, I only shoot my big bores tetherd that way my shots are more consistent and I don’t have to refill the airgun all the time, more shooting less filling is my motto.

Most of your big bore air rifles are use for hunting purposes in a hunting scenario you’re not going to shoot or kill ten of any type of animal Deer ,hog you name it . So for me with the big bore a ten shot group is useless besides you need to have a lot of air with a big bore . I mean a lot ,Tethered With a large amount of air on hand. I can shoot a 3 to 5 shots sub moa group at 100 yards all day but For consistency I would need to feel the rifle every time right back to the same pressure. I am mostly a hunter so wouldn’t do me any good Because I know I’m not going to shoot 10 hogs in one night with the air rifle maybe with my AR but not with the air rifle.
