Beeman P17 - accuracy at 50 yards

I managed to get a perfect day for testing the P17 accuracy at longer distances. A mild rain just ended so I set up my bench in the dead calm conditions. The long grass was completely still and not a leaf was shimmering. I made the best of it and tested the Beeman P17 pistol from 10 yards to 50 yards with 10-shot groups. The groups looked consistent and surprisingly tight.

My P17 wears a Millet SP-1 red dot but I have been using this 3 MOA optical sight on air pistols for 14 years so it's quite comfortable. It might not be as precise as a high mag rifle scope but I enjoy the dot sight and it works well if you use an appropriate aiming spot.

Beeman P17 - purchased new in May 2010
8.44gr JSB Exact 4.52mm - Lot #6070016
Tested velocity - 394, 394, 391, 395, 394 - ave 394 fps

Accuracy with 10-shot groups (ctc)
10 yards - .49"
20 yards - .89"
30 yards - 1.31"
40 yards - 3.09"(10 shots) - 1.95"(9) --- 2.69"(10) - 2.08"(9)
40 yard - 2.86"(10 shots) - 1.52"(9) --- 2.92"(10) - 2.54"(9)
50 yards - 3.02" --- 3.89"(10 shots) - 3.04"(9)

Notes:
> Several of the 40 yard and one of the 50 yard groups had one flyer. I included the measurements for all 10 shots and also for the best 9 shots in each group.
> The 40 yard average without the flyers is a hair over 2" ctc.
> The 50 yard average without the one flyer is a hair over 3" ctc

Tested Trajectory
10 yards - 3/4" high
20 yards - 1/4" high
30 yards - 3" low
40 yards - 10" low
50 yards - 21.5" low

I got about .700 at 12 yrds with a red dot, so these numbers make perfect sense. with a 12 x scope and a buttstock , ill bet you could do even better ! very cool

Target groups

I just joined imgur so I'll try to post a couple of pics. For 30, 40 & 50 yards I pinned a target above a blank paper so the shots would drop onto the page. Here is a group from 30 and one from 50 yards.

What a tour-de-force in marksmanship and ballistics!

I hope you won't mind, but I couldn't resist plugging your excellent data into an old post of mine.

Might have been Warren Page ("the Accurate Rifle"...45 years old, but still an interresting read).

Something like "every target is a weather report".

Meaning that mother nature (and with wind in particular) has a lot more to do with the target than we'd like to admit.

Not taking away from your ability to handle that little short pistol, but that had to have been an exceptionally calm day. It's a LONG time between the "pop" of the pistol being shot and the sound of the target being hit getting back to you....and a whole "carp load" of bad ju-ju between here and there that you've no control over.
