Beeman R9 Fiasco - Chapter Two

Thanks to everyone who provided feedback on the first part of the thread. Did a lot of follow up work with the R9 today. Cleaned the barrel and tightened a couple of stock screws. Then went to town in my basement 10m range with the R9, open sights only. Shot 10 pellet groups at a 10m target using all my different pellets. Started off a bit depressing but learned a lot over the day and was doing better at the end of it.

First run with all my different pellets, not too thrilled with this...

Worked and worked on just letting the gun do what it wanted to do when I shot it. Still I thought it would be better than this. The group sies are all measured CTC. The red number is the overall group size, the blue number is the width of the group. I noticed consistent vertical stringing of the shots. I am interpreting the narrowest groupings as the more accurate pellets, just a hypothesis.

Next I got out my Benjamin Trail NP2 0.22 cal and did the same test with all the different .22 pellets I have. I shot the Benji with a cheap Centerpoint scope. Please note that I adjusted the scope between strings to get the groups closer to center, was only looking for group sizes at this point.

The Benji shot better and no vertical stringing. I think the issue with the R9 was something to do with how I was using the open sights. Then I remembered that a bunch of replacement inserts came with the R9 so onto the next experiment..

I shot 10 shot groups with sights #1, 2, 3, and 6. Inserts 4 & 5 were unuseable with my target selection.
Here's the results, sorry if my notes are a bit confusing... All pellets for this test were Crosman Domed 7.0 gr

I found sight #6 using a 6pm hold was the most precise.

Good news, after a couple of hundred rounds my flinching was reduced quite a bit. Also probably well on the way to breaking it in properly. My conclusion is I would love to keep working with and shooting the open sights but really would like some type of rear ghost ring. Would a Tech-Sights type set up work or would the break barrel hinge make it pointless to try? Curious about the vertical stringing. I see the potential for accuracy with this gun.

"oh yeah, uhh I was just shooting my springer all day, yeah..."

You can mount a Williams peep sight in the scope grooves-it will give you a longer sight radius. Be aware there are different heights available. Might be best to buy from Midway and chat with a sales rep to make sure you get the right height. They're not cheap, but are well worth the $$.

I have found that the HW95 likes the 10 gr pellets the most, right around 820ish fps. I suggest trying a 10 gr JSB or H&N pellet and see if your accuracy improves.
Thanks, will try it. Heaviest I have are the 8.64gr H&N FTT then a quantum jump to the 13.43gr JSB Monsters. The 8.64gr shoot around 870fps, the big Monsters 700-710fps.

I'll look into it, really like rear peeps with a front post from my service rifle shooting. Will have to take some careful measurements.
 
3 things you may watch.. the insert set thing screw can loosen.. my ne the big thing was the front globe walking up its dovetail you see what ot took to stop that .. it stays put on the end of the muzzle now .. then the rear can shift ..

The globe walking was the biggest issue . That weak flathead screw just cant hold it .. but a bolt and nail polish as glue and movment indicator ( if it cracks its moving) pit a stop to that and poi shifts. 😉

First picture you see the globe walked up the dovetail and climbs the sloped part, not good ..

Seems like Tech sights have been mentioned here. Maybe do a forum search and see what pops up.
I love Tech Sights and have them on my 10/22 and mini-14. My only concern with putting them on an air gun is the vertical adjustment range is not that great. The bases are specifically sized to work with actual specific firearms. Still will look around.

I have not noticed any movement of the front sight in the dovetail. I will try the nail polish trick though and watch it. In any case my shot inconsistancy is vertical. My R9 seems to be shooting dead on left/right. Thanks
 
Dont forget to match the rear sight notch to the post used... If you (and should) use the lolly use the "U" notch and cradle the ball in the cup so to say..
Thanks for the idea but when it comes to open sights I love rear peeps. I've had them as standard issue on my M1, M14, mini-14 and AR rifles over the years. Combined with a simple front rectangular post they are the best sights for me. With the stock square notch on the R9, the lollypop front post is the best of the ones that shipped with the airgun.

Newer gun maybe the seal settling in .. ill bet just some growing pains.. it should smooth out as your shot count goes up.. ( opinion).

In my opinion the globe front sight needs to be set right on the end of the barrel not back on the slopped part of its dovetail. / As forward as possible..

Then ya, ok on the rest.. oys what you thinks best for you i guess..

Just ordered a tin each of 10.34gr JSB Heavies and 9.57 H&N Baracuda FT's. Will see how they do. Regards

A random Beeman R1 manual I found online mentioned a 1,000 shot count for full break-in of the spring/piston/firing mechanism. Imagine similar for the R9. I'm at about 300 now.

Well.. the globe if back on the sloped part of its dovetail will walk up and can cause that vert stringing.. goes to why mine is bolted on as i showed and mounted away from the sloped cut end of the dovetail and at the muzzle end. Just a fraction of a fraction of a mm riding up the slope gives that vert stringing. I did not " fix" mine just for the fun of it..

The lolly and U notch is most accurate combo with the proper 6 oclock hold. Not the 6 oclock hold for assault guns or pistols.. it's target compition not military spray and pray...

Heres another trick ive done to work on my hold . I call ot the cant cante device 😉 ( temporary glued on in place)
