B50 .22 135 Yards Apx
« on: March 20, 2016, 10:17:57 AM »
Following a tune Mr Sterne did on a B51 .22 a while back I swapped the barrel and beech on my .17 B50 to a .22 barrel and breech.  I also did a few minor changes to the valve, and dropped from the 13.3 lbs stock spring to a 12.5lb spring, and modified the spring guide.  The barrel is not straight but it sure shoots straight.  I finished just in time for a range day.  The gun was hot shooting 14.3 CPHPs at 1058 with a linear declining curve.  (I've since reduced the spring to a 10lb for a nice curve)

I sighted the gun in at 50 yards (wheel measured) and played around a bit with various targets on the range.  Then I just happened to see a golf ball on the side of the mountain that is the backstop for the small bore range.  That is about 130-135 yards depending on where exactly.  It took me a little while to dial in, but then I was putting shot after shot on the proverbial dinner plate around the ball.  Finally I decided to try with all my best options stacked in my favor.  A fresh top off.  Five hand selected pellets with no flash, dents or burrs.  I believe the very light breeze even let off for a moment.  First shot at 30 something inches of holdover was dead center and a little low.  Not much.  It threw dirt on the ball.  Second shot was met with the ball flying up the hill side and rolling back down with the faint sound of a thunk a moment later.  I repeated that shot twice more, but then I had to stop.  My golf ball target rolled down behind a fold in the mountain where I could not see it. 

I was also pretty impressed with the amount of energy retain at that range.  The golf ball didn't just roll a couple inches.  I shot up the hill side several feet.  More than a few. 

Three shots in the row on a golf ball size target at 130-135 yards.  That's about the max of my ability with my AR15. LOL. 

I know its an unlikely gun for that kind of shot.  I certainly would not use it for hunting at those ranges, but I was elated beyond belief.  I certainly would not bet money on it, but that cheap Chinese gun just continued to impress me.  Its always been a tack driver at any speed, but at that range I was happy with dinner plate.  When it was given the chance to do better and it did I was thrilled. 

My current tune is bell curved at a lower velocity with the ten pound spring.  Once I get the pellets in I want to shoot, I may need to put a spacer in to add some preload.

Git 'em, Bob.  Heluva shot with 3 on target at that range. 

"I certainly would not use it for hunting at those ranges, but I was elated beyond belief."

What?  Probably giggling lil girl giggles.  You know if a GS, HOSP, YB, G-Hog, P-Dawg---oh, just any legal prey item popped it's head up at that range, you'd be tempted.  C'mon, you can lie to us, just be true to yourself.  ;)

Yup.  Pretty much.  LOL.

P.S.  I've made what I consider bad kills before.  I do not like it.

I just ordered a regulator for my B-50.  The gun is so accurate at modestly high power that I thought it might be a candidate for Bob Sternes 5/5/50 challenge if regulated (or tethered). 

I recently acquired a second B-50 already in .22.  It doesn't hold air so it will require a tear down right away.  I plan to build it the same as my current gun.  I'm not sure which one will get the regulator.  I had considered bottling it, but it has such pretty wood that I would hate to cut it down.  I suppose the first thing it needs is a reseal and to see how accurately it shoots.  The plan is to build the second gun and give it as a Christmas gift to a family member.  One thing I noticed is that it cocks about as easily as my current B-50.  I think it might have had some rework done already.  It also has the same not so straight .22 barrel.  LOL.  As we know already though a perfectly straight barrel is not necessary for an accurate gun. 

Thank you to the guild member who sent the gun to me.  I do very much appreciate it.

I just want to point something out to those who may think otherwise Bob.

Shooting Golf balls at any range is highly dangerous. It can lead to very serious injury of yourself, or the innocent.

I found at short range (under 50 yards) that a golf ball will return the pellet with a lot of force.  I shoot out the rear overhead door of a commercial metal building (my work shop), and I had a couple come back and hit the building.  I didn't find any dents, but they sounded like they hit hard enough to crack a window.  I imagine it would be unpleasant to get hit by one. 

Out at the range I see guys shoot golf ball fairly regularly with .22LR out of rifles, and I know when I shoot one with a .22WMR the bullets do not come back.  Even at ranges of 100 yards the bullet goes through or tears chunks out of the ball.  Its possible that you might get a deflection, but that is a risk with any target.  At Adair range we have a mountain as a back stop, and tall dirt banks to stop side deflections.  At 135 yards I can't imagine my .22 pellet having enough energy to return even a significant fraction of the distance.  I was already shooting about 3 feet of hold over. 

However, it is a valid point.  Golf balls shoot back.  At short distances the ricochet will come back to you. 

What I found makes an equally fun target to shoot that does not return fire are golf practice balls.  Basically they are a wiffle ball the size of a golf ball.  You can buy these for a few dollars for a package of several.  In the past I have seen large bags of these pretty cheap. 



Because of their low mass they move from the pellet hit, and if you hit one with a higher power pellet they puncture.

Hi Bob,
            String those wiffle Golf balls from some monofiliment line on  tree branch and now you really have something to occupy your time.

I actually like to shoot them on the ground because the range changes.  It forces me to adjust POA to adjust POI and learn to the range and elevation more reflexively.

Another alternative is Nerf balls.

I don't even like shooting at swinging targets, resettable outline targets, and anything else made of metal. And this is also the reason I won't go to a cowboy shoot—those metal cutouts just make me cringe!
