Spring piston observations

A friend of mine and I went to the range yesterday with spring piston rilfes to practice and experiment.

The spring piston rifles present were my TX-200, an FWB 300 an Paul Watts tuned R-9 and a Watts tuned HW-77. So, we had two under lever rifles, the TX and the HW-77, one side lever, the FWB 300 and a break barrel the R-9.

Practice included, attempts to improve shooters skill and some additional pellet testing. And trying to read the wind. We had two quality flags set up. The wind was fairly light but with a front comming in it was very shifty. Temp about 65 degrees.

The rifles we were using have been tested for accuracy and performance, so this was not as much a rifle test as it was an attempt to perfect skills on the part of the shooters. We both shoot rimfire bench rest off one piece rests with rifles specifically made for that purpose.

One problem that remains kinda up in the air (as I see it) is the type of rest set up to use for matches with spring piston rifles. As ya'll know you have 20 minutes to shoot 25 shots for score and any sighters you think you can get in in the allotted time. Before I go any further I want to make it clear that This is NOT an attempt to change the rules. I believe that we need the year or so to get things going and rule changes just confuse and take up time that could be well spent on promotion of the sport. We clear on that?

I have been shooting TX-200 pellet rifles for a number of years. I made a front rest out of Sunbrella, a tightly woven acrilic heavy fabric often seen on boats as biminis or covers. Water resistant and sun resistant. And I could sew it on a machine that I have. So, I built this owl ear bag a little higher than the store bought ones, filled it with sand and put a piece of leather on the center of the bottom of the part that holds the rifle. It is a little wide for the fore arm but sits solid on the bench and is maliable enough to settle the rifle in to a point of aim. Used some pillow type bags for the rear.

As a general rule on spring piston rifles you find the sweet spot on the fore arm and shoot as much free recoil as you can. Consistancy is the key here. Because you cannot eliminate the effects of the firing cycle, unless you have one of the 10 m rifles that have some method of recoil reduction such as the FWB-300, the RWS 75 and the Anschultz 380.

OK, the challenge is to fet the rifle out of the rest, cockie and loaded and back in the rest and on target with as much speed as you can so that you have time to work the condition and maybe even shoot a sighter once in a while.

We tried an adjustable top front rest, with custom top and of very fine quality, One of them Orange Hoppe's rest with a nice bag on top, and an adjustable rear rest, and my bag set up as described above. My friend liked the Hoppe rest with a good bag and a piece of sheep skin with the hair up lying on top of the bag, and the rear adjustable rest. Pretty good and consistant set up. Don't know how much he actually used the rear adjustable rest for the purpose of adjustment, but it is there if you need or want it.

The front rest with windage top and a similar bag set up and using my rimfire bunny eared rear bag made a tall rest. Need the adjsutable drummers throne, but left it at home. You seldom had time to use the front windage adjustment and or the speed screw in the rear leg of the rest. Now, for relaxed shooting, this set up is nice. Works very well, and I was able to shoot Xs more often than just 10s with this set up, when I took my time.

OK, you may be asking what is the point of all this rambeling. We'll, the point is that springerss are fun to shoot off a rest, been doing it for years informally. They can be very accurate. They are a challenge to shoot in our competition but a challenge that is not insurmountable. I encourage all spring piston rifle owners to give this a try. It's sooo fine a feeling when you shoot a doughnut. Don't come often enough to get used to it, so it is always a thrill.

What are ya'll finding as far as rests that work well on springers.

I like shooting my TX200 off of a Caldwell Tack driver bag. Excellent results,
 
More of the story

I bought a Caldwell Front rest with windage adjustment. I think it is the smaller of the two that Caldwell offers. This unit was assembeled at the gun shop so I had the chance to look real close at how it was made. Everything seemed to work reasonably well, so I bought it and a Protector 2"bag. Brougt the rest home and took it unappart and cleaned the threads on the base plate screw hole and the screw with alchol and used blue lock tite to secure it. Did a little filing aand sanding to the surfaces that the plastic spacers ride on on the lower top they were rough enough to cause premature wear with use. Took out the spring that is part of the windage movenent mechanism and cleaned the tube and spring and lubed the spring with air gun spring lube.

I finished the caldwell rest just about an hour befoore we went to the range to shoot. In addition I swithced stocks on my TX-200 MKIII. Took the beater stock and removed the but pad and drilled a hole for a 1" diameter piece of thin walled aluminum tubing that had been filled with poured lead. Left but pad off as it made it easier to get around the but of the rifle without thouching it.

For a rear bag I am using a bunny eared bag with a single layer bottom tacked to a 1/4" piece of plywood, then the wholw thing is mounted to a one inch piece of oak. I do not like the way the oak moves on the concrete benches. Seems that you move it too much or not enough and it will not stay in place needing adjustment every shot.

I have removed the safety on this TX-200. I spent a few days working with the trigger and have it light enough that you can shoot as close to free recoil as you can get and still have a reliable and safe trigger. Plugged the hole in the reciever with a red plastic part that just fit, to keep dirt out.

The wind on last Thursday was really swirling at the 25 yard range. The range has a concrete wall on one side and tall berm on two sides. Carches the north wind and makes it go in circles.

As to the performance of the rest, it is fine. Seldom use the windage adjustment, just don't have time. For elevation I was using the rear bag, but the rear foot of the rest adjustable screw unit did OK as well.

I intend to experiment with the rest and different balance points and rifle weights. Need to find some kind of feets for the rear bag as the falt walnut is difficult to position and won't hold position. I will also use this rest for a stock rifle bench rest competition that the club is starting this year. You have to shoot off sand in this class and this rest should work well enough.

We continue experiment with and shoot the springers at the Standard targets. Got lots to learn and having a good time doing so.

Any comments or suggestions are appreciated.
