Hi everyone,
I am new to the forum so please bare with me. Over the past few months I have been visiting the forum with more regularity, trying to expand my rimfire knowledge, and now I finally have a question to post.
Anyway, I don't shoot benchrest, I am a smallbore position and prone shooter, however, I have always paid close attention to the what's happening with benchrest to help improve my equipment.
About 2 years ago, I had my rifle rebarreled and at the time I got a "Harrel" tuner with bloop tube. I experimented with the tuner and was amazed at the difference it really made. I was extremely pleased with the way I was able to tune the ammo but the bloop tube was a pain in butt for me when I shot iron sights. Despite what people might say the threaded bloop tube was not a good idea. I could never get the tube to bottom out at the same spot every time. Now I don't have a problem having to adjust my sights, but I do have a problem when my sights are completely off the paper, and occasionally this would happen. In the end I got fed up with the tuner, because of the the threaded bloop tube, and went back to the old style clamping tube which was much more reliable on being sighted in.
I would like to be able to use a tuner with my rifle, but I want one that is like my current clamping bloop tube and haven't been able to find one. The closest thing I have found is the beesting tuner, which is perfect except for the price of plus $360.
Then yesterday, I was over at my friend's house, working with him on some rifle stuff, in his machine shop, when it hit me that it really wouldn't be that hard to make a tuner like I want. So my understanding of a tuner is that it is essentially just a moveable weight. Therefore, I was thinking of cutting some threads on the outside of my current bloop tube and making a weight to go on it. I already have a 3oz weight on it I made but its just held on by a set screw and its position can't be adjusted in fine increments.
I have read about determining how much weight you need on a tuner but I haven't been able to find anything on how much adjustment range you need. So my question is how much total distance do I need to be able to move my weight over for it to make any difference? On the tuner that I have the scale is only 1/2 an inch so is that about all the distance I need? I have already experimented with adding weight to my tube and taking it off to see how much weight changes my point of impact so I think I have that component figured out. Also where on my tube would be a good place to have this tuner weight? I shoot an 18 & 3/4 inch barrel with a 15 inch bloop tube. I want to put the weight back next to the muzzle of the rifle. From measuring the current tuner I have it is moving approximately 0.02 inches per revolution of the weight. Does anyone know what pitch thread I would need to duplicate this?
Thanks
