Busdriver,
Do any prone shooting? Just wondering. But as you can see, using the MR65 target would more sense in many ways. I am just thinking out loud here and having different frames, well at our club, we have plenty of frames and carboard, so that is not a problem, also practice targets would be easier to distiguish. And to tell ya the truth, your not going to get the prone shooters to switch from the current format. I don't know if you shoot prone or ever have. If you haven't you should try it first. I would say that you hard pressed to consistantly hold a strong score. If you think about it, not that many prone shooters find it all that easy to clean the MOA target that is being used today, which is a tighter target than the V target of yore. If the MOA prone target was so easy, cleans with 20X's would be shot rather often.
Now if you want to tighten up a prone target, tighten up a smallbore prone target. Or just better yet, shoot a metric target at further distance. Want a tight target to shoot on in prone, how about a 300 meter target reduced to 300 yards.
Tatgets are the way they are to accept the average ability of the average shooter. The great shooters, well they just shoot great! There is no reason the change the target system for prone for the few that shoot great, you will just run off more of the average. But what I was thinking here is that the matter of convienence in scoring, that the a target used at 1K like the MR65 target would be better, due to the fact that it would be a full 1/2 moa completely out the 5 ring, scoring the target for the target puller would be less complicated and most clubs can go with this because, your still using the same amount of frames! As for covering the black on a prone target, if it didn't, well the just turn the full face over and then you don't have that problem any more!
Like I said, I am just thinking out loud here.
