The games of rimfire and airgun benchrest have been chronically infected by a pervasive need for each organization to have their own proprietary design of target. I feel this single fact has done as much to slow the spread of these games as any other. The need to try to preserve intellectual property and/or benefit monetarily through the sale of official targets is perhaps the underlying concern, but I have seen and experienced some of these issues firsthand over the years, and its for this reason I came to the conclusion that OUR club would do itself a disservice were we to follow suit in the universal manner.
Instead, we spent a bit of time researching whats really out there already, preferably a standard NRA model, available from more than one source of commercial target suppliers. Thus much of the political wrangling over targets can be eliminated by any wishing to give it a go.
When one can BUY good, professionally designed bulk targets for seven cents apiece that have stood the test of time and are readily available anywhere in the country, we saw little need to by proprietary, or worse yet, try to design yet ANOTHER "special". Now I had already been using this target for some while, but did the due diligence of searching for an even better one that still met the criteria. The A36 was still the choice for us.
Again, were I to show up at the World Match, I would absolutely fire on THEIR target with no qualms, as I would at the metric distances, but this really doesn;t seem to have any bearing on PRACTICING for the World's match, since firing on a tiny scoring ring is still involved (the ten ring of the A36 target we use is under a millimeter in dia) and we already shoot at 50 yards, which is close enough practicewise to fifty meters, and we could always put some temporary stands at 25M as well if we wanted.
One thing I learned many many years ago about serious practice on paper ... NEVER use common bulk printer type paper such as is mostly used when the target designs of others are copied at home, because it costs more to print them than it does to buy ready-made targets on decent stock and they don't produce cleanly punched holes unless they are literally glued to a stiff backing!
