Even though I don't shoot BPCR silhouette, I often wondered how the NRA decided upon the weight limit & other rules.
In any event, I can remember gun magazine letters to the editors & articles about NRA sanctioned BPCR Silhouette & the weeping & the gnashing of teeth that duplex rounds aren't allowed. @ that time (late 1980s), some claimed that the NRA BPCR Silhouette rules just were too "restrictive". I witnessed many a heated argument @ matches & BS sessions about the BPCR Silhouette rules.
Then we heard the same when the NRA decided that a duplex load was no longer legal for NRA sanctioned BPCR LR. Somehow though both sports still are w/ us--despite these "restrictions".....
In the "Black Powder Cartridge News", Fall 1999, #27 (pages 20-21), Bill Pace wrote an article about BPCR silhouette. Below are the first three paragraphs:
"A 'Limited Equipment' Sport.'
"Thanks AI and Doc, for BPCRS!
"When Carlson and I conceived of BPCRS, we thought in terms of very simple game without a lot of gadgetry, especially one that would avoid the usual equipment race you see in so many other shooting competitions. You know just basically a rifle-a Sharps or a Rolling Block-and the stuff a Buffalo Hunter would have had.
"AI Hill, NRA Silhouette Committee members and one of the co-founders of BPCRS, was speaking to another shooter at the 1996 NRA BPCRS Championships. I listened as AI talked about their early shooting experiments, how they arrived at rifle models allowed, and dimensions, etc. This was my first National BPCRS match at Raton and over the next three days I had an opportunity to consider and remember AI's comments.
"As the final day wound down and we gathered for the awards ceremony, I thought back over the past three days. Yep! Had a great time, met lots of people, and got to look at lots of equipment. Recalling AI's 'keep it simple, no gadgets' comments, I could only laugh."
The remainder of the article is a tongue-in-cheek look at al/ the equipment needed and/or perceived to be needed to participate in BPCRS.
