I can only assume some of you do NOT read the various gun mags of a few years back. There was quite a discussion on the matter of small pistol primers NOT being as toxic as Large Pistol Primers---especially for the indoor ranges that were starting up as housing & families were moving close to many of the out-door ranges, SO the idea thing was a sensible indoor range especially up here in Canada, for rain or snow we have no problem of getting there & shooting.
Once in a while when I have cleaned up at our indoor range I sweep up mainly .22 LR spent brass that is put away for selling to those that purchase the brass & that is money to our h/gun section or the gun club.
My best friend & a good shooter when it comes to 45ACP uses the NT small pistol primers & if by chance I will save a few I might find for him. Now I have used some of his loads & they were good, he uses mine with large pistol primers & still shoots well.
Once in a grey moon I will not one of two are with sp brass & since I am lucky enough to have a turret loader I will slide in a Small Pistol Primer, they do not fall out & with the same powder as the LP they shoot just as well no matter what the bullet tip is like.
True if I had a progressive reloading press & was frantic to turn out a maze of reloads THEN I CAN SEE THEIR POINT. Now this is Canada & as of 1950 we could NOT sell reloaded ammo for if someone felt they wanted to get at someone, they did not like, then sell them a few with double load & let the chap suffer.
It sort of happened to me. A chap wanted to try out my Full House PPC revolver with 38Spl loads. I told him to use the reloads I had fed him. Purly by error he put in a double load (accidently his own errior for a Double Load) & that was the end of my very costly PPC revolver. No he was not injured, but the gun was totally shot.
He failed to realize that most of us PPC shooter use light loads when in competition or practice.
