Well, I don't know Charlie either, but if he shot IMHSA, then he's a kindred soul and just a crazy as the rest of us addicts.
Central Coast Silhouette Shooters out of Morro Bay CA in mid to late 80's was the reason my family was semi destitute.
The whole family was involved. Son was 13, daughter was 3, wife was young and hot and I was younger, uglier, and dumber than I am now but just as broke.
Wifey won the 1985 (I think that year...) AA Production .22 class for the CA State shoot. Still has the stainless Mark II 10" bull barrel. Eley Tenex didn't cost near as much as it does now. We were shooting upwards of 2 bricks of .22 as week in addition the my big bore efforts and a monthly match. My efforts w/ a Ruger Single Six w/ 10" (with one side of trigger spring disengaged to conform to production rules) was responsible for quite a few 1st place club matches and 40/40 patches.
I was also able to hit a couple of targets (60 for 60) and outshot a bunch of half blind, one armed, and deaf midgets in 1986 at Ojai CA at the Region 6 match (CA, OR, WA, ID, NV..I think it's changed up now) . They gave me a plaque no one else wanted.....
Used a TC 14" in 7 International Rimmed (30-30 necked down to 7mm w/ 154 Hornady), for the Unlimited class and a 10" in .357 Maximum for Production class. Still have them as well and shoot 'em once in a while.
However, old eyes are not useful for iron sights and the range closest to me w/ targets won't allow any handguns without a scope. Besides, the Chickens START at 200m at this range and that used to be the shoot off stage for all those that cleaned a 40/40 first round. I could hit most of 'em at that distance back then but hell, I can't even see 'em now.
I miss the competition. Good times and good peeps. Thanks for the post and recall of memories.
