I usually take 8 or 9 guns and stay for about 2 hours. I shoot a mix of carry/self defense weapons, and older guns that I enjoy shooting and reloading for. I fire 20-50 rounds out of each weapon.
Here's a list of what I fired last Saturday, in the approximate order that I used them:
Walther PP .22 LR
S&W M18-2 .22 LR (bought new in 1965)
SIG P232 .380 ACP
S&W M1899 Serial #225 .38 Special
Colt M1909 .45 Colt
S&W M625-11 .45 Colt
S&W 1911 PD .45 ACP
M1911A1 WWII vintage .45 ACP
S&W M&P 9 mm
And to finish up with a real bang, a Stoeger 12 gauge Coach Gun with Fiocchi 00 buckshot loads. I usually clean my guns after about 200 rounds, otherwise I'd spend more time cleaning than shooting. I always start with about 50 rounds of .22 LR and I use both bullseye and silhouette targets, mostly at 50 feet. Almost all my centerfire shooting is with handloads, with some factory 9 mm thrown in.
