Hi Unregistered,
On July 29th, this site will be moving..! No, really - it's "moving" to another physical location - including servers, gateways, routers - everything - including my coffee cup...
So, from the date of July 29th through July 30 or 31 (shooting for these dates, but - as always, I'm at the mercy of my ISP who has to install the lines to the new location - and we actually get them running ;) ). But - this site, cloud servers and main web will be OFF LINE.
Now, please save these dates!! Please - don't be "that guy" who emails me on the 30th to tell me you "can't open the Parker Website". I'll already know it is offline - and also know that you are "that guy"...
I'll take this notice up and down over the next week or so - and leave it up during the final few days before shutting it off on the 29th..
John D.

Mike et al., I had some time and plugged .835" bore into my choke calculation excel spreadsheet and here are the theoretical constrictions for 8-gauge. As always actual choke efficiency (percentage in 30" dia circle at 40 yards) depends on other factors to include shot sizing, bore "roughness measurement", choke profile and others. Bottom line, there's no substitute for testing on paper.
8-Gauge IC = 13 thou
Mod = 24 thou
I-Mod = 34 thou
Full = 47 thou
X-Full = 52 thou

Good to see our numbers are only off by .001". Probably due to me using .846 instead of .835. THX!!
