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.

Marc,
Contact BPI for their "10 GAUGE - 28 GAUGE LOW PRESSURE LOADS", Library # OOBLowPSI. Their loads for lead start at 7000 PSI.
For Nice Shot I selected a 6500 PSI load and added 1500 PSI due to shot hardness as advised on the Eco Tungston website. I need to contact BPI for the ITX safety factor. This is the fun part...
This ITX load is hot for old guns but my Little Friend Ten, a straight grip Damascus GH 10 was proofed in England for 3 1/2 tons or 10,500 PSI. This Parker is full pound lighter than my aforementioned DH 10. The DH of course has thicker barrels. Barrel thickness (and condition) is the key.
BPI L0AD#100907-2465-4/2/BB
HULL: FEDERAL 10ga. 2-7/8” (2.85”)
PRIMER: FED209A
PROPELLANT: HODGDON UNIVERSAL CLAYS 33.0 Grains
WAD: Helarco VP100
SHOT: 1-1/4 oz ITX #4 or #2, or BB (546gr.)
BUFFER: none
ROLL IMP: For over shot card use a COS12 or a N710 card.
Result: PSI 10500 FPS 1435
Wow! 1435 FPS...that's fast! So, back it down a few grains and switch to a Cheddite or Win 209 primer to lower velocity to 1200 FPS. The pressure should drop.
Mark
