Ok, I received my 180 grain pulled HST's. I loaded up a few test rounds and shot them across the Chronograph. Test gun used was a Kimber TLE II 10mm. Chronograph used was a Chrony F1 from approximately 10 feet. All rounds were individually weighed and trickled.

I also loaded some up to 9.1 grains of IMR800X but did not fire them. The 8.9grain load was already higher velocity than what I was looking for. My absolute favorite load was with 8.4 grains of 800X and Winchester WLP primers. This was hands down the most consistent load of the bunch and gave me an average velocity of 1247 feet per second. My target goal speed was 1250fps. All other loads above 8.6 grains began showing inconsistent velocities. One thing that really stood out and can clearly be seen with my posted results, is how much of a difference it makes to switch from Winchester WLP primers to CCI 300 primers. Otherwise identical loads routinely ran 40 to 50 feet slower with the CCI 300 primers.

Is that a 5" barrel?

Yes. It is the factory 5" Kimber barrel. Only thing I have changed on the gun has been the firing pin stop to an EGW flat bottom and the recoil spring to a 22lb unit.

This is definitely interesting and noteworthy information. It's awesome to see the numbers side by side, thanks for the report Dieselman!
My original post must have not have made it to the forum. :o
Dieselman, thanks for a great report and it clearly shows what the change/swap of components can do to a given load.
The Winchester primers are stated as being able to be used as standard or magnum primers.
Thanks
I would have liked to have loaded up some tests rounds with CCI 350's to try alongside of these, but I didn't have any on my bench the day I loaded these up. I usually don't use Winchester primers because CCI's are generally much easier to find locally where I live. However, last year during the shortage, all I could find was the Winchesters. Since then, my local supply house has gotten a large stock of CCI primers back on the shelf again. So when I run out of Winchesters, I will switch back to CCI's again and compare them over the chrono to see how they measure up.
While I was out trying these HST loads, I also fired a few factory loads from the same gun for reference across the Chrony. Here is this data for comparison.
Remington UMC 180 grain FMJ -part #L10MM6 - Fired 4 shots
Low: 1118 fps
High: 1144 fps
Avg: 1129 fps
Underwood 180 grain Speer Gold Dot - part #244 - Fired four shots
Low: 1340 fps
High: 1348 fps
Avg: 1344 fps
Buffalo Bore 220 grain Hardcast - part #21C - Fired four shots, but only three registered on the chrony
Low: 1190 fps
High: 1197 fps
Avg: 1194 fps
Lastly, I also had another handload that I fired across the chrono and I will include this data here as well. This load was Blue Dot under a Hornady XTP. 10 shots fired.
180gr XTP JHP, 10.9 gr. BLUE DOT, WLP, Armscor brass, 1.255" C.O.A.L.
Low: 1297 fps
High: 1332 fps
Avg: 1307 fps
On an earlier trip out to the range, I shot two of the above XTP loads and two of the Underwood Gold Dot loads through 4 layers of denim into well saturated phone books. I didn't tray to record penetration into the books because its difficult to be accurate with this medium. i was justly looking to recover the bullets and see what they looked like. So here is a pic of that as well.

I am really looking forward to getting an opportunity to try shooting these HST's into the same medium for comparison. I have fired my .45 and 9mm HST through denim into wet phonebooks with some very impressive results!
How's accuracy?
Any target pics?

I think accuracy will be pretty decent. I need to set up some paper targets and do a formal accuracy test. I only shot these at a steel gong and soda pop cans on my last trip, so I don't have anything to show you
