A big mahalo to everyone who helped me on this forum!

First off, I want to thank everyone on this site who provided me with reloading advice that I needed to put this article together. This is a follow-up piece on the original story posted earlier. For part two, I took the same stock, RIA Pro Match Ultra and tweaked it by adding a slide, an optic and grips. It's as accurate as any wheel gun I own at 100 yards. Hope you enjoy the piece. Any comments or corrections are welcomed.



Rock Island 10mm Upgrade and Review:  Caspian Slide + C-More RTS2 optic + Magpul grips

http://www.alloutdoorstech.com/ballistics/rob-kay/rock-island-10mm-cmore-rts2-caspian-slide/

Here's some results of load testing with a 165 gr HP Berrys over AA#5 and 8 gr of AA#7 over a 180 gr cast bullet. Both were bench rested at 25 yards.

You're absolutely correct...

I had a new G40 tricked out with an expensive aftermarket trigger and a barrel. I never liked the striker-fired trigger compared to a 1911. It simply wasn't as accurate or at least I could never make it shoot as accurate as a 1911. I showed it to some other guys in the club I belong to. They are all excellent shots. They agreed that the trigger stank compared to a decent 1911.

So I got the Match Ultra which can shoot circles around the Glock.  If you read my review that was posted on this site you'll get all the details.

Thanks Shadow...looks to be .401...I plan to shoot it from a 6" RIA Match Ultra...

Just got a bunch of bullets in attached photo. It's 180 gr that a local guy cast for me. I am starting with some AA#5 loads (7.4 gr and 7.7 gr). I also am taking a cue from this story which had some interesting ideas for AA#7 loads:

Will see how this works. I've got plenty of bullets so I'm hoping they'll be accurate at 100 yards.  Otherwise I'll have to give them away...

FWIW, it was suggested that I try the FBI load. Well I did so with a Berry's 165 FP.  Fairly consistent except for one flyer at 25 yards with a notched type rest on the bench. Not sure if it was luck or a great load. It was not as accurate at 50, or perhaps I didn't do as good a job pulling the trigger. Looks promising for this bullet.

BTW, the caption on the jpeg says HP but it was definitely FP. Mea culpa...

Thanks Shadow, I'm going to give #5 a try with some light loads. I'm really accustomed to the Bullseye scenario. Now that I'm hooked on a 6" 1911 10mm my next step (if I can figure out a load) is a 5" model that I can shoot like a milder mannered .45, if that makes sense...

Good input. So here's an academic query I have:

Do any of you have a light, target load with say a 180 gr bullet that I could try out with maybe #7 or #5 that doesn't have the kind of recoil usually associated with the 10mm?

In other words, something that approximates the classic "bullseye" load that you can get with a .45 (3.9 gr BE) over a 185 gr swc bullet that is accurate as hell but not punishing in the least? Or...am I asking for too much given that this round is more like a magnum?

mahalo

Appreciate everyone's input.

FWIW I can keep people posted on what I come up with in the load testing. I'm particularly interested in what kind of luck people have had with 6" 1911s and Western Powder products...As mentioned I have #9, #5 and #7.

Appreciate the feedback. I just called Western Powders and the guy recommended #5 with a cast lead bullet.  Will give it a try and come back to everyone. Was wondering if anyone had any experience with it...

I'm new to the 10mm club and just acquired a RIA 1911 chambered in 10mm with a 6" match barrel. I'm working on some loads with AA#5, #7 and #9.

I'm shooting mostly 165 and 180 gr HP and FP plated bullets (Rainier and Berry's) and a local guy will be casting me some 180 gr FP bullets with a conical shape like the Berry's FP's. My main interest is shooting longer distances--100+ yds at silhouettes or gongs rather than paper. (So far in testing loads at 25/50 yards I've found #9 to be the most accurate at 12.5-13.5 gr over the 180 HP plated bullets while 11-11.5 gr #7 works pretty well for the 165 gr bullets). 

Does anybody have any suggestions for the 180 gr cast or plated FP plated bullets? Does the 6" barrel figure into the equation?
