I have the same Ruger, new gun and new to 10mm.  Not to jump this post, and perhaps help both of us, any load info with this 200 grain lead bullet using Long Shot, or even Unique or 231? 

Thanks

Any suggestions on the same or similar 200 grain hard cast bullet, with Long Shot?  Have 1000 bullets sized .401, by only 1 lb of Long Shot, or lots of unique and 231.

Load data appreciated with this fine bullet.  Gun is a Ruger SR-1911 Target 5".  If I could find BD I would use it.  I have two XD autos, but none in 10mm.  Love the XD format.

I was able to get to the range the other day and here are my informal results, for those who my be interested.

My 180 Xtp's, seated ar 1.260 in mixed brass, mostly Aguila, began with 8.0 grains of LS.
Stout, but soft enough to shoot all day.  Only loaded 5.

8.5 grains LS, very slightly hotter, but noticeably louder.  My range has covered positions only 8 feet above my head, so everything I shoot is loud.  I've doubled up with insert plugs and 28 rated headgear for years.  A good thing! 

9.0 grains even was not particularly more harsh or louder yet, but after my very brief encounter, clearly has potential as the  best of the three.  Stout, smooth, controllable, and noticeably accurate.  Did not shoot on paper, but the very high dirt backstop at 55 yards had 100's or more various size orange clay target pieces on the embankment.  I love it when that happens.  From an informal rest consisting of a thick towel over 2 by 4 pieces of lumber, I was easily able to blast them with regularity with the 20 rounds I had left. Gun was new, first time out and the factory sights on this Ruger SR 1911 were regulated perfectly.  At 50 yards it was shooting 3 to 4 inches high.  Perfect. 

Will be loading the 50 I have again with 8.5 and 9 grains, with more emphasis on actual grouping on steel and paper.  Do love this firearm and cartridge.  Wish I had more brass to load 100 for each range session, but will have to shoot factory hard to find ammo up just to get more brass to reload?  Seems like an oxymoron to shoot loaded ammo to reload? 

Thanks for all your comments and input.  My 45's will be gather dust for awhile.   Jim

Thanks for your confirmation.

New to forum today. 

I've been reloading many handgun and rifle cartridges for over 4 decades.  Recently acquired a Ruger SR 1911 in 10mm with adjustable (Bomar Style) and a heavy target bull barrel with no bushing, slide only lockup.  A first for me as I have a number of Colt Series 70 government and Gold Cup configurations which obviously, all have bushings.  A question for another time will be is there an after market bushingless barrel available as I would like to go with a six inch at some point.  Might have the wrong gun to do that?

My first excursion into reloading the 10mm and was lucky to acquire 500 Hornady 180 XTP's, and equally lucky to find two 1lb canisters of Longshot.  I'm looking to build 1200/1300 (max) loads at pressures that will allow a reasonable brass life.  I have a number of 40 S&W guns, so I want to make fun to shoot relatively warm loads for 50 yard playing.  No desire for target loads when my 40's around for that. 

Seems the 9.0 grain LS should get me what I want?  Being the cautious type, I just loaded 10 8.0 grain, 20 8.5 grain and thought I would ask here before I went up to the 9.0 grain.  Plan on going ahead with 8.8 grains to finish a box of 50 then head to the range. Don't know the factory shipped spring weight on the SR 1911 but will research.  Guessing 22 lbs?

Fired 40 rounds of 200 grain 'Bear' rounds, only thing I could find, and I was chasing bass afterward up to 25 feet!  Was stout, but great to shoot!  I mean great!  I'm hooked!  My son  in law fired a magazine full and said it was a beast.  I would disagree.  Stout and very controllable to the point of coming directly back at me as opposed to my slow and lumbering 45's which like to rise as the muzzle.

Undoubtedly a redundant question here, but suggestions would be appreciated.  Stout, powerful and around 31,000 psi max.......assuming that is possible.  Again I have the XTP 180's and custom hardcast 200 fn.   Thanks for listening.
