I'm getting ready to place another order from Montana Gold and want to buy a case for the obvious saving $$. I'm going to start reloading 10mm for the first time and my 10mm loads will be just for fun as I don't hunt down here with the G29SF. I also reload for 40SW and have usually loaded 180gr bullets as they're softer shooting. I want to buy the same weight for my 40SW & 10MM loads and I'm torn between the 165gr and the 180gr. My predicament lies in where I have an MP5 clone in 40SW with a Bolt specific for 165gr loads. Will the 165gr work well for me for both 10mm and 40SW? I currently have Unique, and WSF on hand, but was thinking of getting a 1# of Longhsot or AA#9 for some full power 10mm? Any help would be appreciated here. Thanks Wanna kill these ads? We can help!
