I am looking for a very frangible 10mm bullet between 130-160gr. The lighter the better. Any great accuracy loads out there? I'm using a S&W M-610. Thanks.

There used to be loads that were pellets inside a jacket I believe,,,a safty slug,,Glaser Safty slug I believe????only loaded ammo,,,,I have never had good acceracy out of lighter than 165 grains in my glock.

The Glaser would be too costly and would probably not deliver the accuracy needed for varminting at long range. Thanks.

All the reload info that you could ever need for the 10mm can be found @ http://www.glocktalk.com scroll down to the 10mm Reloading section.

My top velocity load out of a stock 4.6" Glock 20 with 14grs of IMR 800X and Nosler 135gr HP bullets gives 1650fps, 1850fps out of my 6" Barsto barreled Colt Delta Elite and 2070fps out of my 18.5" barreled T/C Contender carbine.

I found this load on Glock Talk in the forum I mentioned earlier.

Thanks for the info. I just joined Glock. I have not tried 800x yet. So far it has been BlueDot, AA-7, and 231, All have been accurate with the 135 Nosler. I am seeking the absolute in pin point one hole capability. Nosler stated that a starting load of 12.2 of AA-7 was their most accurate with that powder but I started at 12.gr. and had severely flattened primers. All guns are different. My 610 said too hot.

From spending hours searching the net for 10mm reloading data I have found that IMR 800X is the very best low pressure top velocity powder of them all.

It is not the easiest powder to work with in a powder measure though, I got around this by installing a powder baffle in mine. Very accurate loads as well.

When on Glock Talk be aware that a fellow named Mike Mcnett is the guru of all 10mm load data and the owner of Double Tap Ammo.

Thanks for the info. I will try 800X. Problem is that I am pushed for time on a upcoming varmint hunt. Looks like I may have to go to 231 for now as it tested most accurate of the above list. Sound like I am missing the boat but for now I have no time left for other load development.
I will get to the 800X soon I hope.
Will try to let you know.
Thanks again.
