Just got a sw 1006 10 mm. looking for a whitetail load..factory ammo?
Also what would b a good bullet for handloading

I like the 180 grain xtp's 200 grain nosler in the 100 rd packs.
handloads.com has alot of 10mm data but it is user data and alot of it is to hot. For plinking ammo I use GA Arms. They load decent ammo and use starline brass so I don't have to seperate brass. Double Tap makes the most powerful factory ammo and it is accurate in my glock.

Other options for your consideration; Buffalo Bore, Underwood, and Cor-Bon. As previously mentioned, DoubleTap is a good choice and they provide more 10mm offerings than anyone (16) Best of luck with your 10mm.

Hornady 180 gr. XTP, and 175 gr. Winchester silvertips have worked well in the past.

I like the 200 gr Hornady XTP. CCI 350 Primers with 8.6 of Blue Dot. COL 1.26. I have excellent accuracy in all my 10mm. The Glock 20, Kimber target, Dan Wesson And S&W 610. Killed MN deer with it and wouldn't be affraid to use it on Bear.

Reed's Ammo has quite a few options if you don't load:
