The last time I shot Silvertips into wet newsprint at 40 yards from a 1006 and 1086, they expanded to .81 inches...

There aren't ANY "modern" bullets that do better than that...

That's more than doubling in size.

Realize, 10mms have more advantages over .40s than just raw speed.

The case length makes them very, very, very reliable to feed and eject. Actions have lots to lock onto.

In all the 10mms I've ever owned or shot, I've never, ever seen one actually "jam". 1006s are the best of the lot -- from what I've seen.

Can't say that for a .40 -- by a long stretch.

Plus, a 10mm is inherently the most accurate round I've ever seen.

I love .45s and 4506s -- but, please, don't try comparing them to 10mms and 1006s...

A 10mm has more energy with a Silvertip at 100 yards than 95 percent of .45s have coming out of the barrel.

Silvertips still are the "gold" standard -- like it or not. They're just hot enough -- plenty accurate -- well made -- available -- reliable -- and fairly cheap.

I'd own and carry 4506s -- but for what a 1006 will do in comparison, it's still almost always my first pick -- with Silvertips.

Most of the "real world" speeds I've seen on STs have been around 1250 fps out 1006s.
