Sorry if this is the wrong place to post this... Anyone have data/experience with how big a log it takes to resist small arms fire?

Depends on the wood, caliber, and time of year. (yes, trees change throughout the year. Sap levels raise and fall.)

Why do you want to know? Do you want to use some logs as a backstop?

If you want to stop bullets, put a gap between the wood. Plenty of ammo can shoot through a 4x4 piece of wood, but take two 2x4's and space them apart a few inches and it becomes a lot more difficult to shoot through both.

Hardwood is a lot different than softwood. The range here uses railroad ties. Real ones, not landscape ties.

As said- depends on the wood, green or dry, the ammo, angle of impact and distance from which it is fired.

I want to know because I'm thinking of building a log cabin, and I want to know if 12" diameter pine logs can resist small arms fire (assume less than fifty cal) from handguns and basic rifles...

Perhaps that's the answer I'm looking for, smaller timbers, with a 3" gap filled with concrete.. I like that, at least for the bottom few feet...

A 12 inch pine log will stop handgun ammo, and most smaller rifle calibers. HOWEVER- please remember that a wall built of ROUND 12 inch timbers is NOT uniformly 12 inches thick. Where a log is stacked on a log, thickness is about ZERO.
