I've got a couple hundred of these in a bag, but can't recall make and model. They weigh in at 64 grains. What do I have?

Looks like a 64 grain winchester power point to me.

I just measured some I have and the length is .81 as well. The shape is very similar too.

Mine don't have a cannalure but they were made both ways

+1

I was thinking Win PP, but didn't know they were made with and without the cannelure.

thanks guys!

You bet. The cannalure version went in to the winchester ranger LE round.

As others have stated, they look like WW 64gr power points...I never had much luck (accuracy wise) with them.
