I run them thru the sizing die to make them consistant , reduce their diameter and crimp on a gas check, but no lube. The bullet sizes to .457 and with tape comes back out to about .459 - .460. It sounds a little tight but the tape compresses very well and leaves the bullet once out of the bore. I have been thinking about getting a smaller sizing die to get down to .456. Because the tape is teflon it is a very good lubricant. I use no other lube with the tape. Leading so far has be almost nonexistant.
I like the tape because there is no sticky grease/wax, and with the tape the natural application is to stretch it to make it adhere which creats a thin film lube directly on the bearing surfaces of the bullet.
DO NOT CRIMP THESE BULLETS. It will tear the tape and render your 'patch' ineffective.
So far I like the way my gun shoots them. Like I said before, I still have a lot of work to do in testing, but so far they are very comparable to regular jacketed bullets - they just take more time and care to deal with.
