That hammer gizmo will make anyone crazy in a hurry, couldn't wait to get rid of that thing.
I also use the RCBS collet bullet puller with good success.
If I want to save the bullets (Not that the collet will ruin them)I sometimes make a collet that Is a perfect fit so it does not deform the bullet in any way.
The factory collets are fine but don't always fit perfectly, and when I use them to pull bullets
I use those bullets for break in and sometimes for load development.
They appear to be fine as long as you don't crank down on the collet, but for accuracy testing I prefer to use fresh bullets from the box. Unless you are shooting matches or extreme long range I don't think you will see any difference with collet pulled bullets if you are careful pulling them.
The impact pullers are ok if you place an ear plug in the nose of the hammer to protect the bullet.
I carry the hammer type to the range in case I have a load that is to hot and don't want to take a chance on getting it mixed up and firing it.(It is safer to just un load it).
I used to pull the 173 grain match bullet in the 308 white box match and replace them with a 168 grain SMK (Hundreds of them at a time) And the collet puller was the only way to go, especially if you wanted to save the powder.
