Talley one piece- My lapping experience

I bought these Talley mounts for my .260 build on a Remington 700 action. I searched for information about lapping and got differing opinions on everything I read. Ultimately, I chose to lap mine for piece of mind and I didn't want to chance ring marks on my new Vortex. From the pictures, you can see that this was the correct decision. This is not a knock on Talley but just an example of what can happen when you mate mass produced items that are not custom matched to one another. Being a machinist by trade, I can say that just because the Talleys are CNC machined doesn't guarantee perfection. You still have the human element involved in tool and part setup. It is also well known that 700 actions have their share of imperfections. For these reasons, I recommend lapping regardless of the make or style of mounts you choose. I think the Talley mounts are an excellent choice for a solid, affordable mounting option and lapping will ensure that they are the best they can be.

Mounts will not any truer that the action, check the top of the receiver and you will find problem.

Yes, I am aware of the problems with the action as mentioned in the original post but you can't fix that unless you redrill the holes. The easier option is lapping.

For a 40 lb Bench gun shooting Bugholes at 100 yd...a must. For a hunting rifle shooting less than 1" groups at a hundred yards...all in your mind.

From an accuracy standpoint, you are probably correct. However those ring marks on your $600 scope are very real.
