Using comparator tool when seating projectiles.

I'm saying you can't achieve that level of consistency without understanding the variables (and their effect) and then ensuring you manage that variable in order to control the effect of it. In the case of the OP, having a Micrometer Seating die is great, but only part of the answer to consistent CBTO (which is what is wants to achieve).

My reloading process is no different to that of countless others. It isn't special, it just works to manage the variables to optimise the outcome.

Lol, tight fat neck and then a skinny not so tight neck....dude, this is the subject of precision reloading practices to get the most out of a rifle, not hillbilly reloading for "minute of deer accuracy"! But for your future reference, consistent neck tension can be easily set with a sizing die and a mandrel, so neck tension is the same for all pieces of brass, irrespective of your tight-fat / skinny-not-so-tight necks.

hillbilly now.......
yeah lets just leave this alone before it gets personal shall we???
I shall go fill my freezer with round loaded on LEE whackamole uusing projectiles made before you were born and 760 powder that has been around for just as long..and be happy....
your CBTO is fine and dandy but your still intoducing a CBTPB error..no different to anyone else no matter how flash harry your gear is,either the projectiles are all the same or they are not,no matter where or how on the projectile you push..you are still pushing it from some point,and if they arent all the same,the finished product wont be either..its not enough to worry me.

Just because you don’t understand something, doesn’t mean I’m wrong ;-)

Keep an open mind Micky and listen to what’s being shared. You might just learn something.

right back at you

Greetings @Micky Duck,
I am with you on this one. I don't bother with a lot of the steps that others may feel are essential. Projectiles vary in their shape slightly over the years of production and sometime from box to box. Projectiles in a single box are not all made with the same tooling so vary within the box. Custom made projectiles can be better but well beyond my price point. For the reasons above I usually seat projectiles at a reasonable distance from the rifling, say 1mm or often more. I also check each batch of projectiles to see if anything has changed. From time to time it has and the die is reset. With target rifles small differences in seating depth can make a large difference as @6x47 reported above but with production sporter rifle like most of us have not so much. Never a particularly patient person I just can't be bothered going through a lot of busy work for little or no return. It takes an awful lot of shooting to reliably prove any improvement from tiny adjustments. A lucky three shot group does not cut it.
That said some may delight in endless testing and who are we to rain on their parade. Early on my loading technique was very basic as were the how to chapters in the loading manuals. A lot of the kit in use today did not exist. Today a how to description could fill volumes. Accuracy has certainly improved but how much of this is due to the whizzo kit is open to question. Each to their own.
Regards Grandpamac.

Thank you, gentlemen, for all the input. Some excellent pointers that I'm putting into practice. I have been well informed and also entertained.

@zimmer. I forgot to mention that I did try Alex Wheelers method. Found a massive disparity between Cortana's and Wheelers. Wheeler's served to help me set up a die properly though. Was an experience reassembling my bolt , the ejector pin shot around the garage like a blowfly on steroids, not once, but twice. Yes I found it the second time too.
