On Shilen's website, the difference between a "Select Match Grade" barrel and a "Match Grade" barrel is clearly described.
And true match grade shooters do know their differences and how fast that they can wear to the point of losing their "Select Match Grade" edge.
Shilen's select match grade barrels are air gauged to have a bore within .0003" of standard diameter with .0001" uniformity,
while Shilen's match grade barrels are air gauged to be have a bore within .0005" of standard diameter with .0003" uniformity. --->>>

If you would care to address the issue of how you went about air gauging your .45 barrel both before and after you began shooting conicals out of it
without experiencing any barrel wear, then I'd enjoy reading all about it.

Rattle down a bore?...come on thats nonsense and if you knew anything about conicals you would know there are many of them that are far from undersized. Such as Great Plains, Maxi balls and REALS. Its far from the "norm" for conicals to be slip fit.
Here is a great PRO for a lead conical.....No short starter needed even if its .002 over land size....How do i know....I actually do it....Not just copy and paste something ive read. When you actually DO something its easier to spot the BS posted on the net.
Did you ever read a Sam Fadala book where he wrote about 200 shots generally being needed to break in a muzzle loader barrel or even wonder why he would write that?
He clearly meant that a new bore can often need to be broken in or worn in. which also means that he believes that shooting it promotes bore wear.
That's the same reason why people lap their bore to break it in faster instead of by simply shooting it.
Yes, generally conicals do become relatively looser in the bore once loaded past the muzzle crown compared to sabots, and conicals generally don't seal the gases as well which can lead to more gas blow by, gas cutting, erosion, and barrel abrasion with its associated wear from heat & powder residue blowing by it.
It's obvious that one single sentence from Randy Wakeman in opposition to your opinion was just too much additional evidence against your opinion so now you feel that you need to make more personal attacks.
We can agree to disagree on the wear issue and the looseness of "pure" lead conicals once rammed down into the breech where the heat erosion occurs.
But know that there's different reasons for erosion and abrasion as I already alluded to previously which you understandably don't want to agree with.
However you really should stop acting like a Cyber bully, mind your manners and stick to the topic.
I've been a member of this forum for 3 years longer than you have and object to your personal attacks just because you disagree with an opinion.
