Make sure the case isnt swaging down your bullet.

But only IN FRONT OF the lube groove.
Sounds like the driving bands are still right at .452" where they should be. So that isn't it.

That was certainly my guess.

But the bullet resizing to .448 could be traced back to your sizing die. Pull and measure a bullet after insertion and before crimp. I did not get any improvement in maintained diameter until obtaining a larger expander plug, which is .452 instead of .451.

Sounds like he's got that squared away. He pulled a bullet and reported...
Hard to argue with that being the appropriate diameter at the driving band.

He said he pulled a bullet after crimp...too late to trace back to sizing. He needs to pull after seating.
The bullet should never be .448 inside the case.

So you're saying the bullet's driving bands sprang back to .452" AFTER he pulled it back out of the case?

Are you serious? I think there is confusion about his terminology and his measurements. There is no way the bullet is smaller outside the case mouth.

I was serious when I read what he specifically wrote. You seem to be assuming that he can't take accurate measurements.
He didn't say the bullet is .448" inside the case, except right at the crimp. Behind the grease groove it measures .452" -- AFTER he pulled it out of the case.
Maybe I'm misunderstanding what you're suggesting is going on?

Went to the range today. Shot 32 rounds of my 5.5gr titegroup 185lswc bullets. Higher recoil than the unique. No leading
.
Tonight I will try a 4.5gr load of red dot in my 230gr lrn and retry tomorrow. I will also try a 4gr load in my 185gr lswc bullets.

Actually I would recommend 4.0 gr for 230 gr LRN and 4.5 gr for 185 gr LSWC.uglysteve said:

His "forward" and "behind" are relative, so your inference (or mine) may be mistaken. However, .448-.449 is precisely the measurement I was getting, when bullets were smaller after loading than before. That portion was inside the case.
I doubt I can be quoted as having said anything about his measuring capability.

Ok, so you assumed he meant "forward" meaning the rear of the bullet, inside the case?
I guess it is all relative. Some cars have the trunk in the front, so I can see how back and front might be confusing.

Again, it's not logical for the portion of the bearing surface outside the case mouth to be smaller than the portion inside. That is the basis of my interpretation. I think you should ask uglysteve.

Did you still have a portion of the bearing surface extending beyond the case mouth? That should be either the original diameter or slightly mushroomed larger. If not, I think your OAL is too short, swallowing too much of the bearing surface and possibly swaging the bullet's last hope of sealing the barrel. Hopefully, your gun doesn't require it that short.
