Be careful saving too soon.  Some corrections will come.

Corrections AND more bullets.  I have 115gr HAP and Missouri Bullet 125gr SWC at home that I haven't measured yet.  ;)

Blue Bullet Coated
125 RN    .606"
147 FP     .665"

These had more bullet to bullet variation than I've seen before.   RN were .600 to .612.   FP were .662 to .670.   Nothing else I've checked had more than a .004" ES for 10 bullets.

That is a LOT of length variation.

My BBI 135 had a spread of .011.


Well, I find all this information about the blue bullets annoying, mostly because I ordered 500 each of those two Blue Bullets earlier today.    :P

You have this one listed already.    But I get the measurement a tad shorter.

BBI Coated
147 FP  .665   ES was .004" for 10 Bullets.    I think the mold for these is the same as the Blue Bullet 147s.    Push test in my CZ85 differed by .002"

Most likely due to the powdercoating on the bullet.  It doesn't get applied evenly every time.  IDescribe and I discussed this issue before with other types of coated bullets.

The bullet diameter should all be consistent, since they are sized after coating.

Both have a slight hollow back.

Updated for typo.   It should have been "FP".   It was very interesting that both of them pushed the same in my CZ85

I'm buying as many different coated bullets as I can.   Here's some data I've compiled.   Push test is in my CZ85.   I won't use the Precision 147s as I have to load them too deep
