How flush is the round with barrel hood?  If it is too far below say more than 0.002 below you may see cracked necks or even case neck separation.  Usually not so much with new brass, but subsequent reloads and reworking of the brass...

Looking good!

Here are pictures of my handloaded 9x25 in the chamber of my G-29 LWD barrel photo taken barrel chamber straight up.



Photo taken cartridge fully seated, barrel laying horizontal on table...almost zero gap at 0.000"

I gave up trying to hold the ruler level, but this is a factory Double Tap round and I have space. Not to mention most barrels if you try to stick a bullet in the Muzzle it catches on the lands. On my LWD 9x25 this round falls to the brass. Edit, nevermind the bullet was just seated deeply and the taper was throwing me off.

Its cool, DT and UW may be slightly overly sized and set he shoulders back some, when seated they show slightly below the barrel hood as loaded.  When I set my Dillon Dies on the RCBS press, the shellholder doesn't touch the bottom of my sizer die.  This keeps from setting the tapered area back too far.

I test the sized cases in the barrel as shown looking for flush barrel hood fit, to keep the neck from being overly worked between firings and sizings which can lead to case neck separation and splits.

I have plans to carry it as a semi auto 357 mag. 125 bonded Nosler at 1550

I went with the 124gr XTP, 16" of penetration and 1541 fps.
