Here is about the best review that can be had with this bullet.
It comes from the CBA’s match results site:
First Place, Bud Lawry, Heavy class. 100 yd score, 198 6X, 200 yd, 192 1x
Action, XP 100, 30 Rem cal, Lilja 30 cal, 11 twist, 23″ lg barrel, Leupold 45X scope, rifle wt, 12 lb 6 oz
Load:
NOE 311365, 3 range scrap/1 mono type, 196 gr, nose .302, bands .311, X-Lox 2500 lube
Powder 24.5 gr, H4198, primer CCI 400, est. vel. 2050 fps
This combination, edged out a 30 Rem, using the Accurate Molds 311230e with 29.6 gr Varget. The 311230e bullet is a Accurate Molds, version of the Eagan 30 cal MX4 ARD

Ran nose first into a sizing die Blammer. Here’s an extreme example, the 311365 on the right has been run into a bump die Smokem Joe made for me, in order to get it to fit right in my tight throated K31. The ogive on it is .299 the lead edge of the top band is .3055. Don Eagan also made a straight tapered die, some European standard taper, I’ve found, and some of the guys use them. Whether or not the bullet would need bumped for the 30Rem would depend on the throat configuration. The 30Rem has a plentiously long neck, almost as long as a Krag. The casemouth would be about the middle of the upper driving band when the check is at the neck/shoulder junction.

Bumping as we understand it refers to increasing the diameter either of the driving bands(body), the nose/bore riding section or both; by shoving the casting into a die of greater inside dimension than as-cast. You get a shorter, fatter projectile. Hopefully it will be dimensionally more correct a fit to the inside of your barrel.
What he’s doing is reducing the bore-ride/drive band esp. in the transition from nose to drive bands. The idea is to match the taper fit more exactly to the angle and dimension at the origin of the lands. Sizing, not “bumping”.
Please correct me if this is wrong?
I traded Bud my 311365 for his 314365 because he’d bought the 314 after I shared a post here that showed a 311365 pic–I was gun-poor at the time and I’d expressed a desire to try it in my Mosin so he bought one to try in his springer (we shoot Military at Clark). It required too much sizing to work in the tighter springfield barrel (and the 30BR chambered lilja on his XP100). I then got the 311 version and we swapped.
Never one to let success be left alone he’s off into another bullet entirely (an LBT mould that I think will be way too long to work in his 11 twist gun).
I have requested a 309365 in the “want to see ran” threads but no response from the sweed as yet. We tapered my remaining stock of 314365’s that I made up for the Mosin–I’ve decided to leave the x54 alone for now (the next couple of seasons) in favor of a nicely sporterized M1917 winny– 30-06 tooling being abundantly available whereas the x54 stuff is a custom proposition, mostly. I shoulda bought reamers when I started down the Mosin path so I could have made custom dies (Wilson seater type) but alas, I was too cheap to save money that way!

No, your not wrong.
Correct me if I’m wrong but, doesn’t “bumping” also apply to tapering a bullet to match a throat configuration? That’s how I was reading it.
When it comes to sizing, most people think of it as reducing diameter in a parallel form.
