Two reload bullets can be twisted...a bit pushed.

[Ignition Override]

The cases were all neck-sized as usual with the same ".303 Brit." Lee die setting. I've done over 1,200 reloads with .303 cases and the same batches of bullets.

Two of these bullets might be a bit narrower than .310, and came from the same can of pulled .310 Russian bullets, which I bought from GB a year ago.

When seating the bullets, these two did not offer nearly as much resistance as most. They can be pushed into the case a small bit, but only pulled out (with my fingers) to where they were originally seated tonight. A little bit of force is needed to rotate them a bit.
Would these normally be considered safe to shoot?

Assuming that everything else about the cartridges looks OK, I'd probably consider them safe for range use, IF you segregate them from the other ammunition you're using and are extremely careful when chambering them. Ensure that the bullets aren't shoved down into the case when you push them into the rifles chamber. If, for some reason, you have to unchamber the round, keep the muzzle pointed straight up (assuming range rules allow it) and control the case with your fingers as it comes out of the chamber. That way, in the unlikely event that the bullet engaged the rifling when chambered, you won't fill your action with spilled powder. Make sure you remove the stuck bullet before you chamber another round!
A better option would be to adjust your crimping die down a little and give those two rounds a bit firmer crimp. I got 4000 of what are probably the same bullets from Wideners a couple of years back. The crimp grooves on mine are cut and are both deep and wide, if your crimping die won't give a good crimp in the groove provided, just pull the bullet out a few thousandth's and crimp into its side. Be careful when doing this though, because it's easy to deform the shoulder of the case, preventing it from chambering at all.
Unless bullets are grossly undersized, they are unlikely to cause any damage to your weapon when fired (even with very undersized bullets the possibility is remote, though quite possibly somewhat greater with steel jacketed, steel core bullets like your LPS ball). Accuracy and durability may suffer, so I'd still keep those rounds separate and use them on the range for shots where gilt edged accuracy isn't required.
Take care, be safe and shoot well,

I think the worst that can happen is the primer firing moves the bullet forward. Slow burning powder may not burn correctly with* bullet movement. Placing each round into the chamber should work ok to fire them. Measure the neck diameter of the loose bullet rounds. Smaller than the other normal rounds, would seem to be thin neck wall diameter or undersize bullets. Lee Collet neck sizing die being used??

A half thou difference makes a big difference in bullet grip but they will be quite safe to shot.

Thanks very much.

All the equipment is single stage Lee, and the concrete block won't know the difference.

Are you using a crimp for some reason? Just asking, because neck tension issues seem to be a relatively common problem when crimps are being used on bottle neck cartridges.

I had this same problem. The Lee dies come with an expander for 311-312 diameter bullets. Using 310 bullets won't give you much neck tension. Luckily the factory crimp die that comes with the set will crimp enough to hold them in place. They shot really accurately for me too.
