I'm always amused by authoritative-sounding posts based on a false premise. None of my reloads for any of my firearms are "interference fit."
I have no idea of how you reload or the quality of your reloads.
But on the firing line I have kicked out a number of rounds that were insufficiently sized by the shooter. These are typically new shooters, they buy a match AR15, which have tight chambers, the brass they are firing are range pickups or once fired military, both types fired in huge chambers, their standard sizing dies do not reduce the brass enough, and they have failures to extract.
The worst is when they can't close the bolt to fire their AR and the unfired round is stuck in the chamber. Then we have to put the safety on, disassemble the halves, and then we try to figure out where to go from there.
Knocking out loaded rounds with a cleaning rod have caused injuries when the round comes out and the primer hits something. Knocking out loaded rounds out of a firearm is something that needs lots of thought.
If you have not seen jams from "interference fit" cases then shoot twenty years of High Power Rifle matches. You will see a few.[/QUOTE]
Or having it be the second, third, or fourth round in the magazine of a bolt action while the hunter is in the midst of a pack of hogs. Trust me with adrenalin pumping, and the bolt handle being racked to cover a second or third shot, one can cram a round into a chamber more than tight enough to ruin a weekend hunt. Better yet, as mentioned above, is the driving out of the stuck round. In one case where it happened to me, I was on a week long hunt, ruined by one round of ammo, 15 minutes into the first day. Yep I got it out, but it took driving the bullet back into the case, after which the rifle had to be tilted muzzle down and the bullet held up to allow the powder to pour out. Once that was done then we could get a solid hit on the bullet which deformed plenty in the case making even more of a mess.
It all came out with no damage to the rifle, but it was more than enough aggravation to easily cover the cost of the SB die to make certain it never happened again.
But to each his own. I still check my rounds now as I did before and they chambered fine even the one that stuck. Where I messed up was I didn't chamber it from the magazine giving it a chance to load from any angle, or with any resistance. Once I tried that with the rest of the box I had loaded nearly half of them wanted to stick as I closed the bolt. Knowing what to expect they were easily knocked loose with no issue. Now they are loaded into the magazine and chambers as if I am taking multiple shots one after the other as fast as I can rack them through. Witht he SB sizing I have not had another instance of any of them even being close to a snug or tight fit.
Take it however you want, as mentioned if it hasn't happened, you haven't been shooting or loading long enough. I've only been at it for 40yrs, and had it happen to me three, maybe four times in all of that. The worst however was as mentioned above on the first day of a week long hunt. It would have been even worse had I been in a SD situation where myself or my family might have been at risk. I don't worry about that anymore either.
You probably don't need small base dies. I've reloaded tens of thousands of rounds of .223s for shooting through my ARs. Never needed a small base die, and my ARs never fail.
