Resizing a round with primer in

[HALODIN]

It was FredB and also Mr_Logic said he's resized a few. I just found my old thread -

[HALODIN]

This was his explanation -

Halodin: I shoot a lot of 44-40 using 429" dia bullets. If I load using the conventional sequence, I always seem to get a round which is difficult to chamber---this always happens on a double tap sequence on turning targets. To ensure easy feeding, I adopt the following sequence: decap and clean case, recap case, add powder, neck expand, seat bullet and then size. The die settings are important: there needs to be just enough crimp for the sizing operation not to lift it completely so the feeding operation cannot push the bullet back into the case. I have to do exactly the same thing with my 300 Sherwood rounds. These rounds are long, with a small dia and are difficult to chamber at the best of times. If slightly oversize, the round will stick half way into the martini chamber, making it impossible to push in and difficult to remove. This is a single shot rifle and so crimp is not important.
On the other hand, I load several calibres without using dies at all! With 310 Cadet, the case is re-capped, filled with powder and the bullet thumb seated. This is a heeled bullet and cannot be pushed too far in. I do the same thing with 8.15 x 46R---this is a stop-ring bullet, and again, cannot be pushed too far in, but, I have two rifles in this calibre and the fire- formed brass is not interchangeable between the two---it has to be segregated.
You don't really learn about reloading until you get involved with obsolete calibres!

why? if size is that important to him surely it would be far safer to just resize fired brass and reload from scratch? even one cartridge igniting in a die would be a disaster why take the chance ?

I should point out that i have never re-sized a factory round. Other than .22 rimfire and a few 303s a long time ago (30+ years), I have never owned a factory round.

I asked the same question a few years ago and found decapping primed cases is fine, but you may as well have resized the brass with the primers in. I was really cautious the first time I did it, but after having resized dozens of cases, I couldn't find any concerns. Obviously wear safety glasses though.

Someone on here full-length resizes live rounds and IIRC has done thousands of rounds over decades and not had any issues. I wouldn't do this, but I think it proves a point with primed brass.

You mean he takes factory ammo and resizes it ?

Some folk may want to by surp ammo and fit a better bullet Bri. I have pulled RG ammo for my collection than reloaded the primed case with my normal load just to get shot of the case, keeping the bullet to go with another fully inert round.

As long as you are careful with the lube you could simply take the primer popping pin out and re-size, mine are all out anyway (apart from the Lee that I ground off) as I clean before I re-size so de-cap first.

Or use a lee collet sizer, get a more concentric neck and no lube required.

Some good tips here but be wary as a friend of mine has had a primer go off when priming let alone de- so make sure you wear eye protection
