Thought I wasted my money but I was wrong.

After getting into the realm of the .300 WM, I was lead to believe that I would need a collet sizing die to be up to snuff. I spent $150 clams on a Reloading Technologies die. When it arrived I checked the REM, Fed, Win brass I was reloading with the go/no go end of the die and it was all fine. I thought to myself, what a dope for wasting $150. The above brass was only lasting for 3 or 4 firings before the primer pockets became too loose to use. I upgraded to Peterson Long brass, it’s the best brass I have ever used. Today on the 5th firing, I noticed stiff chambering. I was surprised because my sizing die was set up perfectly and had been working just fine. I dug out my fancy die when I got home and discovered my brass was now all a no go. Reread the instructions and resized it all the way down to the belt. All ago once again. Sooo, if you have quality belted brass, one of these might come in handy. My Peterson Brass is going on its 6th full pressure firing and this is the only issue so far. Dare I say a happy 4th to you all.

I have a similar thing. Use it on every reload.
Larry Willis thing - excellent vfm considering I’ve been reloading for over 10 years.

Well done that man and just great awesome that your solution coincided with the anniversary of that little local difficulty sooooo many years ago….

I used to use Lapau and Winchester brass , the Larry Willis die was a very effective cure for the swelling .

Larry’s die is marked under the Reloading Technologies name now. My die is one in the same.

I started out using the Larry Willis (Reloading Technologies) on SAKO cases for my .300 Winmag. I got over 10 loadings before retiring them. Primer pockets were still tight but the necks were beginning to split on the odd one, so safety first.
Went to GECO brass, and same again but with less neck splits. Now on LAPUA brass which interestingly is just beginning to show loose primer pockets, so it’s ready for retirement after this lot have been shot.
The no/no go gauge and then the collet resizer is a really handy piece of kit to have.

I bought one after I had a case head separation in .375" H&H on a double rifle. Since using Larry's die I've never had a case separate near the belt. What was interesting on the separated case was the amount of thinning of the brass as the case stretched.
Now I understand that Doubles aren't as strong or rigid as a bolt action so this may have been a factor but the die has paid for itself many times over, not just in saving brass but in removing the hassle factor that a separation causes so if you do have a belted chambering be it in a bolt action or double it's well worth considering.
