I finally got slugged

[booger7777]

I just got through slugging my 92A1 Beretta, and it slugs @ 357. Do I need a bigger sizing die than .356, or will this work?

I would start at .358" Of the 9mm's I have, 3 get .358", 1 gets .359" Shooting lead through a 9mm at .001" undersize isn't likely to work well for you.

If you use the .356 sizing die the probability is, it will plead the barrel badly. You may do fine with .357 but probably better with .358.

356 and 357 will lead and shoot bad.
358 might work.

I use .358 in my Beretta 92Fs, and a couple of other 92's in the family along with a Taurus 92 clone with good success.

I have pretty much standardized all my 9mm loads at .358 since my results have been so good with it. It seems to work well in a wide variety of my other 9mm pistols as well.

Some have reported success going smaller, and others have had problems. As long as .358 will readily chamber for you, (and it should) I would try it due to the results of your slugging. With your bore size, I predict that the larger boolit is more likely to be accurate, not keyhole, and keep your bore free of lead deposits.

Thx everone, I will consider all advice which leans to .358...but one other consideration is that the 92A1 Beretta 9mm has very shallow grooves. I can't following the reasoning of firing a .002 larger through a barrel, as I would think it would try to resize the bullet just like a resizing die and therefore leave lead behind. That being said, I acknowledge my inexperience, and will simply close one eye as I test fire.LOL. Now I have to buy another resizing die and will proobably just keep the .356 for future use, as I might be able to use it

For some reason the most available Lee push through sizers are often in the least useful sizes. Everyone would be happier if they would make their primary offerings 2 thousandths of an inch over jacketed diameters.

For example the sizer selection or 45-70 leaves a lot to be desired from Lee.

Dilly I totally agree. For 7.62x54r .313 and .314 would be WAY more useful than .311.

So I am honing mine out, slowly, carefully. I'd pay a couple dollars more and do without the alox if I could get the size I want.
But I can't see paying double for a custom one when I can hone out this .311 a thousandth or 2.

Lee are you listening? There are a LOT of Mosin's and Enfields that need .314 and .315 molds and push through sizers.

Normally, the barrel swages the lead bullet down regardless of "shallow" rifling. No big deal, and that's the idea; secure a tight seal between bullet and barrel by having the bullet .002" larger than the groove diameter.
