Re: Advice on Reloading
This........increase the flair till a bullet can stand in the case by itself and sits about 1/16 under the case mouth. If you get any lead shavings increase the flair. Then you have to crimp the flare back at your sizing die. Put a sized case in the bullet seating slot and screw the die down till you feel it touch. That will get you close. Adjust the crimp till the bullets easily drop in the chamber with the slide open it should fit flush. The bullet should also drop out when you tilt the barrel up.
In general you don't want the bullet to touch the rifling or pressures can increase. The easiest way I found is to get a dry erase marker, blacken the bullet and gently push it into the chamber. If you see the rifling marks on the bullet it is touching and too long. This can also be the reason it doesn't pass the plunk test. The bullet may be jamming up in the rifling. Every bullet has a different ogive so you can't use another bullets recommended OAL.

Re: Advice on Reloading
Although 9mm technically can go out to 1.158, some euro guns like CZ and Walther will not like that and will choke on it. I pretty much don't go over 1.135 for 9mm

Re: Advice on Reloading
Lead bullets are larger than the FMJ that your powder funnel/expander was designed for.
Sometimes more belling will help. Sometimes it won't depending on the bullet.
There are aftermarket powder funnels for lead bullets that mimic the "M" die. Instead of just belling the mouth they evenly expand the whole neck. They can be ordered in .001 increments.
I fought the lead shaving issue with cast bullets with the factory SDB expander. Some brands worked and some didn't. I actually had the best luck with steel valley casting bullets. Ron is a member here. I cast most of my own now but if I was buying them that's what I would buy.

Re: Advice on Reloading
I never saw the point of a dedicated case gauge. The chamber specs are standard but like others have mentioned there can be a big difference in freebore before the bullet engages the rifling. That can depend on the manufacturer and no case gauge can tell you what is correct. As long as you fully resize a case in the sizer die the case is back to SAAMI specs. The only time you can have a problem is if you neck size a case that was shot in a longer chamber and try to shoot it in a tighter chamber. But you should never do this. Only neck size bullets for the same rifle. If you shoot the same reloads in more than one rifle fully resize all cases. This means turning the sizing die to touching the shellholder and then another ~1/8 turn. You should feel a slight bump then the press is fully extended. Seating a die to touch the shellholder without a case may not fully resize the case. There is a little spring under load and the case may not fully enter the die.
Checking every round is excessive. If you are worried check a few in the actual chamber while you are setting up then load away. I have loaded tens of thousands of rounds and never had any chambering problems if everything is set up correctly to begin with.
The OAL length you see in reloading manuals are rarely correct. And European firearms do not always conform to US SAAMI specs with regard to throat length. I have in my reloading notes the length to the lands for just about every bullet /firearm combination of everything I reload for. The fastest (and cheapest) way to find this is to take a fully sized case then take a dremel and make 2 cuts in the neck where the bullet goes. Blacken a bullet with a dry erase marker and seat it long in the case (it should move in and out with little force). Then insert it into the camber and seat it hard with your thumb. When you take the case out the bullet will be seated by touching the lands and you will know your max OAL. Seat your bullets 0.025 shorter for rifles and maybe a little shorter for pistols as long as they can still fit and feed from the magazine. Some firearms have excessively long throats.
Using this method sometimes the bullet will get stuck in the lands a little and get pulled out some when you extract the case. That is what the dry erase marker was for. Put it in your calipers and reseat the bullet till the black dry erase markings meet. That is you Max distance to the lands. Check all of your 9mm's and find the shortest throat then develop a load for it. That load will be safe in the pistols with longer throats.Last edited by Delkal; May 3rd, 2020 at 11:25 PM.

Re: Advice on Reloading
Same here but I only make 115gr RN in 9mm. They shoot well in my Walther, SA, Glock, Sig and H&K 9s.
I only plunk test the first few rounds of handgun ammo after changing the setup on my 550. I have toolheads for all of the calibers so it's a pretty much perfunctory check. I have a good case gauge for 223/5.56 and do use it on every round of those I make and I measure every powder charge for them as well. I had a problem with the resizing die not fully reaching the base of some 223 rounds that I discovered using the case gauge. I called Dillon about it and they said it was OK to overtighten the resizing die by as much as 1/2 turn to make sure it covered the entire cartridge length. I did about 1/4 turn and that solved the problem.NRA Life Member
