N320 powder load

Good Evening,

 

I am starting to reload for the Tanfoglio Limited Custom Xtreme. I have VV N320 and 180 grain Blue Bullets.

 

The Coal I am aiming towards is 1.125, as for the powder load, this is what I have tested so far. 

 

4.0 Grains on N320 got me a PF of 160.

 

4.1 got me a PF of 162.

 

Need to make PF of 165 with a buffer, so I would like to be around 171-172. On the VV website, it says to do a max load of 4.1 grains with the N320. Is it ok to go above this?

 

Thank you for the help.

Check your mags for longest OAL they’ll accept and load to just less than that for OAL,  work your load up from there.  Yes,  you will be above published specs so you need to check for overpressure signs as should always be the case.  My limited chamber easily accepted 1.20” but that required 10mm mags.  With .40 mags your probably closer to 1.16” depending on bullet profile.  Use the search box,  you will find a ton of .40 load data using N320,  very popular powder.

Also, when reloading 40, is it common to not have rounds fit inside case gauge because unsupported barrels such as glocks? 
 

I am still doing load development. But, I do it in batches of 10. Sometimes I have 1 or 2 rounds that do not case gauge. Is it because I’m not roll sizing?

 

And, I was going to set my COAL at 1.124. Is this too short?

I use from 4.6-4.9gr of N320. Bu I also have a COL of 1.185". You'll have to increase you COL in order to go past the 4.1gr max. Most people load 40 S&W long in limited guns. 1.125" is too short for limited guns.


I use a similar load 4.5 N320 under 180 blue. 
 

My OAL was 1.14” since I shot in both CZ and 2011 limited guns. @Postal Bob long OAL may not fit his Italian limited gun. 
 

@Goat259 what is the longest you can load and still fit a Tangfolio mag and chamber?

If your only dealing with small amount of bulge brass save the roll sizer expense and pick up a Lee bulge buster set & a cheap single stage press.

@jaydee I have done plunk tests out to 1.135 and still pass. 
 

I have come with a load though. 
 

1.130”

180 Blue Bullets

4.5 grains of N320

170-171 Power Factor 

 

Is this acceptable? I don’t want to wreck my gun.

Well you could try the Redding GRx die, I used it for years before I got my Rollsizer. But since the Rollsizer I haven't had a single round fail to gauge.
