9mm max OAL

Depending on the bullet you are using longer and it may not chamber. Much depends on the bullet olgive. If I were you I would stick to recomended length for the bullet you are using.

I dont wanna hijack the thread, but thats the exact same confusion I'm having.

I use Frontier 124 grain Plated Lead, and I've No clue how deep to seat the bullet. The sides of the bullet are smooth, no groove to guide me. I've seated them to 1.090. But I dunno, they are not as deep as the OEM stuff I have.
 
One way to determine the maximum length of a cartridge using a particular boolit is as afollows:

1) Remove the barrel from the gun

2) Drop a bullet into the chamber

3) Take your calipers and measure the depth from the base of the boollit flush to the base of the barrel.

4) Add the length of the boolit to the measurement you just took and you have the maximum length of that boolit in your gun. I would back off a thousand or so to ensure my booloits were not hitting the rifling.

If my instuctions are not clear send me a PM with your phone number and I'll call you after Boxing Day.

Merry Christmas

If you seat too long, the rounds won't fit in your mag. Too short with max loads and you can create unsafe pressures. The OAL's suggested in your reloading manual should be followed for the given bullet weight and you won't have a problem.
I find the 147g winchester JHP's have to be seated shorter then recommended as they won't fit in my mags. Reduce max loads by at least 5% if you ever run into this situation.

Might fit in you rmag and not chamber in your gun - olgive could catch rifling.

Problem with some of these plated bullets is data does nto always cover the bullet in question. Sticking with manuals whrere possible is the best method when you can.

I should have added I have some plated 124 gr bullets from a company out of Quebec and loaded them with an OAL of 1.15. They chambered and shot well.

Jacketed/plated data would be the same. As far as not chambering because of being too long, that's what the MAX oal is listed for. Pistols have long throats as an added safety to that anyway.
 
Certainly would if the bullet shape and length are the same. Jacketed can be driven faster than plated, depending on the manufacturer. some fellows report problems when plated are driven to fast.

For compatibility with different guns/mags I keep the OAL down to 1.100 for all my 9mm luger. I have loaded about 100,000 rds with no problems.

I just realized your using the exact same bullit as me too... 124 Frontier RN full jacket.

In my Glock 17 these work well with 1.090 OAL

I just grabbed 10 115g frontier bullets out of the box and weighed them for ####s and giggles. No 2 weighed the same and the spread was 110.7g to 119.4g.......
I think I'm going to use 124g data to play it safe.......:)
 
The type of gun the ammo is to be used in will have some bearing on OAL.

For example, the 1911 types have a magazine which permits a longer length than the BHP types, so ammo for the former can be loaded using more powder and yet maintain acceptable pressure levels if seated out for a longer OAL.

This the same principal which IPSC shooters apply to 40's built on a 1911, S*I or PARA frame. Ammo used in these applications will not chamber in a Beretta for example

In any application go for the longest OAL which will, fit the mag, feed and chamber. OAL under this criteria will vary with bullet type and ogive.
