Mark, watching your primer for signs of flattening worked for me. Again In modern BOLT action rifles.

Hi,

As barbaric as it may sound, this has been my procedure ever since I started handloading in the mid to late 1970s; and I have yet to blowup either a rifle or pistol by using it.

It is amazing how much one can tell just by reading the casing and primer. With hotter rifle loads, I might measure case expansion at the base, comparing it to a factory fired casing.

Usually, with military type rifle loads, I have gotten my very best groups at or near maximum loads (6.5x55 Mauser and 7.62x54R Mosin are good examples).

Your thoughts and comments?

Respectfully,

Sieger

For both .30 Luger and .30 Mauser/Tokarev, I use a couple of bullets. The 90 grain .309" Hornady XTP HP works well with 5.0 grains of CFE Pistol Powder in either cartridge. The Luger is a much stronger action than the Mauser so I keep my Mauser loads as mild as possible while reliably functioning the action.

Doubs,

In your post quoted above, what depths did you seat the bullet to? I also use the Hornady 309 90gr XTP in my 7.65 Lugers, and I seat it to 1.148" COL. For a round nose bullet I might try to get closer to 1.165" but a hollow point is shorter, so I'm thinking 1.148 is about right for that shoulder. It feeds and shoots fine using 4.8 gr Alliant Power Pistol (mild to medium). Would be interested in your COL and your assessment of how CFE Pistol compares.

I have not used the Hornady bullet in my 7.63 Mauser loads. Wasn't sure it would be okay. I use the Sierra 85gr 308 RN soft point seated to 1.370" over 5.1gr of Power Pistol (mild load). Would like to compare your load (COL, recoil) with mine if possible.

Thanks very much for your very helpful info on new versus old pistol chambers.

Glen, I've seated the 90 grain Hornady XTP bullet for an OAL of 1.56". It works well in my .30 Lugers. CFE Pistol Powder burns clean and seems to have the proper impulse to work the Luger action. I also use it in my 9mm Lugers.

Whatever OAL you use, two things are important. First the cartridge must feed through the magazine. I've had magazines where the bullet would hang up on the notch that secures the magazine in the pistol. The OAL was too short and seating the bullet out a little more cured that problem. The second issue is the chamber itself. I have an old barrel taken off of a Portuguese 1906 Luger - their M/909 - and I drop every cartridge I load into it's chamber. If they seat properly, I have no problems in my Lugers.

For my more modern pistols such as my Benelli B-80 and Browning Hi-Power, I have to seat the bullets deeper as they have chambers with short leads that will not chamber my Luger loads.

If your Mauser loads using 85 grain bullets work OK then stick with them as the bullet weight is very close to the original 86 grain Mauser bullet. If you try 90 grain bullets, reduce your powder load some.
