CFE for 9mm Major

Recommended Posts

OK I am looking for Real world experience with Hodgdon CFE Pistol for use with 9mm Major loads for Open Pistols.

I am looking for actual Data in the following fields.

Pistol used
Barrel Length
Comp used
Poppel Holes Y/N
Powder Throw
Projectile Weight
Projectile Profile
Jacketed or Plated or coated

OAL
Chrono Data


I am Starting to work on this myself and will build my own data set but this this where I plan on starting.

Pistol used; STI TruBore
Barrel Length; 5in
Comp used ; STI TruBore
Poppel Holes; N
Powder Throw; Starting point based on Attached data from Hodgdon's web page. 6gn to 7.2gn
Projectile Weight ; 124
Projectile Profile; HBFP
Jacketed or Plated or coated; Heavy Plate Berrys

OAL; 1.150-1.160
Chrono Data;

So thinking that the test data used by Hodgdon is a 4in non-comped pistol I think Starting at 6gn I should be someplace in the 1370-1400 FPS with the intent to get and keep the FPS around 1450.

And then again to repeat when I get my New Limcat Razorcat.

So I have read this article, and I find it lacking in detail, and writer was not using a open pistol, while I found it as a good source for base line info it does not provide key info for the loading of 9mm major for actual open pistols.

Projectile Profile; HBFP
Jacketed or Plated or coated; Heavy Plate Berrys

Felt good in the pistol, going to knock it up to 7.2 and 7.4 and retest.

Also thinking I will shorten the OAL to 1.150 to build a little more pressure.
