I am going to be reloading .308 with 147 gr. FMJBT and am having trouble finding reliable data on powder charge. I will be using Accurate 2460 as of now but may change powders if this does not work out.

The problem is all the reloading data I can find is for 150 gr. and not 147 gr. My thought is to use the data for 150 but cut it by 1 gr. to start with sense i will be shooting a little lighter bullet. Example, Accurate says the 2460 powder can be loaded from 40.5 gr.'s to 45 gr.'s for a 150 gr. bullet. I will start in the middle but will drop 1 gr of powder. Is this OK? Or does anyone have good reloading data for the 147 gr bullet using Accurate 2460 powder?

Opaww, I found a load for a 7.62X54R using a 147 gr. FMJBT It calls for 42.1 Extruded, (ft/s) 2760, Std. Dev. (ft/s) 9.5, ME (ft/lbs) 2487

The case is steel, Primmer Berdan, COL 3.016 The author of this receipt rated it as GOOD

Its sound as if you are real close on the charge weight. If you need the web site I went to, let me know. Shoot Straight, Stay Safe, Hunter Joe

Opaww That is a rimmed cartridge and will more than likely be loaded to a lower pressure than the 308. DO NOT USE 7.62X54R reloading data for a 308. Totally different cartridges there. Me personally I would call Sierra or Hornady and see what they have to say about loading them.

Now I was using 135gr SMK in my 308 and because the bullet is so new I didn't have any data for it. They said to use 150gr loadings for it. So I am sure if you use the 150-155 gr loadings in the manual and stay in the middle or do a ladder test and pay attention to pressure signs. You should be ok. No need to reduce just start in the middle.
Don't expect to see much accuracy in these bullets. Bulk manufactured and bulk loaded on worn out machines. Remember these were made for machine guns so accuracy was not important.

I am not going to use the 7.62x54r but the site gave me some good info on reloading other things. I will be using the Sierra and Hornady manuals and will be loading based on the 150 gr. .308. I am going to start with middle of the powder charge and work my way up but not to full load.

Mostly these will be shot in the Cetme and I will be reloading 168 gr. HPBT match kings for target in the Howa

For the HOwa look at RL-15 or VV N540.

You are familiar with the peculiarities of the delayed roller locking system, Right?
DO NOT USE .308 ammo in a CETME. I use .308 brass but my load is reduced about 2 grains under max. Near max loads will almost guarantee a case separation.
