OT Load data help. Speer Vol. 4 reloading manual 25 Souper (25-308).

[Stephen Grant]

Hi All,

I've seen a reference from Rock Raahab that way back in the day, the folks at Speer worked up data for the 25 Souper (25-308) in their Vol. 4 reloading manual (around page 67 if I remember correctly).

At any rate, I was hoping that someone may have this vol. in their load data library.

If it would be possible to scan and email a copy, please PM me and I’ll provide an address.

Thank you

Stephen

Hey you know the drill----USE CAUTION

[rflshtr]

I have the #1 and # 4 Speer manuals and both have the 25 Souper or 25-308 included but not any 75 grain bullets. My manuals only show 60,87,100 and 120 grain bullets. Powders are 4831, 4350,4320,4895,4064,3031, and 4198.
For 100 grain bullets, mv range is 2700-3150 depending on powder and charge.

I'll have to look for a old copy of that # 4 Speer manual at the next gunshow.

Thanks for the help.
