Hi guys,

I wonder if any of you can help me out with some load data for a 7x57, I have a ruger no.1 in stutzen version, lovely little rifle

I want to use a 139gr bullet to start with, so if anyone can be of assistance, your help would be very much appreciated.

It seems nowadays that the 139gr and 140gr labels are interchangeable - often the 139gr in 7mm bullets & ammunition actually weigh 140gr.

If you've got the Ruger No. 1 International (RSI) - often called 'Mannlicher' ;) - these came in different incarnations with short or standard length barrels. From memory the earlier ones were 22" in a 9.5" twist, and had a short rather than the (usual) long throat. Which length barrel is yours?

Those I know who own Ruger 7x57s, especially the No.1A, have rifles with pretty long throats, but I would not worry about tuning to that too much.

What kind of powder do you have?
H-414 and W-760 ( same powder ) are very good in the 7x57.
44.0 grains for 2,650 and 48.0 gr for 2,800 fps

---- Some Ruger No.1 loads from friends ----------
145-gr Speer BTSP 46.0 gr IMR-4831 2,625 fps 46,000 CUP 3.065 (inches) 0.75 inch groups
145-gr Speer BTSP 49.0 gr H-4831 2,719 fps 46,000 CUP

150-gr Nosler BT
RL-19 48.0 gr
3.065 inches COAL
One ragged hole ( photo ) from a Ruger No. 1A

140-gr sierra Prohunter or flat base Nosler
48.0 to 50.0 gr H-4350 ( near MAX )
Ruger No.1A
5 holes touching.
50.0 gr load is 2,750 fpt from 22 inch barrel pressure about 50,000 CUP

Ruger 77
Nosler 140-gr Accubond
50-gr H-4350 or 48.0 gr IMR-4350
5 shot groups holes touching in a cluster every time. 4 deer at 200 yards or more

154-gr Hornady
46.0 gr to 47.0 gr IMR-4350, RL-17, or RL-19
3.065 inch OAL

Hornady 139-grain GMX

I'll add my favorite 7x57 load: 140 grain Speer Hot Cor, upper end charge of H4831, Remington 9 1/2 primer.

My most accurate 7x57 load.~Muir
