New Ruger No. 1 .25-'06

Did load development for rhe 25-'06. A 115 grain Nosler BT and 49.5 grains of IMR4350 yields a five shot group of .56" - adequate, at least. No chrono work yet but I am pretty confident it will do what's needed.
Yeah I would say a half inch 5 shot group is adequate! I used that same bullet in a .257 Roberts to dump a nice Montana lope some years ago.
I dont remember the load but it clocked at just over 2900 fps.
 
Sounds like a winner. What did you do to get the scope positioned correctly? No. 1’s are pretty challenging from that POV.

Yes they are. I had originally planned on a S&B Summit (2.5-10X 40) but it did not have enough eye relief. I asked John McLaughlin, who did the metal work, to move the front sight block about 1/2" to the rear, which he did. Still not quite enough, so I went with the Leupold VX3HD 3.5-10X for a bit more eye relief. I'll put the S&B on either the 280AI or the 308 Norma Magnum that are being built now.

I did find that my scope needed help to print low enough on the target, so I shimmed the front ring .004" and I may go another .004" to get some 'slack' to sight for 275 yards.

Fun project. Pete Mazur did the metal finishing and it is very nice. Here's a recent 5 shot group... still a bit of work to do.

Hi Roklok
I read your post on Caprivi. Congratulations.
I plan to hunt there for buff in 2026 oct.
How was the land, very dry ? But à lot of buffs ?
Thank you / merci

Chopped up the whole thing as I kept hitting the 240 character limit...
Found out the trigger word in the end... It was muzzle or velocity. dropped them and it posted.:)

2,822fps, ES 8.2
This compares favorably to 7 Rem Mag. with less powder & recoil.

I know that this thread is more than a year old but as a new member I thought I would pass along my .280AI loading.
I am shooting F Open long range rather than hunting but here is what is working for me and I have managed a 198.14 at 800 meters.
That is for 20 shots. The 14 are X's which is a 5" circle.
