I have a Belgium Mauser 25-06 sold by Flaigs. It has a 26" Douglass barrel.
I am currently shooting 75 grain hollow points with I think its 53 grains of IMR 4350. This load shoots pretty good in the rifle and was one of the recommended recipes of the previous owner. I settled on this after lots of testing of other combos. Some would shoot really good, but weren't as consistent.
I have tried several things in this rifle. IMR 4831 and 4350 and varget. I've tried nosler 85's, sierra 87 and 100 gr matchkings. Nothing has really impressed me and most loads are about 1 moa at 100 yards. My current load shoots a little better than 1/2 MOA, but is tough in the wind. I have been contemplating messing around with the 100 grain matchkings again and also trying some 115 grain bergers. I want to push these as fast as possible, assuming that is where the accuracy is. I will be looking for 1/2" groups at 100 yards.
Can anyone make a recommendation as to what powder to try? I have been flopping between Alliant Reloder 22 and RE25. I would also like to try the New RE 17 under my current 75's, but would rather focus on a longer range load. I will be using this set up for groundhogs only and most shots will be between 200 and 300 yards, but there is opportunity for some 5-600 yard shooting. I just want a good wind bucking load that is pretty flat. That is why I am leaning toward the 100 gr SMK and I seen loads on Reloadernest.com using Reloader 25 that were impressive for a regular 25-06. They are getting nearly 3400 fps.
I had great accuracy outta the 100gn NBT with 57gn of RL22 and CCI BR2's...OAL was 3.280". The Barnes 100gn TSX actually shot better with 55.5gn of RL22 and 9.5M. Both loads are within pressure limits and sub 1/2".
I tried the 115gn Berger and my best accuracy was at 3044fps (.390") using 51.0gn of RL22 and 9.5M, OAL:2.7730"...all these loads were shot in a Sendero SF .25-06. Hope this helps..JohnnyK.
Big – the 25-06 likes the slower burning powders ie RE-22/RL-22, H4831, Viht N-165, IMR-7828, Retumbo, you are on the right track. You can check any of the powder manufr’s sites, they will usually give you load data,such as Hodgdon, Nosler, Alliant, OR, you can get a reloading manual , Sierra 5th Ed., Nosler , etc, etc. PS. 1/2” aint nuthin to sneaze at..
..alos, if your barrel is newer, sometimes they dont start shootin until after a few hundred rounds or so. Mine didnt start shooting real well until about the 400 mark. Also, if you take the same load you were shootin 1 moa at 100 and move further out and practice you may find it shoots great. (another ps. I would personally move to the heavier bullets, 117 SGK / 115 NBT, better ballistics). Good luck.
