Kachok,
I have to say that the 25-06 has been my sweetheart caliber for quite a few years. Maybe not as long as some but long enough to have been able to wring out plenty of different loads in order to know what works, and works well. There are not as many weights in this caliber as in some but the ones there are will cover your needs up to and including elk if needed.
This said, perhaps the best of both worlds can be had using the 110gr Nosler Accubond, and/or the 115gr Partition. With either of these you will be able to get your velocities up in the 3100-3200fps range easily and with no major issue regarding pressures. They will both shot flat enough you should easily be able use a duplex retical to precisely place shots out to 400yds.
With my standard version I have been shooting almost the same load for close to 20yrs and haven't seen much it couldn't handle. I used the 115gr Partition loaded over RL-22 for 3150fps out of the factory Remington 24" tube. For whitetail it is simply a non issue when placed in the shoulder region. This particular rifle also shoots the 100gr and 115gr Barnes X, Partition, and the Ballistic Tip all into less than 2" combined at 200yds. The individual groups are equal to the one posted below. I have taken a skunk at 285yds with a head shot using the Barnes, and whacked a yote at just over 350 one morning sitting atop a wobbly tri-pod stand using the Partition. I do admit however I missed the exact spot I was aiming by about an inch, and instead of hitting him right between the eyes I managed to hit just below his left eye. I felt this HAD to be due to the stand wobbling in the breeze however, as I know it couldn't have been me.
I never really liked the BT as it just seemed to be a bit more explosive than I felt was needed on deer, and for a hog was simply like hitting them with a grenade. With the 100gr bullets I found nothing better than IMR-4831, and as mentioned with the heavier ones I used RL-22. There might be better powders for individual rifles, but overall, you will find the majority of accurate loads used by folks will be with these powders and there has to be some reason for that.
I decided a few years back to pass this rifle over to my daughter, since we usually fought over it anyway, and in the process, I picked up a box of the then new 110gr Accubonds. While my bud and I were shooting one afternoon I decided to give them a try and simply swapped 5 of them out for the Partition changing nothing else. We actually had to ride out to the target to see that they all went through the same somewhat enlarged hole at 200yds. Since then she and my grandson have used them to take some nice deer from our property over the past 4-5yrs.
Here is a shot of my grandson's first group past 100yds. He was simply shooting up some old ammo I had sitting around for it to get in some trigger time. I had the target set up at 235yds due to working on a max point blank zero with another rifle.
After he managed to run a few dozen rounds through it, we moved the target out to 250 so I could check the zero on it with the hunting loads. I cleaned it, and fired one fouler and two for group. The wind was bumping along at around 15 or so and gusting up a bit more that day so I didn't bother with adjusting the scope. For the most part I felt it was about as good as I had left it the previous season. This is the 110gr Accubond loaded over the RL-22 load I also use for the 115gr. I have checked the velocity several times and it is consistent at or around the 3250fps mark.
The year I passed that rifle over to the daughter I built my 25-06 AI. I had been wanting one for quite a while and this gave me a good excuse. I found a donor 30-06, ordered a Broughton 5C 28" 1-9 #4 barrel for it and when finished up it was definitely much more rifle than my previous standard version. I went with the faster twist in order to use up some Wildcat 125 and 130gr bullets I had, and had hoped to be able to get some 142gr that I also had, to shoot. The latter however simply can't be pushed fast enough to stabilize. This didn't bother me too much however as the standard 120 through the custom 130's will all shoot as good as the above rifle does out to 300yds.
I managed to find a source who had a bunch of the old Remington 120gr CL's, and purchased a bunch of them simply to use them for FF loads, but after finding out how well they group, I am now using them as my standard bullet. I haven't had this one out as much as I did the other, but I did manage to get this small hog at 275yds with an ear hole shot, resting over the hood of the truck in my back pasture. I was using the 125gr Wildcat,
I then got this ol brute the following weekend in similar fashion but offhand at about 110yds. He hit the ground so fast I actually thought I missed him as he was headed into the brush. This one was using the 120gr Remington.
I had my doubts on how the Remington held up, but when we dressed him out it was plain to see that the 3350fps muzzle velocity wasn't going to be a factor with these bullets. Here is the one I recovered from the hogs above.
There are a few more pics in my 2010 Hunting album at the bottom link under my sig, which show a few more of the hog and the damage done by the CL, as well as a few with the daughter and grandsons deer they got with the standard version with the laminate stock.
I am hopeful that the AI version will serve me as well as the standard version did, and if I were to do anything differently I would stick with the standard 1-10 twist. I believe it would allow a tad more velocity with equal loads and a bit less pressure. This said I simply used the standard load data and worked up incrementally measuring cases, watching primers, and velocities as I went. I did find what the max was with the powders I worked with and also the bullets I had chosen to use before I managed to blow anything apart. I can say this however, the 3350fps with the 120gr is plenty safe in this particular rifle. I have gotten over a dozen loads from the initial 20 cases I picked out of 100I have FF'ed, which have shown no signs of primer pocket looseness. To me that in of it's self is a testament to the particular load I am using.
Good luck with your build, I doubt that once you get it done you will have much if any issue finding a great shooting load. The hard part is deciding on which one to settle on.
