Dgutter,
All the advice above is good...While having reloaded for 45 years I must admit I have only been loading the 25-06 for the last three decades....It seems like that I have tried a lot of bullet/powder combos ....Recently having built a couple more 25s has kept me busy looking for that perfect load....
Good hunting bullets for deer size game are all mentioned above... I personally have had good luck with 110 Accubonds, 120 grain Speer SPBTs, 120 Sierra Gameking SPBTs, 117 Hornady SSTs, 117 Hornady SPBTs and some limited success with 115 VLDs.......Nosler Partitions would not shoot for me in any of the three rifles (but maybe I never had the right combo to really even start tuning)....
The VLDs shot great groups (sub moa) out to 500 yards in only two of the three 10 twist rifles (you really have to play with the jump/jam to find the sweet spot)....The Hornady bullets seemed to like IMR 4350 best and are good tough game bullets with the SST being somewhat more accurate as far as groups in my rifles....Hornady groups varied from less than 1/2" to 1" at 100 yards but opened up quicker at longer ranges.....The Speer 120s grouped well in all three using H4831 & H4831sc out to 300 yards...The VLDs shot best behind 54 grains of H4831sc....
Every rifle is a science of its own, so as mentioned above start out low and work your way up.....In my opinion I believe you should try the heavier bullets first to see if your rifle will stabilize them, because the heavier bullets will give you best down range performance on the game.....Right now I am building 2 new rifles both are .260 Remingtons and the load developement starts again....
Good luck with your 25,
Randy
