[QUOTE="brianwinzor, post: 61306, member: 1067"] nomosendero, As ususal I agree with Fifty's comments, and if you are getting those velocities then stick with the 25/06, as I am only getting those velocities in the newer and second of my 25/06 AI rifles. I currently own two 25/06 AI, rifles, and each was a standard 25/06 for about 200 shots before having the barrel set back and rechambered to the 25/06 AI, and both have 24 inch barrels. Typically I have found that in a 24 inch barrel a 25/06 AI will get between 3550 - 3600 fps with the 100 grain bullet, and 3250 and 3300 with the 115 - 120 grain bullets. You probably could add another 50 fps to those figures if using a 26 inch barrel. Like Fifty, I would also add a note of caution about your pressures and the case life. Initially in my rifle 1, when working up loads in the 25/06, I achieved 3418 fps with the 100 grain bullet, and 3163 fps with the 120 grain bullet, found that neither was sustainable as primer pockets loosend within 3 or 4 shots. So I dropped the loads by 1 grain, and settled on velocities of around 3325 -3350 fps with the 100 grain bullet, and 3075 - 3100 with the 120 grain bullet, and found that cases now lasted 6 - 10 shots. Similarly in the same rifle in 25/06 AI when working up loads, intially I settled on using 61.0 grains of IMR 4831 with the Nosler 100 grain BT, and was consistently geting about 3650 - 3675 fps (3733 on 1 day) with excellent accuracy. However, and probably not surprisingly primer pockets opened up after 3 -4 shots, so I dropped the loads back 1.0 grain (60.0) and found that I was now getting 3,550 - 3575 fps, with much improved case life. Similarly when using the Nosler 120 grain SPBT, initially I was getting 3375 - 3400 fps and acceptable accuracy, but again primer pockets loosened and so I dropped back by 1 grain and to velocities of around 3300 fps and much improved case life. Eighteen years later when working up loads in rifle 2, I have found that maximum load for 100 grain bullet produced 3325 fps in the 25/06 and 3550 in the 25/06 AI. I did not test the 115 - 120 grain bullets as a 25/06 in this rifle, but 63.5 - 64.0 grains (100% loading density) of H1000 or Viht N170 will produce with excellent accuracy (sub 0.5moa) between 3250 and 3300 fps depending on the temperature. Good luck with your 25/06, and just closely monitor the pressures and case life. Brian. [/QUOTE]
