Skip AI, I have two 25/06 AI's, and have being using this case since 1986.
I have chronographed loads with the 90, 100, 115 and 120 grain bullets. I used the 100 grain bullet for my field shooting for about a decade, and found that powders such as IMR 4831, Re 22, Viht 165, worked well with this bullet.
Recently decided to try the Nosler 115 grain BT in my field loads for something different, and have been getting sub 0.5 moa with this bullet using Hodgdon 1000,(AR 2217 for us in OZ).
My experience is that in a 24 inch barrel, you can obtain around 3,550 - 3600 fps with the 100 grain bullet, and 3275 - 3300 fps with the 115/120 grain bullet.
I love the case, and am looking forward to testing the Wildcat 130 and 142 grain bullets when they arrive in the next few weeks. Regards, Brian.
Thanks for that,
Well Im only a varmint hunter at the moment so I dont really use the 100s and over.
I currently use a 85gn Nosler BT and is very accurate.
I use 60gns of AR2213sc to push it out at about 3600fps (so ive been told).
I have only had it for about 3weeks and havent really looked into makeing it hotter.
What do you think the MAX load is in this cal?
Whats your setups?
Have you used the 85s?
Yeah, I shoot a 25'06 Ackley, have had three, so far. I decided that the 100 grain Nosler Ballistic Tip did everything I needed done, after trying many different powders and bullet combinations, over the years.
I have a load for 110 Bergers and 75 V-Max, but the 100 Noslers are the best all around choice, big game and large predators.
Specifically, in 270 Brass I use 57.0 grains of R-22, a Fed 210Match primer and record a MV of 3650fps from a 28.5" barrel.
SkipAI, There are a variety of different chamber sizes in rifles based on wildcat cases, so it is inadvisable for me or anyone to give you a specific load to use in your rifle.
To expand on the above comment, your load of 60.0 grains of AR 2213sc (H4831sc) with the 85 grain bullet would be a mild load in my rifle. 62.0 grains of AR 2213sc is my maximum load with the 100 grain bullet, so it is reasonable to assume that about 63.5 grains (100% loading density) of the same powder would probably be my maximum with the 85 grain bullet. However, apart from general interest, that is irrelevant as far as your rifle is concerned.
I suggest that first you ascertain what the usable powder capacity of your fireformed cases are. To achieve this randomly select a primed resized case, and then fill it slowly with the AR 2213sc powder until it occupies to the base of the neck. Then empty contents onto powder scale and weigh, and repeat the procedure with at least another 2 cases to get an average.
Now if your current load of 60.0 grains AR2213sc is not near achieving maximum pressure, and your test has revealed that you have another 2 - 3 grains of usable case capacity, then you can gradually increase the load by 0.5 grains at a time, fire, observe the pressure signs, and at the same time closely observe the accuracy trends. Also, I find a chronograph is certainly a valuable aid in working up to maximum pressures. So if you can either access or buy one then I believe you will find it worthwile.
If your accuracy (and velocity if tested) are not up to expectations, and you believe it is a powder problem, then I suggest you try Winchester WXR, as it it very similar in burning rate to AR 2213sc. The majority of gunshops in Australia, only stock ADI and Winchester powders, so your ability to experiment with various powders will be limited.
Although, I have not tested the Nosler 85 grain BT, judging on my results with the 90 grain bullet, and my observations of others results, I believe that you should achieve around 3,700 fps in a 24 inch barrel. Good luck, Brian.
