Re: Can you make a .25-06 AI perform like a .257 Wby ???

3,600 is more like a 100gr. speed in a 257Wea, although I know some do a little more than that, I believe 115gr. fact. loads in a 257 run about 3,400. Point being, way too fast for a 25-06AI. I do well to get 3325-3350 in my Sendero AI. I look at the 25-06AI with a 26" tube to be about half way between the 25-06 & Wea., which is the appeal to me. I have better brass & less powder & at 100-125fps under the Wea, the small additional speed was not worth it to me. In short, think of the AI as being close, but not quite there.

Re: Can you make a .25-06 AI perform like a .257 Wby ???

I had a 257Wby build used a 1/9 twist Shilen barrel with 115grTSX using 4gr under max load of IMR-7828 velocity was pretty close to 3500fps it didn't have the Wby freebore.

I would think with the right barrel/bullet maybe 1/9 twist 26 to 28" long pretty close to 3400fps with 110/120gr bullets for the 25-06AI and I want it throated for the heavier bullets. If you look at some of Nosler data for the 25-06 with 115gr bullets got 3 loads over 3100fps and 6 loads over 3000fps and Hodgdon has 3 loads over 3100fps with 117gr bullets. Most of my Ackley chambered rifles give me over 200fps gain don't get me wrong that I chase velocity I load for accruracy first velocity just follows that.

Re: Can you make a .25-06 AI perform like a .257 Wby ???

I agree the 3600 is extremely fast for the 25-06AI. I tried several different powders and was unimpressed with the performance. Tried IMR7828SSC and saw immediate improvement. Worked through different weights and backed off when I experienced some signs of pressure i.e. sticky bolt and slight flattening primers. The load I settled showed no signs of excess pressure and was acceptably accurate (load development continues); although from what I read Ackley rounds seem to manifest pressure in different ways. I'm anxious to chrono the load because when working at ranges from 100 yds to 500 yds the data indicates right around 3600 fps; yeah I was suprised myself. Only the chronograph will tell the truth in the end.

I believe it was JMason that turned me on to seating the Accubonds 20 thousands off the lands, it really did the trick in my rifle.

Re: Can you make a .25-06 AI perform like a .257 Wby ???

It will be interesting to see your results Crane. So far I have been impressed with the Berger bullet I'm using but felt that Retumbo was not the right powder nor did it give me the performance I thought I was looking for. That 3600 FPS I have to admit scared the be doddle out of me when I read it. I'm not really looking to outperform the .257 Wby just looking to be someplace between the .25-06 and the .257 Wby with good case life and accuracy.
Only way I could think of to see what everyone thought about this loading was to post up the question and see where it went. Glad you got interested enough to post your experience with the IMR 7828SSC as I have none with that powder. Did go check the availability of it and found both IMR 7828 and IMR7828SSC in stock.

Re: Can you make a .25-06 AI perform like a .257 Wby ???

I really wanted to try the Berger bullets but the availability in my area was nil, plus I really like Accubonds. Hard as I tried I couldn't get H-1000 to shoot worth a darn with Accubonds. I went all through the spectrum of weights and distances to the lands. I've heard Retumbo mentioned quite a bit and figured H-1000 was quite close. I just happened to have a little over eight pounds of H-1000 I use for my Edge and was hoping it would work out.

I had an interesting conversation with Shawn Carlock about H-1000 the other day concerning my Edge. I was telling him I couldn't get up to the recommended loading of 93 grains with the 300 grain Matchking without pressure signs. He informed me that he has had to back off a grain or two himself and believes H-1000 has gotten faster over the last eighteen months or so. I was wondering if anyone else has noticed this phenomenon. I'm glad I have so much because it would be a pain to start load development over when I have to buy more.

Re: Can you make a .25-06 AI perform like a .257 Wby ???

I think that the .338 Edge is possibly going to be my next build and the only thing that has stopped me so far is the fact that I have a really great shooting .300 RUM that loves the 200 grain Accubond bullet. That gun shoots too good to change it till the barrel is gone. Its also a dead ringer twin to my .25-06AI both built at the same time. Biggest stop to the .338 Edge for me is need. Right now with the RUM I don't need any more range.
So far as Berger bullets go in the .25 though it loves them. Don't care that much where you seat them either although a change in powder might change that. Did well on the 110 Accubonds also but I just did not get all that impressed with it. Probably should of stayed with it but kept searching for that perfect bullet/load combination. If IMR7828SSC can get me anywhere over 3400 with the Berger though I think I will call it good and call off the search.
