25-06 Ackley Improved

Is there any books that have reloading data for this load? Only place I have found is I can't seem to find much info on this load and it looks really intriguing. Are guys really getting 257 weatherby velocities out of it? Thanks in advance.

I know two guys shooting guns in this caliber (built at the same time with same reamer and barrels) and they are getting just over 3400fps out of a 27" Shilen barrel with a stout load of R-22 , one claims to get 3900 fps with a 75gr V-max bullet. Knowing these two boys I'm sure that they are shooting max loads .

Yes sir, you can find plenty of load data in Sierra Manual #5. I have posted a couple of my loads on also, for speer 87 tnt and 100 grain SMK, under not verified loads. I get 3600 with my 87 grain load, IMR 4350 can go faster too. I think 3900 fps is doable with the 75 grain V-max, I have 10 boxes but they don't shoot good with this particular barrel (1-10, 3 groove). Good luck with this chambering, its been alot of fun. I've added a picture of the this cartridge loaded with the 100gr Sierra Matchking, just for giggles. Here's the link since I cannot post attachments for some reason---

In a standard 25-06 I have gotten 3900fps with 414 and 75gr Vmax.With a115 Berger VLD 3200fps the powder of chioce is VHIT N165. This in a Ruger KM77VT 26" My cases were formed from National Match 30-06.In an improved version these velocity's should be doable with no trouble. I have found the N165 is slower than the loades in the vhit manual indicate.

I was getting 3660 out of a 100 gr NBT in mine. I'll look up the load if you need it.
I just know enough about long range shooting to kno that I dont know sh*t about long range shooting!

I have one built on a Ruger All Weather. 100 grain Partitions top out at 3525 with IMR-4350. I also load 75 grain V-Max's to 3850.

I wouldn't call it 257Wby performance but a solid 150 fps over the parent case. It is worth doing.

My 257Wby in an Accumark runs the same bullets at 3700 and 3950 respectively.

If you have a 26" barrel I would just go ahead and make it a 257Wby. Then your brass is ready made.

Only accurate rifles are interesting.
