was able to shoot yesterday in afternoon here is what happened. 2 shots with the 25 Creedmoor so rifle was fouled then let it cool down. when cooled down shot the 7 matched cases 5 shot in 1/4 inch group the other 2 shot with 3/4 inch i have the 5 marked to try again another day ,i used 40 grains of RL. 17 131 Black Jack bullets. i also shot my new Brux Barrel 257 Roberts ,i loaded 10 new cases with 40 grs. RL. 17 and a Nosler 100 gr. B.T. took 7 shots to find the middle of the bulleye at 100 yards. i then shot a 3 shot group with last 3 and to my surprise first 2 went in the center of the bulleye 3rd shot was 5/8 inch away from the first 2 that were almost in same hole,so now i am wondering ? is it the Nosler bullets ? the cartridge case ? or just barrel is better ? i used cheaper rest and bag when i shot this old hunting rifle and a old 3-10 leupold scope ? sometimes what should shoot well is just ok and the huntin rifles shoot better ? >The next time i shoot the 25 Creedmoor the barrel will still be dirty from the last 9 shots ,maybe it will shoot better dirty some barrels do ? i have now shot a total of 75 bullets thru that barrel all together.

i was able to shoot a few more 5 shot groups using Reloader 17 ,shot 2 - 5 shot groups with the Black Jack bullets with a dirty barrel both groups were poor 3/4 inch, so i tried some Nosler B.T. 115 grain,with same dirty barrel and RL.17 powder load 1 group was 1/2 inch, 2nd group was 5/8 group but 4 were in the same hole. now i wonder ? are the Black Jack bullets better only for 400 yards or longer distances ? i am more impressed with the Nosler B.T. 115 grain now ,so when i have more time will try Nosler B.T. again.

Pete, are you undoing what you`re trying to do with the fast twist Creed by using the 117 BT? I`ve used that bullet in my 250AI for a long time, always with good results. Unless the Creed is providing very high Velocities, I`m still very interested in your findings with the 131 Black Jacks.
BTB, have you chronied those bullets? The BJ?

i tried the 115 B.T. just to see how accurate they are and they proved they are accurate at 100 yards in the 25 Creedmoor.i have been busy with my grandkids lately so that kinda has set me back a little. but once it gets cooler and quits raining so much here in Minnesota i plan on doing some 200 and 300 yard tests with the 131 gr. Black Jack bullets i think maybe these long bullets may shoot better at longer distances but not sure yet ? and no have not used a chronograph yet it rains to much this year when i am out shooting.

shot some 100 yard groups this mourning at my range ,the Nosler B.T. still shoot well in this rifle. i also started shooting 131 gr. Black Jack bullets again these bullets shoot ok a 100 yards some 1/2 groups some 3/4 groups with 42 gr. RL. 17. i plan on just loading 131 gr. Black Jack bullets with 42 gr. RL. 17 and trying 200 and 300 yards next week at another range. i kinda feel these bullets will shoot better or stabilize better at 200 yards and farther my 257 Weatherby Mag. does shoot better at 150 yards and farther too.

So do I, but it's built on a short action, 250AI. Ackley was a smart dude.

its hunting season for me so the 25 Creedmoor gets put on the back burner. the reason i built a 25 Creedmoor is i can buy much better brass > Lapua brass. i do agree 250 Savage case is not much difference but that brass and or brass for my 257 Roberts rifles have the same problem > poorer manufactured brass and no - one makes brass as good as Lapua with consistency for accuracy.

what could a 25 creedmoor potentially do that a 257 roberts could not do better?
look closely at both case dimensions


Fit in a short action magazine with VLD type bullets while reaching the lands and not excessively intruding in powder space. Same with any of the Creedmoor cartridges vs x57 cartridges.

A somethingx57 in a short magazine is definitely not ideal. A medium or long action is a a game changer for the x57s with vlds.

i built my 257 Roberts in a long action old Remington 30 express and it shoots lights out with Nosler 115 B.T. bullets

257 Creedmoor is a new Savage target short action and shoots Nosler 115 gr B.T. bullets great but so far the 131gr. Black Jack bullets at 100 yards i have not got them to shoot consistent yet ,i have tried 3 powders so far including the powder Black Jack recommended . maybe i got a poor batch of bullets ?i plan on doing more testing when its warmer at farther distances.

as of right now i am very impressed with both rifles with 115gr.Nosler B.T. bullets.

Agree. My 7x57 was in a LA, my 257R is in a long action...

If one really wanted a quarter bore in a SA, I think the 257 CM would make sense.

That's as good a reason as any, and better than most, for a new rifle. I'm a dedicated .25 calibre fan and would buy a .25 Creedmoor if they were released by a manufacturer.

i just cried ,Pete when I read you disassembled a Remington 30 Express.. even for a Roberts barrel on it..

you aren't talking a Remington 30S chambered in 30 Remington Are ya?

That rifle and a Model 54 in 30/30 are my two holy grails on rifles on my wish list in life...

I mean a Roberts is a great choice. for a rebarrel...but...

kinda like seeing a vintage 68 Z/28, sitting rolled in a ditch, that was put there by some 16yr old like David Hogg, when grandpa gave it to him for his first car...life ain't fair some days...

my Remington 30s express is very nice ,before i owned this 30 express the caliber was a 25 and rifle had been rebarreled to a 270 WIN. with a Hart 20 inch barrel. i rebarreled this rifle to a 257 Roberts 25 inch Brux barrel and does it shoot well .this 30 express is the nicest i have ever seen but since the barrel had been change i just thought why not make it a 25 caliber again so i decided 257 Roberts had some great old history. this rifle will remain in my family cause it will be one of my grandkids rifle. i have been loading alot of 257 Roberts ammo for the grandkids future,i own 6 - 257 Roberts rifles to give to them.

when you talk Z28 that was a heck of car, personally i would rather buy just a new Z28 V8 super charge Camaro that is a hell of car . it was not to long ago a youngman coming down from Duluth with his new Camaro on the 35 W got clocked going 179 MPH and was arrested ,judge threw the book at him i was told.

its been cold and nasty where i live ,i do have a heated shooting house but i do get mirage when its cold . today i shot one 5 shot group with the 25 Creedmoor i used H4831 s.c.with the 131 gr. Black Jack bullets ,i did have mirage kinda bad but manage a 1/2 inch group so maybe that `s the magic powder ? will try H4831 s.c. some more when its nicer outside , maybe this slower powder will help ?

These look interesting, but the 1-7 twist requirement will limit the use. Dang I went 1-9 on my 25-06 should have gone faster. https://hammerbullets.com/product/257-cal-128g-hammer-hunter/

today its 30 degrees and still, but had a little mirage out of my warm heated shooting house,but the 25 Creedmoor shot consistent 5 shot groups using Reloader 26 i shot 3 - 5 shot groups at 100 yards first group was 1/2- last two 5 shot groups were 7/16 ,i used 131 gr, Black Jack bullets. i also see just a little key hole in the target paper telling me maybe at 150 yards just might be perfect holes then ? next i gotta try those Nosler B.T. 115 gr. with this Reloader 26 ? i do think the 115 gr,Nosler B.T. bullets may shoot better groups with this rifle.

today/Sunday i shot 3 - 5shot groups with new 115 GR. Nosler B.T. using Reloader 26 had some wind 15 mph 30 degrees again,2 - 5 groups were 1 inch, 1 group 1 1/4 inch this bullet does not like Reloader 26 and today i am cleaning the rifle finally with wipe-out,maybe its time for a clean barrel ? then i will shoot some more groups with the 131 gr. Black Jack bullets and Reloader 26 later this week,now that i found a powder that is consistent with these Black Jack bullets.
