i also hope someone or company builds heavier grain bullets for a .257 caliber,i have another reason i took a long action Remington model 30 express and put a new 7 1/2 twist -257 Roberts- 25 inch barrel on this action. yes i can get 115 gr.bullets to shoot well but i wanna try a better heavier grain bullet that will shoot a hole just cause i like that.my grandkids,wife ,daughter and myself in the future will all be using 257 Roberts, I have plenty 257 Roberts brass new and used ,plus enough rifles too. i have always had a real soft spot for the .257 bullet and the 2 cartridges 257 Weatherby Mags. , 257 Roberts and now for fun this 257 Creedmoor. we all need to ruffle the feathers somehow on these bullet manufactures to make heavier grained and better bullets for the 25 caliber ? here on the fire we do have some talented people who may be able too help us influence bullet manufactures big and small to build/make 25 caliber bullets better and heavier. you do have to say thank you to Black Jack bullets for trying to revive the 25 caliber also.

They need to resurrect the Hunter class of target shooting where 25 cal. is the minimum. That might stir some activity for better bullets.

I understand that Sierra is making the BJ 131 grn. bullet? If true, can`t ask for a much better co. to do that than they. I`m sure the speed at which this bullet sells tops the list for a reason to continue.

One reason why I think Pete is going backwards with testing 115 and 120 grners. I know they will shoot very well in my 10 twist rifles...I want to know how the 131`s shoot in the 8 twist barrels before I go that way.

Unlike the BJ site and company, Pete is not trying to sell the concept, so would like to see him and others continue testing with the 131`s.

yes Sierra is making the 131 gr.B.J.

I fave 2 different cartridges 1 is the 257 Creedmoor,the other is a 257 Roberts both have brand new brux 7 1/2 twist barrels both shoot 115 gr. Nosler B.T. ,Hornady 120 gr. and 110 gr. and Berger 115 gr. bullets both rifles shoot consistence 1/2 -3/4 groups out of all these bullets with both rifles. i still am trying to get some kind of consistency with 131 gr. B.J. bullets.>> i like the concept but these 131 gr. bullets from Sierra /B.J. are not the true answer for me yet ? maybe i got 2 bad boxes of 500 ? but all the other bullets are just hunting bullets and the Berger 115 gr. hunting bullet is the most accurate of them all and cheaper too than B.J. 131 gr.. the machinist who built these rifles for me has built and machined target rifles that have won at the Nationals too, the late Jerry Simonson and this machinist were very close friends in the world of building rifles too. >>as far as a great bullet company Sierra is just ok now days Berger makes much better bullets just go ask the benchrest shooters who do well .

Pete...I quess my point was that no Co. to date, that I know of, has made heavy .25 cal bullets other than Sierra, and they have a pretty good track record of making an accurate bullet.
If Brian Lutz can figgure one out for the .25, I`ll get a 7.5 twist barrel.

Good Luck with your tests.

went to the 200 and 300 yard range yesterday ,had some mirage at 200 yards and way to much mirage at 300 yards. but at 200 yards 115 gr. Berger hunting bullets even with mirage still shot 1 inch 5 shot groups.here in Minnesota ground is so moist yet we get to much mirage yet so these groups may be smaller if it was dry and as the day got warmer the mirage was worst too yesterday.at the end of my day of shooting i shot a 5 shot group with 115 Berger bullets at 100 yards and still shot 1/2 inch group ,it still amazes me how i can just reset the Nightforce scope back to zero and those bullets go right back to center of bulleyes.

>200 yards -5 shot groups<
115 Berger`s - 1 inch
115 Nosler B.T.-1 1/2 inchs " these B.T. bullets have the black coating from Nosler"
131 B.J. - 1 1/2 inchs

been wondering maybe if i use less pressure on the neck,maybe those 131 gr. B.J. bullets would group better ? i am using a Redding bushing die " 6.5 Creedmoor then change bushing to form it to a .257 Creedmoor cartridge " which this bushing was recommended a .282 bushing,i just ordered .283 and a .284. just maybe this simple change will help ?

Pete,
Have you tried any 100’s? I am interested in the cartridge for deer hunting.
What velocities with 100’s and please include barrel length.
Thanks
R



Jack O’C had it figured out in the 60’s !

i should mention this to you my 257 Roberts i built shoots 115 B.T. Noslers and 115 Berger bullets excellent 1/2-3/4 inch all day long with this new 7 1/2 twist,25 inch Brux barrel it is very impressive,if i played more with this 257 Roberts rifle it might even shoot better ? but its a hunting rifle so that`s good enough i am not hunting mice these 5 shot groups are good enough.

Thanks for the info Pete, will keep that in mind. I`ve a new, 300 rnds down it, Pac-Nor chambered for the 250AI on the tube gun. Shoots so damned good I hate to change it. But, I`ve also SA 700, same chambering, that has many,many more down the tube. This one is my hunting rifle too, so that 7.5 twist does not sound that "over stabelization" is an issue with either of the 115grn bullets. Could be a good candidate for a barrel change.
Thanks again.

Sorry didn’t go through everyone’s comments on the thread, but the 257 Roberts, 257 CM and 25 Souper all perform the same. The Souper has been around for decades and fulfills the SA side easily in the .257. .257 bullets do not present the same COAL problems for SAs. The 308 Win family cases will do the same as a CM case when it comes to a .257. If I were to want a .25 Wildcat it would be 25-284. Plenty of 6.5-284 Norma brass available from Norma and Lapua. Would smoke all the other three in a SA. Nothing wrong with the other three, but a 6mm CM would cover the bases well in a SA, would have a tougher time keeping up with the 25-284.

>sorry but my little experiment with a 257 Creedmoor just might becoming to an end not sure yet ? reason is i ordered a new Red Ruger M.C. Precision 6.5 Creedmoor this factory rifle has all the bells and whistles on it from the factory and 6.5 target bullets and hunting bullets are excellent ,have many options and easy too find and buy. besides i have plenty 6.5 target bullets already because i have a 6.5 -284 bat action bench rifle already. so if this Red Ruger rifle outshoots this 257 Creedmoor rifle ,i will either wait for a while for better hopefully .257 bullets or sell the barrel and B.J. bullets too ? there comes a time its better to try something different and/or drink the 6.5 Creedmoor kool-aid ? i am happy with the 257 Roberts Remington 30 express rifle i built that is a keeper and to me a great old rifle that will be handed down in my family, my 257 Weatherby Mag. Ruger #1 will always be my main deer rifle 100 gr. Nosler Partition going 3800 FPS > its my no track`em rifle if and when i squeeze the trigger on a big old Northern Minnesota whitetail buck. >>it still is disappointing that bullet manufactures have left out making different weight and target .257 bullets ,many of us know dang well it would and could be a great size caliber bullet for bench rest competition.

was going to try some 100 grain Nosler Partitions out of my 257 Creedmoor today but its too windy,i did purchase a new Caldwell chronograph it uses phone for velocity of bullets you shoot ,will also store shot groups too,the app. is free when you purchase this chronograph which is kinda neat too.so hopefully either tonite or monday A.M. ?

last week i treated the 257 Creedmoor barrel with DBC just to see if it stays cleaner ? today i shot one 5 shot group after i fired a couple of rounds to dirty the DBC clean barrel . my 5 shot group shot 3085 -3115 fps with 100 grain Nosler partitions group was under 1/2 inch with 4 in same hole .sun was out had a little wind too, this small cartridge shot fast and is accurate with most bullets i have used.would be a great cartridge to be manufactured and also have someone to make better target bullets for a 25 caliber too.

well i don`t give up easy on a rifle,i will try other loads in this 257 Creedmoor, so as a gun dealer i purchased some Hornady .257 117 gr. SST bullets or just a flat base bullet to try in the 257 Creedmoor i have now loaded these bullets and waiting for the wind to quit here in Minnesota. i also reloaded those 5 used Lapua cases that i always shoot 1/2 inch groups with ,i used 131 gr. Black Jack bullets with less RL.17 powder that will be my other experiment those 5 cases that always shoot well with other type/brand bullets. i also purchased a new Ruger precision rifle that is half red and half black that is creo-coated in a 6.5 Creedmoor ,its really just a bolt AR platform type rifle but is very neat looking and comes with all the bells and whistles. i also did clean this new 6.5 Creedmoor barrel and put DBC in this 6.5 barrel takes a few days to dry per instructions.

nice day today sunny and a small breeze only, so i shot the 131 gr. Black Jack bullets with my 5 used Lapua cases that shoot well always, 39 grains of Reloader 17 the group measured 1/2 inch shot at 100 yards. i also shot Hornady 117 gr.SST bullets with Reloader 17 with more powder they shot poorly 1 1/4 inch 5 shot group . i am going to try even lower amount or Reloader 17 and see what happens with both of these 2 bullets.i did not set up my new chronograph either,i probably should have set chronograph up but i was a little lazy today. have a great MEMORIAL Weekend and always thank a soldier !
