6.5 Creedmoor or 25-06 for Deer

[MudRunner2005]

Phorwath, or just go ahead and max out case capacity, throw on a 26" 8" twist barrel and chamber it for 6.5 Sherman and push those new Berger 155's over 3,100 FPS.

Like I stated in the very first post, the only thing hindering the .25 calibers is the lack of heavy-for-caliber jacketed lead hunting bullets in the 130-140 grain range. If the industry brought the .25 calibers up to modern standards (like everything else), the .264 would be crapping itself how close the .25-06 AI and .257 Wby would be to the .264 WinMag's capabilities.

I'd also love to see a .257 Sherman pushing a Berger 140 Elite Hunter over 3,200 FPS MV... Hint, hint Rich! Get Berger making those bullets so you can cut a reamer and some dies.

Rebated boat tails do not work well. Tried them.

I've concluded the rebated boat tail bullet design provides no BC, or accuracy/precision advantage. Those benefits are imaginary - unreal.

lookin at the comparison at 500 yards it looks like the 257 will have quite a bit of elevation advantage and minimal difference in windage I would like to see the comparison done at 500 to 600 max where the usable range is going to be at hunting

I own a 25RUM, but it's a 10-twist. The 10 twist is pathetic with the RUM case capacity. I need to replace that barrel, and I'm open to other calibers & cartridges. So I read thru this thread with much interest, yet an objective mind-set.

The diameter difference is only 0.007". I don't expect huge differences in terminal performance in cartridges of similar volumetric capacity. Two cartridges specified in this thread, so capacity is now a known. 25-06 prevails in that criterion. Yet the .257 bullet offerings are sadly lacking.

Straightforward solution for a reloader is 6.5-06. Neck the 25-06 up to .264. I know,... That's cheating!

Impose the factory ammo and factory rifle limitation between the two specified options, and the better selection seems to be the 6.5.

Remove any and all cartridge limitations and include all available barrel twist rates (my situation), and 6.5 seems advantageous based on the abundant bullet offerings available in 6.5.

Cheating a second time, maybe I should go 6.5RUM with the appropriate twist rate to handle arrow-length bullets!

This could transition into a complete and total Thread hi-jack, so I'll end this post now.

6.5 RUM with some wc 872, sorry for gettin in on a jack but I like!

There is no such thing as "inherent accuracy". There is only accuracy and inaccuracy. And it has more to do with the rifle and barrel, than the caliber & cartridge that it's chambered for. There are, however, some cartridges/calibers that are easier to get shooting than others because the cartridge design is less picky or was better designed than something else, but as far as "inherent accuracy", there is no such thing.

Inherent accuracy is accuracy by burn parameters of powder and is inclusive of cartridge case design.

I don't have the background on a creed but theres a lot of info here..been loading for 260 Remington for years..nice caliber..tough to beat for bullet choices... I have a Remington mountain rifle in 2506(noodle barrel)it is a shooter....but it does lack in bullet weights....
Have the the same rifle in a rechambered 280ai....it will shoot also...
For better bullet selections I would go 280....and there just happens to be one for sell on the site right now...if I had the funds it would be coming this way already...I find that rifle very nice for packing and shooting...some people float the barrels..but I did some background and bedding the front of the stocks made a huge difference.....
So for bullet choices .257 is lacking...

I have both a 260 Rem. and a 6.5 Creedmoor, I get 50+ fps out of the Creedmoor using RL-26 using 135 grain JLK's using less powder weight.

I know what people are referring to, but there is no such thing. There are only better designs equalling to more burn efficiency than others. No cartridge is "inherently accurate", as accuracy has to do with the barrel and action quality/precision.

I understand barrels, they are all different, the 21st Century cartridge cases are more accurate than 20th century cartridge design. I rest my case with the 6mm PPC.

PPC , (sic)

Absolutely, but it's not "inherent accuracy", that's just a misnomer. It's just better cartridge design thanks to modern technology and scientific advancement.

I'll say this, both the 6.5 creed and 25/06 need charts for shots over 500 yards and in wind! Which chart do you wanna read!

I know bullets drop, I know accuracy is in the horizontal. We all know vertical. B.C. decides accuracy, not necessarily 150 fps

I'm looking to build a custom deer/antelope hunting rifle. I can't decide which caliber I want to go with and I'm looking for suggestions. I will be reloading for ammo. I want a lightweight rifle so I'm trying to keep the barrel length in check. Thanks for the help

You could build a short action 7" twist 25 caliber then neck a Creedmoor down to a 25.

I've concluded the rebated boat tail bullet design provides no BC, or acurracy/precision advantage. Those benefits are imaginary - unreal.

The rebated boat tail would give better barrel life as it spreads a flame against a common force instead of an angular burn. The rebated boat tail is the saving of barrels between a common boat tail bullet and a flat bullet.

Or take a 243 rem case necked up. Oh wait, done long befor the creed came along
