View attachment 225129View attachment 225130View attachment 225131Finally got my 25cm barrel. Got everything tightened down and ready to go. Shot twice last night to function test, make case gauges with, and see where my scope is at. I'll fine tune as I shoot my pressure test loads. Preferred barrel blanks, 20" 1:7 twist with .150 freebore for the extra heavy 25 cal bullets. Alpha srp brass. H4350. Fed match 205 primers. Tikka action, trijicon credo scope. I know a few have been interested and I'll try to keep this thread updated as I move along.
 
Shot a ladder test. Little slower than I planned, but I'm just going by what I can find online. Was hoping to be on the 28-2900 range. I didn't hit pressure so may creep up. 40.5-43 grains in half grain increments, with the first shot of 40.5 being 6" low, and no chrony reading. Same POA and got a .75" group. Not bad.

I really thought I'd be in the 28-2900 range at 41.5. Thought I'd read guys having success there. Initial results being slower, I jumped to 42grains. Not a bad start, but I'll creep up and see what groups look like.

One thing I need to keep in mind is I'm using a 20" barrel. I'll not get the most velocity.
 
I have found that the H4350 powder is not one of the faster powders. I think you will be able to get the velocity up to what you were hoping for. I am getting more than 2600 in a 20" 6.5 CM.

That's good info to know. I've thought about trying one of the 6.5 match or staball powders along with the h4350. I've got test load up to 45 grains, but that case is full.

Im not knocking, but WHY? What on Gods green Earth can a "25 creedmoor" do that a 25/06 hasnt been doing for decades?
 
Shoot long slick bullets from a short action with less powder

Hes gonna end up about 8 or 9 grains less than my pet 25/06 load when its all said and done and the jury is still out on if he will break 3000fps or not, so again I ask WHY?

I guess because he can


Your 25-06 shoots 134's at 3k?


That's impressive, what the load?

I'm just shy of 3100 with 110s in my 25-06. Burning around 60 grains of powder. I'll be 45 grains or less, pushing a 134 around 2850, in a short action.

Read above ^. At the time, a 120 was as heavy as could be found in .25 cal. A 117 gr Sierra SBT, 52gr of IMR 4831 and a Fed 215 would give groups you carried around in your wallet.
Like I said, Im not knocking, just asking what the gain is over a 25/06.

25-06 with 117 Sierra at 3050 and the 25cm with a 134 at 2850

Drops basically the same to 600, drifts less, carries more energy with 15grs less powder and 200fps less velocity

The short action part is about as important to me as the difference between a navel orange and a tangelo. Lets suppose it ends up being 10 gr less powder than a 25/06. So for every 6 shots you gain a shot. Ok, but powder isnt THAT scarce yet.
Which brings me to my next hypothetical question: what will a 25/06 do with those latest, greatest 134gr pills? Could I not go to a slightly slower powder and equal or better the creedmoor ballistics? In the end, I think it all boils down to short action vs. long and moving the bolt and extra .75 or so isnt a big deal to me.
 
The 25/06 case is derived from the 30/06 case and the 30/06 is designed to shine with 165 to 180gr projectiles, so again I ask, why? LOL

At the end of the day, the difference, is none. I wanted a short, compact rifle. I have no complaints of either of the 25-06 I have owned. Just wanted something different, kid friendly, and shooting heavies.
 
A 20" custom 25-06 barrel would get the same velocity as the 25cm probably


Your factory 25-06 would send the 134's sideways into the abyss because it won't stabilize them because they factory twist is too slow

Thank you! Like I said, I wasnt knocking, I was just asking questions! Im ALWAYS in the market for something new and better, but its got to ber a noticable step up from what I already have or have played with.
 
Short actions are also known to be less finicky about feeding rounds. You also generally get better shoulder angles which can help with accuracy. Now, if you built a 7or 8 twist 25-06 it might be interesting.

It's a Tikka action....so "long action" anyway.
Take 90% of the cartridges available today, and there's not a nickels difference out to 500 yards. Out to 1000, it starts opening the gap. And that's nothing you don't already know.
Better be careful saying chit like that. Me saying it cost me a couple friends....and I'm sure got me green striped by even more.
 
The one claim that just makes me scratch my head is how the 6.5cm is magically inferior to anything else out there.
Dunno, I never said it was. You just took it that way. Anything not blowing sunshine up the CMs azz must be an insult!! What I said was....it's no magic wand. Inside 500 yards, it's no better/worse than anything else. My argument was NEVER that the 6.5s dont shine farther out. But most of us will never realize that...as we don't hunt at those ranges. I think you posted something similar to that comment just above....which is what lead to this exchange. When I said it....I was the "uninformed". Just look at your comment about the 243/7mm-08s. Since you have now jumped on the 25CM bandwagon, might as well throw in the 25 Souper.

You just HAD to go there didnt you! :D IMO, the 6.5 cant hold a 7 mag a light to go by, the 300 win blows it away, not to mention what the 300 ultra does in comparison. Forget about recoil, Im strictly talking about ballistics and flat shooting. To your comment about shining farther out, HAHAHAHAHAHA! Any of the above mentioned calibers will kick its arse and take its lunch money. And YES I have shot all of them at distances.
 
Go crap on someone else's thread. Good grief. I bought what I wanted, and will enjoy it. And I hope someone else enjoys my journey.
Well EXCUSE THE HELL OUT OF ME! Threads have a tendency to evolve that way ya know. They start out as one thing then evolve into something else entirely. BUT never fear, thanks to the miraculous green stripe, you wont ever have to worry about me shatting on any of your threads ever again! Good day kind sir! and welcome to the list!

What you really need is a good rail gun. Don't take recoil, weight or the fact that you'll probably need a Naval Destroyer to use it because it shoots flat and that's all that matters. Lol

Well for me personally...I never meant to crap on anyone's thread. But why not just leave it as..."I bought what I wanted, and will enjoy it", like you just stated? I'm good with that. Heck, I do the same thing and you know it.
With the 6.5CM, it's always....but, but, but. It's short action, I can find ammo, it's this, it's that. Now with this one....oh, it's not as fast as a 25/06, but it shoots heavier bullets. Well...a Swede shoots heavier bullets than a CM!! But it's not short action! So, neither is that Tikka!! Well I can find ammo for the 6.5CM, try to find it for the Swede!! Hey, try to find it for that 25CM!! Every argument you had FOR the 6.5 is now working against the 25CM. Guess what else...the 25wssm has a longer neck than that CM. It's short action. It also has that "short fat" powder column fad going for it. Where is it now? Oh yeah...I remember. The 25/06 is faster....Im all about speed. Speed kills!! Remember any of that?
And another thing...you intentionally shot light bullets in it... because speed kills!! Well guess what? The 243 win is faster than the ARC. I know...now we're onto heavies. Guess speed no longer kills?
I personally don't give a yugo what you shoot...or why, but you have gone in a complete circle on this....the very thing you blasted me about, and threw our friendship away over, you are now defending. If you can't see that, then whatever. Absolutely none of it has any bearing on deer hunting in this state for 99.9 percent of hunters anyway.
If your argument is that either is a better bench gun, fine...whatever. But you won't find many 20" barreled, lightweight, bench guns out there, so....
Good luck with your project.... seriously. But stay off my ass when I don't drink the Hornady Kool aid!!
