When loaded to their full potential I would say the equal, both exceeding each other in different areas. Take the new 131 black jack and it makes the 25 cal a different critter. However, despite their advertising claims the difference between it and a 6.5mm with a 150 smk aren't as much as they say. I've ran the numbers for multiple scenarios and the 6.5mm always hits with more energy at long distance with pretty much identical wind drift. The 25 cal will always have the advantage of speed, and less recoil.
What velocity can be expected with either out of 25.06?
My 264 runs 130 gr. Swift Scirocco at about 3100 to keep it sub MOA.
I was hoping to hear more on performance from the guys who got the first batch of barrels and reamers to shoot the 131 BJ bullets.
To say one has an advantage over the other you have to compare apples To apples. Comparing a 131gr in a .25 to a 140gr in .264 is not really the same. That's similar to comparing a 115 gr .24 to a 115gr. In a .25. If you scale the bullets a fair comparison would be a 150-155 gr bullet in a .264 and the heavy bullet will win out on ballistics.
Anyways I have both 25-06 and 6.5-06. Even through the 25 is ballistically less than the 6.5 it always manages to find its self out of the safe for at least one hunt. It is still a great round for its purpose.
TX Badger, my Oehler chrono tells me my 25.06 runs the 110 at about 3140.
A 284 version should be about the same(?). Are you telling me this Blackjack bullet will run 3200?
Not trying to pee on the fire, I'm cautious. I'm a 25 fan too.
He specifically said that the 25 Creed was shooting the blackjack at 3000. I've never seen anyone shoot a 6.5 Creed with 130 grain bullets at 3000 so I'm just wondering how that's done with all things being equal except bore diameter. In my experience usually you get faster speeds with the same weight of bullet in bigger bore diameters. For instance, you can shoot a 168 grain from a .308 faster than a 168 from a 7-08.
I missed where he slipped that part in. I agree might be a little optimistic. Especially the x47 at 2950
Just out of curiosity, what speeds are you running the 131 at vs the 150 smk in say a 25 creed vs a 6.5 creed? I just want to hear what velocities your comparing the 25 too as I have some pretty extensive load development with the 6.5 and know how much velocity its capable of. Not knocking your bullets I think this is a great thing you guys are doing.Out of the same parent case the 131 will come out ahead in Wind, Trajectory, and Energy for about 1500 yards to a mile in every instance we have looked at it with actual achievable muzzle velocity data.
I knew this would be the case in the general sense, the 131 ACE is one of the most efficient for weight copper and lead bullets ever released to the market, if not the lowest with the lowest G7/I7 form factor.
The 150 smk is a great design but pushed from the same parent case due to achievable muzzle velocities it will take serious range for the 150 smk to catch up.
As I mentioned on another thread, our "Claims" of 0.330-0.333 G7 were simply reported test data. The market has affirmed that these numbers were in fact cautiously low. Most competitors are reporting 0.345-350 G7. There are two major reasons for this - #1. in the production run we focused on getting the noses sharper and #2 our boat tail is the longest-for-caliber of any we have measurements on.
When Blackjack Bullet #2 comes out this year, we will have to endure another round of healthy skepticism from the market. : )

150 smk in Peterson brass with rl-26 2815. 147 eld in hornady brass and rl-26 2903. 140 eld-m in hornady brass rl-26 2945(accuracy node). 140 eld hornady brass rl-17 2883 fps. 147 eld in hornady brass rl-27 2823. These are just some loads I've come up with over the past couple years that have ran well for me all out of a 26in barrel. I just started the 150 smk as winter came so I still have exploring to do there, and I ran out of rl-26 so I'm waiting to find more of that. If I ran the 150 smk in hornady brass it should equal or surpass the 147 due to the smaller bearing surface. Currently my load im running is a 140 eld in Peterson brass at 2773. It just shoots well there so I'm leaving it. Hornady brass gives me alot better velocity but peterson is way more consistent. Waiting on my barrel to get back from being threaded so I can do more development with the 150 and 147 with rl-16. I'm expecting to top out around 2775-2815ish. This is going to be in adg brass which so far from what I'm seeing can take more pressure than Peterson can. When I'm comparing I run the 150 smk at 2800 which is book max from sierra in a 24in barrel just in case my barrel is abnormal. All my calculations are run through hornadys app which has been spot on for me.What is the top velocity of a 150 in your 6.5 Creedmoor? What brass, barrel length, and powder?
