6.5 cm vs 300 win mag
And just to provide context and a different way for people to view things...
6.5 cm 147 gr vs 300 win mag 200 gr Factory Hornady Loads Exact same penetration (sd.301) 6.5 cm has 55.4% less recoil 6.5 cm has 26.5% less bullet weight 6.5 cm has 5.4% less velocity That is a shat ton less recoil energy giving up very little everywhere else that matters. Basically maintain same velocities at same distances all the way out. This is the magic of of the 6.5’s... The Grendel 123 gr does this to the 308 168 gr, almost identically the above. The PRC 147 does this to the 338 Lapua 250 gr. Not as close as the two examples above but still so close as to compare. Maybe this helps big picture the actual real world differences better? And show why it’s not hype and marketing. |
Having the same S.D. does not mean that they will both penetrate exactly the same amount. And even if they did penetrate the same, if both bullets expand by the same percentage, the larger diameter bullet, will have a larger frontal area, which should produce a larger wound channel. If it really is as simple as having a high S.D. , why not just load up some 100gr .224" bullets for hunting Alaskan Brown bears? :rolleye2:

The SD value only holds up for a fully intact bullet. It is not the end all be all.
The 300 win mag will penetrate more at the same distances as the CM |
Which would rather you shoot an angry grizzly with if you had to not stirring the pot im a big 6.5 fan but I know my answer.
|
I bet the 300 carries way more energy all the way and will buck the wind better

At an impact velocity (say 2000 fps), a bullet slows to near zero in about 20 or so inches .. all in a millisecond. With the velocity gone, along with the remaining kinetic energy, where did all that remaining energy go and what is the force that keeps that bullet moving ? Just curious.

Not knocking the Creed or Grendel. But I leave my 6.5x47 at home when I go elk hunting. I feel way more confident carrying my 300 Win Mag with 215 bergers. I’m getting into smaller calibers and the 6.5 is great. But everything has it’s limitations. Depends how far you shoot and placement trumps everything. I posted some numbers in your previous thread. Energy foot pounds isn’t even close when comparing a 6.5 130 gr to a 30 cal 215 gr. I got to run the 147 gr in my Sherman this winter. But again not a fair comparison to the Creed. I’ll drive the 147 around 3200 fps out of my Sherman. Will be impressive I think.

I am genuinely curious as to what you're agenda is on this thread and the dozen other 6.5 threads?

Appolagize for rambling and not anti creed at all its a fine cartrdge but numbers dont always mean everything and I do see the merit in your points vs recoil you pay a lot for a little more horsepower |
Simply perspective, different way to see why. People have a hard time getting over long stigmatized names or figures that don’t matter like they thought etc. Percentages show how little difference things that people think are big differences really are and how big the differences are that really matter on the trigger side of the equation.

Anyway I do respect your passion for the 6.5 cm. |
I heard that the 300 Winchester is the best.
Dang,,, the world keeps changing. Ha |

As for the bear hunt I’d be perfectly content with any appropriate for game impact velocity, sd and bullet construction. I’d likely be after sd over .3, delayed controlled expansion bullet, and impact velocities north of 2200 fps. |

Why does it always have to be an Alaskan brown bear?
How many grizzlies were shot in Alberta last year? How many of you even had a tag??? You guys do realize this is about penetration, at least that’s what I got from the op. Fwiw, I doubt anyone would choose a 6.5 Grendel over a 300 magnum if they were grizzly hunting, but being that most of us on the forum live in Alberta I don’t understand why it always has to come back to grizzlies. I’ll bet 99% of the people on this forum haven’t even seen a grizzly in real life. I’ve seen a total of 5 in my life, and one was in the park. Never once did I wish I had a 300 magnum when I came across a grizzly. The topic is about penetration, maybe leave the grizzlies alone since they’re protected. :sHa_shakeshout: |
I dont think his knowledge is anywhere near what he would like us to believe.
So much for spreading the knowledge base |

What I’m saying here is that good shooting goes well, marginal shooting goes marginal, lousy shooting is a lottery....and none of it really affected by cartridge choice. Unless you’re shooting lousy because of the cartridge. Other than that I fully expect my Grendel to deliver average results over time and as a direct reflection of my shooting ability. Just as I would expect out of all the other cartridges I’ve shot or been witness too. There’s no surprises in any of it. |
