Home Forums Hunting & Shooting Ask The Gunwriters Kimber 1" accuracy gaurantee

Just to keep a comparison apples to apples, run the data on a 6.5, 140 gr Accubond, BC .509, at 2750 from the CM vs. a .284 140 gr Accubond BC .485, at 2800 through JBM, be honest about what you find & get back to us.

But here's what you'll find:

Given a 10mph 90 degree crosswind, at 500 yards, the calculated windrift difference is 0.2 MOA.........not exactly a deal breaker, from a hunting perspective.

But maybe the real life difference is bigger.........I don't know.

Yeah, comparative BC's will favor the CM, but given similar, but marginally lower, BC bullets in the 7-08, the performance differences are marginal.

But, if one is starting from scratch & has no 7-08, yeah, the CM makes some sense, but in the end, the 7-08's bullet selection & ability to handle heavier bullets, makes it a better overall choice for HUNTING.

Just my view; surely, data can be compiled to support whatever view you might want to take.

So many are missing the point. Can you buy a factory rifle in 6xc and pick up good ammo at the store?

Exactly, and at $26 a box right now. Good factory ammo for my 7mm-08 starts at nearly twice that. I know that's not a big deal when you reload everything but it can never be a bad thing.

You can buy a factory 6mm CM?

Factory Nosler BT ammo for 7-08 with 120's is $29.99 everywhere...

Yessir! If a guy can run binderless AICS mags at 2.950", the tables turn a little. I'll be interested to see the final numbers on the 7mm 180gr ELD...

$20 if you catch it on sale at SPS... 😉

WTF man........that would be the beauty of making the other creeds standard. That's all hypothetical but obviously going over heads.

I love ballistic tips but please stay with us. Shoot your 29 dollar 708 ballistic tip ammo against some 143 hornady ammo. Good high bc ammo is available for the creed and they're all twisted to work.

Hell I don't even have a 6.5 creedmoor because I have custom barreled/twisted guns I handloads for. The whole point is a turn key setup over the counter.

Oh man, this is epic. Or maybe uber. Or maybe epically über. Or überly epic.


I got some 7Mag Corloks for like $22 that shoot all day long if I do my part.

MontanaMan,

In the real world, the .509 BC of the 140 6.5 AccuBond is correct, but the .485 for the 140 7mm AB is BS--it's really more like .430.

Ok, that would be enough difference to be significant.

Just going by what Nolser publishes, guess you'd have to shoot it & measure it to know differently.

Which is why I recommend Bryan Litz's book of range-tested BC's. Many shooters would find it kinda pricey, but it saves plenty of ammo and time.

I admit I am at a loss. Has this thread has turned into an "I don't like the 6.5 CM and that's why it isn't going to be popular regardless of how popular it is or is becoming." thread? Additionally I think it's funny that once you put a 6.5CM in a standard length action, it suddenly becomes "worthless" or there is no point in owning it. Why? Rhetorical question.

Why not toss the 143 eldx or 140 Berger into the mix? Or the 123 scenar?


And, a steady 10mph 90 degree crosswind would be convenient, but rarely happens.

Hell I have an 8.7 twist custom 7-08 and I still want a Creedmore to play with.

Yep.

Many of Litz's BC numbers are included in JBM's database of bullets, but not for the .284, 140 AB, but his BC's are included for the BT's & Partitions.

Exactly. For custom rifles and hanloadeers the creed idea isn't the end all be all. For all over the counter it's pretty cool. Nothing more nothing less

I doubt I'll get rid of my McWhorter 7-08 for a 6.5CM anytime soon, as it is a very effective killer out to 600 with 140AB's. It's fun to crunch numbers and speculate though.

Got my first Montana about 5 weeks ago. I put two small spacers made from a business card at about 7:30 and 4:30 on sides of front receiver to increase float of bbl. then tighten screws. Mount Leupold 3x9 ultralight scope using Burris rings with floating inserts.
WW cheap bonded bullets...first three into a ragged hole at 100. Then Fed Classic blue box...same but now about .300". Both 130's.
Shot gong at 400 about 10 shots. 100% hits.
Went and had lunch!
Bought alloy bow and Ti handle...KEEPER!

That sounds good! Congratulations!

So Rick, how much has your cartridge choice and rifle weight changed since about 15 years ago when you swore off being a rifle loony, and bought a rifle from a certain well-known maker? And how many rifles and cartridges have come and gone in between? :-)
