Hello,

I think I've gotten the go-ahead to build a MH.

I've posted my question in "hunting" cause that's what I'm building it for.

My first thought was .308, but I see that .260 and 6.5CM are options too. I have easy access to very good quality .308 reloads already.

I'd like to have the most capable hunting gun possible - deer, moose, elk, coyotes. I'll likely play with it at the range a bit too, but I have much more capable bolt actions for serious range fun.

Would you bother with the Proof barrel to save .8lbs??

Guidance please!! It's a big investment - I wanna do it right!!

Thx.

-J.
 
Ardent just did a write up on his website. In terms of the most capable hunting cartridge, of the three, I would have to recommend the 308. Not sure if I'd go with the Proof barrel or not. They're a heavy platform so I would have to give serious consideration to dropping weight where I could.

How do you think the carbon barrel would handle 50-100 rounds at the range??

That question would be better directed to Rick. Carbon barrels don't heat up as fast as steel barrels but you can bet the farm that the thin steel liner in that wrapped barrel will get just as hot in a shorter period of time due to the extra insulation and will stay hot longer (meaning cooling slower), again, because of the insulation value of the carbon wrap. I can't see that working well for a high volume platform like a rifle you're going to take to the gopher patch, but for most hunting uses you won't notice that. 50-100 at the range? Well, you had better be planning an long range session with lots of other stuff to shoot in between while you wait for the barrel to cool.

I'd sure like to see someone do a side by side comparison of carbon wrapped and traditional steel barrels to see which lasts longer under the same usage.

What the f@#k is an MH ? Who is required to give the go ahead?

Is it really that hard to spell it?

It's a Modern Hunter from Alberta Tactical Rifle. I'm guessing the "go ahead" is from his significant other since the rifle has a $3,500 price tag before optional add ons.

Good for you. I'm sure your experience is invaluable.

Spelling is not hard for me, and neither are acronyms. Especially acronyms that pertain to a rifle that is discussed several times a day on this forum.

If you must know, my Wife's permission is required, because I respect her and taking $4500-$5500 out of our household coffers without asking is disrespectful in my opinion.

If you'd like to ask again, nicely, I'll be glad to tell you.

Actually from our testing of the Proof barrels they heat up faster and cool faster than a conventional barrel does. Quite a bit faster on both counts in fact. This rather defies common logic, but I assure you it is the way it is with Proof barrels.
What we did see is that regardless of how hot the barrel got the POI did not change nearly as significantly as a heavy contour conventional barrel does.
The science escapes me but the proof is in the testing.

For more info see here.

The big advantage ofcourse is the weight savings. To have the all attributes of a heavy contour but the weight of the lightest contour we offer is a great option. Cost is the only downside in my opinion.

Thanks for everyone's input so far!!!

Rick - 18.6" is more or less just as good as 20", correct?? Dustin says the FPS loss is minimal.

With factory Federal ammo we saw a whopping 18 FPS difference between 18.6 and 20" barrels. Both were Proof barrels but we did not air gage them to see if there was any dimensional difference. Now 1 has to understand that there can be greater differences depending on how tight or loose the bore is. It is amazing what a tenth of a thou will do to velocity.

FWIW ALL of here at the shop opted for 18.6" barrels.
