6.5-300 Weatherby for Long Range Shooting

[bearpaw]

I'm more of a hunter than a regular long range shooter and I don't mind buying a new barrel if needed. I'm still seriously considering this cartridge if I can find one for sale! 

[TVHunts]

I gotta believe it would flatten anything out but,  barrel life as stated would be very short I would guess.  I know of and have had a .264 WM rebarelled in less than 500 rounds. 

A guy better be lucky on figuring out a round it likes quickly!

IMHO, for anything that is going to get a lot of use, 6.5-06 is plenty fast. We got one that is pushing a 140 Berger Hybrid at 3100!!

I like the ballistics of the factory ammo with the 130 gr Scirocco at 3476 fps. Here are ballistics sighted dead on at 300 yards at 5000 foot elevation.

That is pretty dang flat bear paw! Looks like things could get messy on the close end! 

With that case I'd be looking on the heavy end. 142 ablr in factory ammo? Or 143 eld-x?

[WoodlandShooter]

Yeah, 143 ELDX would be supersonic to 1700 yards.

assuming 3315 MV and standard conditions.

I found some data on the Nosler 142 Long Range Accubond, I couldn't find solid info for running it faster. In reality you might be able to load a little hotter. I don't know what the ELDX bullet is?

The ballistic coefficient on the 142 LRAC is crazy good!

[WoodlandShooter]

LRABs are usually high by ~ 10% or so.

for example, the 150 in .277 is advertised at .625, while in practice, they are actually .582

[bearpaw]

That certainly makes a difference that they overstate the BC, I ran the ballistics again with a 650 BC.

I can't find any 6.5-300 wtby's for sale yet, but had a new idea, I've got a 300 wtby that needs a new barrel, I called Benchmark and asked about putting a 6.5 barrel on my 300, but they said there isn't a standardized reamer available yet. I was told to wait about 6 months and then check back. I'm going to wait a while and then check again to see if a standardized reamer is available. (Chris at Benchmark was extremely helpful, thanks much Chris!)

Since they 26 Nosler is a twin to a 6.5-300wby why not just do a 26 Nosler and not have to wait??

[Reidus]

Or order a reamer from pt&g.

[bearpaw]

The 26 nosler is a little slower, once the weatherby hits the market I imagine a standardized reamer and cases will be more available, so I'm willing to wait. I saw a couple wildcats, 6.5 RUM and a the 6.5 PRO which is supposed to push a 140 at 3700 fps! I may have to learn more about those while I'm waiting.

[jackelope]

I think it's what the 26 Nosler should have been! If you're going for a hyper velocity 6.5, why not to with the fastest? I do wish they had gone with a better bullet in the 140 class. The A-Frame is a great hunting bullet but has the BC of a brick. It doesn't make much sense in a long range gun/cailber. Handload the better 140+gr bullets and it will be even better.

Now if you really want to get a 6.5 bullet moving you can give the 6.5 Badger or 6.5 RUM a try. Why shoot 140s at 3400fps when you can hit that with a 160 with a better BC?

Another one is the 6.5 STW. I was going to do a 6.5-300wby but with all the 7stw cases I have been buying I decided to go with the 6.5 STW. It and the 6.5-300wby will run pretty dang close to the same and both a little faster then the 26 nosler.
