Home Forums Hunting & Shooting Elk Hunting 6.5-300 Weatherby – for Elk?

The hammer forged barrel of the Accugard might be a little over/under the bore of the Mk V and with the softer(?) Interlocks the bore variation may have made no difference. I was under the impression that Weatherby receives barreled actions from Howa for the ‘Guards and if so, may not have been chambered by the same reamers. Just a guess. That variation in MV could be that one doesn’t like the LRX as well. Unless you shot one string, shot the other, then repeated in the same session, your chronograph could be the difference? Happy Trails

Thanks for the helpful comments guys. I went back to the range on Saturday, and the 140gr Accubonds are making me interested in them. My last six shots with them was under an inch. And I called one flyer, and if I discount that one (I know that's frowned upon), the other five were under 3/4 inch. I'm going to go back this week and hopefully make a final decision between the AB and LRX. The only thing about the ABs that bother me is that my Labradar can't see them, and I don't know how fast they're going. So, I could either (1) assume they're going the same speed as the Wby-loaded 140gr Interlocks; or (2) temporarily borrow, and have my brother mail me, the MagnetoSpeed I gave him when I got the Labradar.

Also, on the velocity issue, during that previous session, I was chronoing the 127s on a warm barrel, and I noticed that the chronoed velocities for the 127s were gradually increasing as the barrel got hotter. I posted a thread about that here:
https://www.24hourcampfire.com/ubbt...-velocity-and-barrel-temps#Post15778406. Apparently, that can make a difference.

So, during my last session, I chronoed the 127s on a cold barrel and got an average of 3,420 fps—about 50 fps slower, but still about 50 fps faster than the VG shot them.

I chronoed some more 140gr Interlocks and came out with an average of 3,348 fps, which is higher than before, but, again, that might be because the barrel was fairly warm.

The Sciroccos came out at 3,486 fps.

So, both the 130s and 140s are leaving the MkV at about 70-80 fps faster than they are leaving the VG.

So, I think there’s something different between the two, but I don’t know what it is—not that it matters, I suppose.

Hawk....Brian Litz came up with a G1 BC of .503 for the 127 LRX

Interesting Fotis. It's a bit strange that Barnes would understate their B.C.s (they say 0.468).

Did Litz chrono them at different distances to compute that, if you know?

I’d guess when they’re scooting that fast a bit of difference won’t matter much as long as they’re consistent and it sounds like the AB and LRX are working well.

Be nice to try them at distance to really put a validation on them for accuracy too.

Thanks again Fotis. This is interesting. I went back and looked at some data on my Labradar, and Litz's finding is consistent with what I’m seeing. I know this isn’t they way to do it, but just to see what it’s doing over the first hundred yards, my data is fairly consistent with what Litz came up with.

I went to the ballistics calculator and entered all of the correct conditions. My Labradar says that one 127 LRX was launched at 3,509 fps and was moving at 3,294 fps at 100 yds. Reverse engineering that one leads to a B.C. of 0.496.

One coming out at 3,450 fps was moving at 3,239 at 100 yds. That also yields a B.C. of 0.496.

One coming out at 3,438 fps was moving at 3,281 at 75 yds. That yields a B.C. of 0.502.

One coming out at 3,469 fps was moving at 3,311 at 75 yds. That yields a B.C. of 0.502.

That’s an average B.C. of 0.499

I’m certain that Litz’s methodology and equipment are far superior to what I just did with what I have. But my results are relatively consistent with (only 0.04 lower than) Litz’s 0.503, and are 0.31 higher than what Barnes publishes (0.468).

Again, I’m not saying that my methodology is worth squat by only going out 75-100yds, but it is fairly consistent with what Litz found.

Agreed Beretzs. I will head out to my property in Colorado after I get settled in to my new job I started two weeks ago (I can work remotely). I can shoot out to at least 600 yards there with a decent backstop.



It's about a 15% / 8.5 deg. slope, but I can factor that in.

Looks nice. What elevation and what general area?

Thanks. I got it in a fire sale in 2015. Park County. 9,700 ft - 10,100 ft.

It's got a "cabin" in the interior:





Some nice views:





Kitty cat:



Elk in the summer:



Elk in the winter:



Elk in April:



I have a functioning water well near where the Jeep is. Gonna build right there in the next year. Gonna be fun. With my new job, I can work from anywhere. So, I plan to move there around May 2022.

Standing on that rock, looking at big bucks bedded down below, completely unaware I'm there.

Dear or elk in February. Couldn't tell; didn't have my binos. About 600 yds from the top of that rock. The cabin is about 150 yds on the other side of the rock from the animals. Hence, one reason for my interest in the 6.5-300.

Wow.

You done good. Flatlanders could get jealous.

Am I not reading/seeing your "elk in the winter" caption correctly? You do realize those are rabbit tracks leading from the shed right, or am I missing something?

The "Elk in April" tracks looks more like two smaller tracks right next to each other, and not elk.
It may just be the picture as I can't tell what critter's feet they are from, but unless the hooves are really splayed out and uneven, it isn't an elk track.


I may be in total left field here, but am just not getting those two statements.

Rabbit tracks? WTF?

Big wabbit.

With wabbits like that, one can see why Elkhunternm uses a .460 Wby.



DF

Pretty sure this is the picture/caption Tinman was referring to...

Yeah, I didn't really look at the pic before I posted it. That's a bunny.

You got big enough wabbit gun, or do we need to get elk up there to take care of business?
