6mm /.243 hunting success on Big Game

[Formidilosus]

@Formidilosus , which bullet would you go with? 108?

108gr ELD-M is easy. They both work.

The BC isn't quite as good as advertised when shooting to extreme ranges. I found them to be a 286g7 for waterlined dope to 1300y. However the advertised numbers work to 800. Just goes to show small variation in bc doesn't make a difference till you're long ways out.

The 112 Barnes is the sleekest option 6mm has. I've verified a 308g7 to 1100y with mv from 2910-3080. It fragmants very hard, prob not ideal for close range shots. I'll be testing the 109eldm and the 112mb this fall at 6cm and 6prc velocity from a lot of ranges on deer elk and Antelope. End of season I will do a large picture/data dump.

Thanks for the info.

What twist rate barrel? I see they recommend at 7 or 7.5 twist.

I've shot them in 7.5 and 8 without issue, my da is typically 4-7k depending on season. Most my 6mm rifles are 7.5tw, I feel it's the best balance. 6mm short mags are 7.75 and 8tw due to the extra velocity.

This has been my biggest deer to date, body and rack. Approaching 300lbs on the hoof and a 7x9 that grossed 204".

485yds with a 6x284 with a 115 Dtac.

I've been more than happy with using a .243/6mm variant although some are a little better than others. I have a Dasher that's fine for a couple hundred yds, or for doe, but I don't think I'd really want to shoot one 500 yds with a dasher.

You said 105gr Berger hybrids in the video.
Congrats on the buck.

Good call, At that time I believe I was using hybrids. I switched shortly after for shooting matches to 115 Dtacs for higher bc and less powder to burn and never looked back. I have a decent one on the wall I took a few years later with 115s out of a Creed

Are these the older open nosed dtac? Or the newer closed nosed pointed unit? Are they nose ringed? I'd think your short barrel 6x284 would be similar to a 24-26" 6cm velocity wise.

The rifle isn’t my cup of tea. I do like your caliber choice though.

Congrats on a stud deer and nice looking rifle. Gives off an m2000 intervention vibe

What velocity are you getting out of your setup?

 

[Duh]

Got another sweet data point. 60 yards frontal shot on a big bull. 6 creed with a 108 eldm. He made it 75 yards and piled up. Hope the video uploaded fine.

 

[khuber84]

Great bull! Oh how sweet it'd be to be able to hunt elk in rut with a rifle! Not in Montana.......

Thanks. I’m extremely lucky to have the tags I did this year.

How deep did the wound cavity progress from frontal impact? Make it past the diaphragm wall to guts?

It went somewhere into the guts. I never recovered the bullet but the lungs were complete mush. It was a bloody mess inside and dark so I didn’t do a good job of getting pictures. Just got him quartered up and packed out solo.

We can but just in backcountry units. Unfortunately since the release of the wolves those areas aren't as easy to find elk in anymore.

Broke in the 6mm CM yesterday evening. Doe cull on a bean field. Shots were from 325-485. 7 does and one cull buck were killed. 2 were shot with a friends 7 mag. 6 were shot with the 6mm. 4 with the 103 ELDx and 2 with the 108 ELDm.

I didn't have time to do any autopsy pics but no deer ran more than 10 yards most were DRT. I couldn't tell any discernable difference between the 103 and 108s, but it was kind of difficult to tell which deer were which upon retreival in the dark, as we were in a rush to get them to the processor for donation. 3 exited on "shoulderish" shots.

I feel entirely confident with either load though. The 103 ELDx is running 3050 fps and the 108 ELDm is running 2915 fps. Gun is a Tikka rebarrelled with an Osprey (not a prefit), 1-7" finished at 19".

What velocity are you getting out of your setup?

...and what is your recipe? Brass, COL, powder/charge, and primer? I have a 25-284, and am curious where it stacks up to the 6-284. I'm running a 22" barrel with 134 ELDM over 54.5 grns of H1000 and should be around 2900 MV, but still need to chrono.
