6mm /.243 hunting success on Big Game

[blksno]

...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.

With 105s and a 19" barrel, I was a comfortable 3300fps.
Lapua Brass, GM210 primer, and RL26.
When I switched to 115s, I reduced the charge to keep it around 3150 to stay legal for shooting matches.


When this barrel is toast, I will likely rebarrel to 25x284 now that there's a good option of high bc .25 cal bullets. (and I have plenty of more efficient 6mm rifles now)
I feel like the 284 case is far better suited for a 130+ class bullet. You're burning a LOT of powder for a 6mm bore.

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.

I have used them all, original open nose, new close nosed and I have 1500 of the new nose ringed...but I havent tested any of those on game yet.
I really didn't notice much difference with the open or close nose.

I have no doubt a 25x284 will end up at or well above 3000. Even with a 22" barrel. My 25 Creed is at exactly 3000 with a 25" barrel

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

I actually dropped the barreled action into a Manners folder. (Put a 14.5" 308 into the chassis)
6x284

308 throated long for 230gr pills

Right on. Given my location (California) I’ll be running the heavier hammers or one of the other non-lead options. Gonna need a long throat I think, but a 104 grain hammer at an easy 3400 sounds pretty legit.

Any progress on this? As another California guy I’d be curious what your results were with the non lead options.

I'm getting very close to 2900fps out of an 18" 6 Creed with 108 ELDMs and 40.2gr of H4350. Not sure on your barrel length but that seems to be a big discrepancy in powder but I'm sure you couldn't use that much 4350 without pressure.

I’ve heard 42.4 gr of h4350 out of a 16” getting 2950 with the 108 eldm

 

[deer_hunter132]

^^^that sounds a bit over pressure.
6cm has a little less capacity than .243w, and book max is 41.1 h4350 and WILL NOT get 2950 with a 108 from a 16".

It seems the 108 eldm is the favorite for the 6mm Creed, but the Berger 108 elite hunter looks like I can get another 100 ish fps at 500 yards due to the better bc. Is there any reason the eldm performs better terminally? Provided accuracy is comparable, any real advantage to the berger?

None yet. This will probably be a 2025 rifle. That said, I’ve had good luck with the 110 Barnes in 30-06. You can push it fast enough that it can act like a hammer-ish design. So far it’s dropped deer without issue. I’m sure a 243 cal 104 grainer with a better bc and a higher starting velocity will work equally well or better.

Bergers are going to penetrate farther, longer neck length, before they begin to expand. If you want a better bc ga precision sells a 109 eld-m that has a g7 bc like the 108 elite. The 108 elite is a great bullet though.

I am having analysis paralysis on 108eldm vs 112 match burner for elk. I have both. Both are accurate. I can push the 108 to about 3100 and the 112 to about 3050.

No one is getting exits on elk with the 108, right?

I don't think I posted these yet? Maybe. But, it's relevant to your question.


18" 6 CM, 112 Match Burner M.V. 2918

525 yards from a standing tripod position. 2 shots, one right after the other. Moose was down within 3 steps.


First shot double lunged him. Significant internal damage. Bullet caught on offside hide.



Second shot entered into front of front quarter. It broke the thickest part of the sternum. The jacket was caught in offside hide, but the detached lead exited and left an exit hole.






I have a cow elk tag for Raspberry Is., here in Alaska, that I will be hunting in November.
The Roosevelt Elk on that island, as well as Afognak, are the largest bodied elk around.
I plan on using the 112 MB there as well.

Yeah light and fast is the answer for copper. The 80 TTSX runs great out of my .243. But it definitely limits range because I won’t go blow 2000fps with monos. Haven’t ever messed with hammers. Too many horror stories from people I know over the years.
I’m going to be exploring other non toxic options. Lehigh defense controlled chaos, and bulldozer….etc.

The book max in Hornadys is 42.4 of H4350

I shoot 41.5 grains out of a 24 inch barrel and 108’s are going 3150

Hell, maybe my experience with .243w is just crap. Take anything i say with a grain of salt i guess.

I get the feeling hornady favors published load data for the CM stuff so it looks better on paper, idk. If you can get 5+ reloads from the brass, then its probably ok.

Thanks for posting that - those pictures make me happy, lol. Round looks wicked.

Yea I aim for 2400 or better with Barnes. Might be unnecessary to keep them that fast, but it’s been a no-fail policy so far. Whatever direction you go (projectile), I’d be interested to see your results.
