6mm /.243 hunting success on Big Game

[Floridave]

I hope to be posting some success photos in this thread soon, well 5-6 weeks anyway. Final load testing for the new for this year 243, 5 rounds each at 100 and 200 yds with 105 Bergers and 108 ELD-M and I’ll decide which to go with for the year. Honestly I could just as well flip a coin, both shoot very well and are just at 3200fps.

Finally got to put the 6CM I got for my wife to work. We each took an antelope and the factory ELD-M left impressive wound channels. I'm hooked.

What distances or impact velocity were you at? I’m using 6CM this year also with the 108 ELD M

 

[MuleyFever]

They were both about 200yds. Velocity was about 2560 at that distance.

My wife shot a whitetail doe this morning with her .243. 95 grain Nosler ballistic tip, roughly 2500ish impact velocity. Slight quartering to, hit a little high and back. Exit was right at the diaphragm. She ran about 25 yards. First pic is entrance, second is exit.

If I was wanting to shoot 115 DTAC’s from a 6CM, anyone have a recommendation on how short of a barrel I could get away with to achieve a reasonable 2,800 fps muzzle velocity?

Won’t be hand loading myself, atleast at first. I’ll have Unknown Munitions load up ammo, so can’t push loads hotter than what will come from them. I’d like an 18” barrel, but would go 20” if needed for 2,800.

@B_Reynolds_AK I think you will be cutting it close but likely right there with 18" depending on how hot they will load them. I am running a 22" Preferred prefit at just under 3000 and a buddy is running a 20" and 108eldms at right around 2900 if I remember correct. We are both at 40gr of H4350 so not a super hot load.

Great info, thank you.

I am at around 2840 with the factory 108gn with a 20" barrel.

Another data point for you. My 18” runs factory 103 eldx at 2840 fps

Here another one, 2660 fps from my 16” barrel shooting factory 108 eldm.

That is surprisingly slow for a 6CM. I get about the same speed with factory ammo and AR15 level handloads out of 6mm ARC, 108gr ELD-M, with a 18” barrel.

Editing to add, I don’t own a 6mm CM, but that seems slow.

I know. I thought I would at least get 2700. This barrel only has about 40 rounds down it though so maybe it’ll speed up.

You may get there!

After the .223 thread, I'm convinced the .243 would be perfect for Cape Buffalo.

Broke in my 6 creed tonight finally. Antelope at 160 yds. Factory 108 Eld-M at 2746 (18” barrel suppressed). Impact should’ve been about 2530. Ran 20 yards and locked up the brakes and started wobbling. Dropped with a second shot. Super happy with the bullet performance. I clipped the edge of both shoulders and there was very little meat loss.

My wife broke in the tikka 6mm arc on Friday, 108eld at ~1850fps impact velocity. Hit at the base of the neck, not 100% if there was more wind than I guessed or the steep uphill angle and her not leveling the bubble maybe both? She’s a great shot but this just showed me we need to work on communication and fundamentals more. Overall very happy with this little rifle and looking forward to using it more in the coming weeks.

Are you still getting that little 6mm ARC to run well out of the factory Tikka "M" mags? I have thought a 6BRA or a 6 Dasher would be sweet, but I would want to run factory mags.

Yessir, at this point it has still cycled 100% from the factory mag. Maybe about 100 rounds or so cycled from the 3rd mag as of now

Well I had been really searching for a 8 twist 243 tikka since I can't legally shoot elk with a 223, but now you've really got me thinking of a 6ARC since I've got about everything but a barrel laying around to do an ARC AR build....

Factory ammo is a lot more reasonably priced than i figured as well which is nice

Anyone have velocity data for the 108 eldm out of a 16" barrel??
