The 6.5 creedmoor mag from tikka is an M+, so slightly longer than a normal 308 , so that is one solution to seat the bullets a bit further on the 243 case ( short of using an L mag for the 270w). Of course the bolt stop might need a bit of tweaking or swapping over with a long action one.

So the 1 in 8 tikka 243 is finally here! That's great. Would be the cheaper option. Thanks for the info

I have a Tikka T3x .243win with a factory 1:8 twist barrel. It is left handed and two were bought into the country late last year. I am using the 108 ELD-M from the standard 22.4" barrel @2830fps (measured). It is definitely not a hot load.
So far reds and chamois have fallen to it at ranges between 120 and 377 yards. Nothing to complain about the bullet performance although none were huge animals.

With Chris Fisher carbon stock. 3kgs all up.

108 ELD-M loaded to 2.8" next to Nosler 90gn BT factory load.

Does make me wonder how the c.o.l with the 108 will work in the short action 243s though.

Tikkas are all long actions so no issue their

The lands are the limits, unless custom throated a tad longer.

I use the 6CM as my main thermal rifle

Built on a Kimber hunter 22" barrel with Hammer 69 AH at 3900 fps & change

Point & shoot right out to 350 yards, extremely effective with little to no recoil

Its a little light for decent size pigs but amazing efficient on deer

SRP Lapua brass is fantastic

That's pretty impressive speeds.
I learnt to hunt with the stout little 243 so I still toy with idea of getting another one. I wish tikka would hurry up and bring the 1 in 8 .243 into NZ. I just assumed the 6mm creedmoore was the new improved version of the 243. But maybe I'm wrong. I have a 22-250 and a 7mm08 I'm thinking of selling and building some sort of fast twist 6mm. The do all caliber as they say. How does the 108 go on stags during the roar? Thanks for your input.

Barnard SM action AI mag and a 24" Trueflite barrel. Never shot a roar stag with the 108's but any shot into the chest will destroy heart and lungs so they would not go far.
ed just checked load data is 46 gr of Reloader 26 and and OAL is 2.83" in Lapua Brass.

Love my seekins 6cm.
108 at 3000f/s, not hot load at all.
Shot few deer, none took a step. DRT.

Another forum member got it now and sure he's happy.

Those @Fisherman stocks are nice eh?

Certainly are

So a preliminary report. I had my 6ARC barrel opened up to 6mm CM everything same except chamber. Got a couple of rounds through it at last light today. With the sam 103 gn ELDX Velocity had moved from 2880 (and a very hot load) to 3010 ( albeit max) with no pressure signs at all. The expense - an extra 10 gns of powder. Never as much as yer hope for but usefull none the less.

What barrel length @Tentman

22"

I have a 1:9" .243 so not a creedmore but firing the 105gr targex it takes deer out to 500 easy, longest have been a couple over 600 yards.
Plenty of stags have succumbed to them as well. They are doing 2880fps as my barrel is 18" so will go better in a longer barrel creedmore.
