Dose any one own one of these?
I have one, but i haven't put much effort into getting it to run right. I would like to send it to Ted Gaillard and have a new 1-8 barrel twisted on it so she can run the heavy bullets.

Right now its a 1 in 12 R.O.T in other words a supercharged 22-250.

Whats your favourite load/recipe
 
I've had one briefly and then went to 22-284 with a 1-8 twist, MISTAKE....I have now bought a 1-12 twist for my 22-284. I vaporized 80gn SMKs at 3750 fps in the 28" 1-8 twist Bevan King barrel. I just read a good article on 22 cal twists and velocities a couple months back in either Handloader or Rifle Mag and they were able to stabilize an 80 gn bullet in the 22-250 with a 1-10 twist at about 3300 IIRC. Point being try your 22-243 first as I think you already have a winner. You will have to get them up over 3500 fps though in a 1-12 twist but that is no problem with that case and I assume a long barrel.
RL19 and slower are your only friends with these case capacities and 80-90gn bullets, H4831SC is another good choice as is RL22 and IMR 7828.
Calculations show the 80gn SMK to be stable with an RPM of 210,000 as a min with a max of around 240,000 RPM, my 22-284 was cranking them out at over 330,000 RPM and as I said vaporizing them about 30 mtrs out. Now with the 1-12 twist I should be in the correct RPM range from 3500-4000 fps. Your 22-243 should easily get into this range as well assuming a barrel of 26" or longer.

Hope my experience is of some help to you.

I had one in a 14 twist and it was a gopher vaporizer... for a couple of weekends. I used to shoot 55 grain nosler BT's at about 4 grand with Varget. Seems to me it was around 43 grains. Don't quote me. Ridiculously overbore cartridge but fun. I still have the old barrel sitting here.
 
I've got one, thats been set up with 2 barrels. The plan was to set up the original 1-14 22/500 barrel for fire forming, then swap in the fitted 1-8 Lilja barrel once that was done.

Trouble is, the fire-forming barrel shot too well to abandon, placeing 5 52 grain Berger match in the same hole when things went right. Eventually it was time to stop delaying the project, and the remaining cases were formed and barrels swapped.

I tried 90 grain SMKs first, since I had a few thousand I'd picked up on the EE. That didn't work out, as about half of the bullets blew up in the air. Next I went with the 80 grain Berger and 46 grains of H1000 for 3600. Haven't seen any need to veer from that course at all.

I suspect that if I was doing it again I'd go for a straight 22/243 with no neck turning, shoulder bumping and fireforming. My tolerance for pain in the butt case forming isn't as high as it once was.
 
Thanks a bunch guys...... c-fbmi i really like the sounds of that 22-284, i had looked at one another guy was selling on Alberta outdoors forum and i passed it up thinking this 22-243 was the end all be all. Dogleg when i had spoke with Ted Gaillard he said (Quote) "Why the hell would you want to create more work bumping shoulders and fire forming brass with a middlestead when you can run a straight 22-243 win". He also said that he has built middlesteads that have went well over 2500 rounds and still hold the same group as when it had left his shop. As long as the load isn't over the top HOT. I guess after ample years in the barrel making industry and holding a wall of championship bench rest titles, i should probably listen to him.
Thanks guys!!

Yep, that's about how he'd say it. There was a bit of rethinking and reamer buying in our little circle awhile back.
