I have had one for years. There are different versions, but mine is a standard 22-243 winchester. It is built out of a Remington 700 short action. 26" Shilen select match Sendero weight 8 twist barrel. I use Winchester brass, 48 grains Rel 25, 75gr Amax, and Fed 210. I will be switching to Retumbo and Cci250 when I can find a load. My dies are Redding. I like the standard 22-243 because you have no fire forming. Take a 243 brass, run it in your sizer and you have 22-243 case. I love this gun and will own one the rest of my days. I don't even shoot my 22-250 or 6mm anymore.
Don't build a 22-243, build a 6x284. With a 30" barrel, it will shoot a 70grn BT at 4000fps , an 87grn V-Max at 3700fps and the 105grn A-Max at 3500fps. All you have to do is neck down the 6.5x284 Lapua brass to 6mm, load and shoot. Also, there is a bunch of reloading info on it and the 6mm poly tipped bullets have a much higher BC than the .22 cal bullets.
Try and google reloaders nest, or handloads.com. They have several loads and velocities listed. Welcome to lrh, try a search for 22/243 or check the varmint section there should be some info there.
As far as the 6x284 its an impressive round, however during elk/deer season I am not allowed to hunt coyotes with anything larger than a .223 diameter bullet. 10bruce might be in a similar situation, I have a 1'7 twist .223 that I might chamber in 22/243 but will probably go with a 22-250 AI because a friend has a reamer and an extra set of dies.
I think teh 22-250 has 46grain water capacity, the 22-250 AI has 51 and the 22-243 has 54. So 22-250 ai load data would be a good place to start.
I'm in the process of building a 22-243AI. I'm just waiting on the action now. The 6x284 is a good round, but wildcat is biased. The 87g vmax has a bc of .4. You can send a 80smk bc of .420 at 3700 out of a 22-243AI, which would make it a toss up. There's a guy on the savage forums who screen name is outlawkyote, and he claims that the bc of the 80g smk is .6 at 3500fps. Sierra has it at .420 at 2200fps. Either way, they're flat shooters with lots of potential.

I am a 22-243 owner for life too, it is a very accurate round fun to shoot. I shoot 47gr retumbo and 90gr berger vld seated .007 into lands of a hart 1-8 twist. I have 243 and others and I always go for the 22-243. I have all my loads posted on reloadersnest. Build it and have a blast shooting yotes way out there.
