If you have a Smith open up your bolt face (super common operation) and install an M16 extractor or the like, use a Wyatt 6.5 Magazine (2.995), you open up to more power than you'll likely ever need. A wildcat you should consider in this case is the Sherman 7mm SS. You also then host a 7 WSM or the very popular 7 SAUM.So I have the action which is a 243 right now and leaning towards not having to buy a magnum bolt since I have a 7wsm already. Goals for this project are basically putting together an all around deer rifle. Quick deer drive type shots as well as get down and send one when the situation warrants it. I already have 7-08 brass so there is that part of the equation but to me that is not the deciding factor. Yet..
One question I haven't found a clear cut answer to yet is the real world velocities from the 708 vs 708 ai in longer barrels.

where can I find info on that? I thought the other day that would be a cool wild cat.

If you go to the 7SS route make sure you get one built with the 7SS version B reamerIf you have a Smith open up your bolt face (super common operation) and install an M16 extractor or the like, use a Wyatt 6.5 Magazine (2.995), you open up to more power than you'll likely ever need.

7/08 AI-140s at 3020 on 26, 9T" is real world with H414, throated appropriately, 3100 was maxed but not as accurate. I run Wyatt's extended internal box magazine allowing more powder space.
284 needs long action, I made the mistake with two barrels on a short action, and never again.
284 = 280 Rem

7 PRC case volume duplicates the 7 Rem Mag. I have not had an issue with a belt in 35 years.
Opening up the bolt face, and adding an M16 extractor is half the battle. The next obstacle is the feed rail adjustments for the much fatter case.... a hard lesson learned!

If you already have the action and it is a standard bolt face, I wouldn't spend/waste money on opening the bolt face and adding an extractor. Been there, done that..... Go with a 284 Win or a popular wildcat version of it like the 284 Wheeler. I believe Erik Cortina is running the Wheeler in F Class so it shouldn't be hard to find info on it.

EC runs the Shehane. But his new cartridge is the 7/6.5 PRC-W…W is for Alex Wheeler. It is a 6.5 PRC sized up to the .284. NOT the new 7 PRC, however.
since Lapua stopped making the 284 brass, he had to find a new cartridge.

I spoke with Peterson and they said they might do a run in the first quarter of 23
Bob, remember that magazine length and throat geometry are of major importance. You may end up having to shoot the rifle as a single shot without some planning.
I would not put any case based on a 284 case on a short action, even with a Wyatt's mag box, WHEN the rifle was going to be used as a repeater for hunting.
Also, count the cost of the dies and delivery times. I have out smarted myself more than a few times.

Oh, my mistake. In a couple of his videos he refers to shooting his 284 Wheeler and I thought he shot his 1.3" group on video at 1000 with a 284 Wheeler. Maybe I'm wrong...
Regardless, IMHO a 284 Win or a variant of it is a viable option for the OP.
