Highjacking.... Sounds like you are a P. O. Ackley fan. I just got my first wildcat a week ago. It's a 243 Ackley built by Lester Bruno in Phoenix. He suggested loading up some precision fire form loads and just hunt/shoot them until the brass is formed. Said they would shoot about as good as the Ackley cases.
I did so. Bought 200 rounds of Lapua brass. FL sized, expanded, trimmed to length, took .001" thickness off the necks with a KM neck turner. Left the flash holes and primer pockets alone since they all uniform.
So, loaded up the 243 cases with 45.0 gr. of RL-22 (just had a lot of this on hand), 105 Berger VLD Hunting bullets, Federal GM210M primers. Seated the bullets out to touch the lands.
During the barrel break in and crony session at the range the rifle was grouping 5 shots at around .5 MOA by the time I was able to shoot 5 shot strings without cleaning. Average velocity was 2998 fps for the last 40 shots.
Not bad at all for a fire form load that does not have a whole lot to headspace on. I will be taking it with me to KS next week to dispatch some yotes and hole digging critters. Also taking steel silhouette and target stands for some long range fun. This will be a nice way to fire form the rest of the cases without wasting powder, primers, bullets, and barrel life.
Cant wait to see how this thing shoots with the Ackley loads and 300 fps more velocity. I had considered building a 6.5x284 but figured it was too close to my 7mm Mag. Wanted something for WT and smaller.
Cheers, sorry for the highjack..... Here's some pics:
