Home Forums Hunting & Shooting Custom Rifles & Wildcats .300 H&H Magnum Wildcat- 300 H&H "Super"

300 Coulter sounds pretty good, that is what I would do and might even have the barrel stampes as such. Neck size, use 300WBY data, a tad bit backed off until loads proven and hunt! With 7828SSC, you should be able to get to 3200fps with 180gr TTSX's and similar. Add powder till you see that number or see obvisous pressure signs ( I predict you wont get to any signs of pressure first) or see 3200 on the Chrony and call it good. Nothing that load won't do that one should attempt with a 30 cal anything. Same/same with the 168TTSX running 3300. I have a shorter version of a similar era wildcat called at the time a 30 Belted Newton. Because of the slow burn rate and long pressure curve 7828SSC is your friend.
