Had a successful Father's day with my youngest son Eric (15) at the range this afternoon. He shot his .270 and my Springfield V16 Long Slide in .45 Super. He even took 2 shots with the 375 H&H using factory loads. I had good results with both the 350g Woodleigh PPs and 250g Swift A-Frames

CZ 550 Safari Classic in 375 H&H 25" barrel. Rem Brass, CCI Large Rifle Magnum Primers and Lee Factory crimp die used for all loads.

350g Woodleigh PP 68g H4350 3.60" OAL (.100 freebore) 2260 fps 1.25" 3 shot groups 100 yards
350g Woodleigh PP 70g H4350 3.60" OAL (.100 freebore) 2310 fps 0.75" 3 shot groups 100 yards
350g Woodleigh PP 72g H4350 3.60" OAL (.100 freebore) 2360 fps 0.65" 3 shot groups 100 yards

All of these loads fed and extracted flawlessly, recoil at 72g H4350 was stouter than 300g factory loads but still very mild. 72g of H4350 will be my load for the 350g Woodleigh PPs, it may be too hot for your rifle so start up slowly.

Note: 72g of H4350 is MAX in my reloading manuals and proved so in my testing! I shot two more groups at 73, and 74g and this is NOT RECOMMENDED. Velocities exceeded 2500 fps, recoil got increasingly stout, extraction began to get a little sticky and the beginning of extractor marks appeared on the cases. I threw those cases away.

250g Swift A-Frame 69g IMR 4320 3.54" OAL (.50 freebore) 2710 fps 1.10" 3 shot groups 100 yards
250g Swift A-Frame 71g IMR 4320 3.54" OAL (.50 freebore) 2860 fps 0.90" 3 shot groups 100 yards
250g Swift A-Frame 73g IMR 4320 3.54" OAL (.50 freebore) 2910 fps 0.50" 3 shot groups 100 yards

All of these loads fed and extracted flawlessly. Recoil was very mild compared with 300g factory loads. The last 250g Swift A-Frame load with 73g IMR 4320 which is the stated MAX in the Swift reloading manual will be my Colorado elk, deer, bear hunting load.

Thanks for all of the help on this board. Hope this data helps someone else.

Regards,
Chuck
