Jason: I also shoot PC with my 22, but have been using Aguila 60gr. sss for both pigs and rams. It'll definitely take the pigs, and only occasionally ring the rams. You'll have to try and see if your 39 will be able to stabilize these bullets; my yellow boy has no problems, but I have seen them key hole with a fieldmaster, 1022 and an old Rem auto. Downsides to this ammo: stinks, and is dirty.
As for shooting 200 meter matches, your 30-30 will be just fine. Most of the competitors at the Nats last yr shoot this caliber. You need to go heavy, 170gr. I've seen the 150s ring rams very frequently. Other calibers I've seen are: 45-70, 38-55, 35 Rem, 44 mag, 357 mag. I've been told by people who have done a lot of experimenting with the calibre that the 357 is unreliable for the rams, even with the heavy bullets. Most of the shooters at our club are using the 44mag for both PC and rifle. Upside of this: just one gun for 2 matches. Downside, maybe: more recoil than necessary for PC. 300gr bullets, jacketed or plated, NOT cast lead, for 200 meter rams. Hornady xtp and Rainiers are popular choices. Your choice of powder: 296, H110, H4227, 2400, or something else in that burning range. This load is pretty stout. Thank heavens you'll just shoot 10 shots in a 40 shot match. For the turkeys, pigs and chicks, they use their 100 meter loads: 200, 240gr bullets and a fast powder. Titegroup seems the powder of choice here.
