I've been asked to load a supply of ammunition for a co-worker's son and daughter in this caliber, sufficient for some significant rifle practice and hunting. He's tired of paying jacked up prices for inferior ammo, and was very pleased with the 30-06 ammo I loaded for him last year. I have no experience with this cartridge, but experience with similar (6.5x55, .300 Sav, .308). The son hunts heavy cover, and currently shoots 154 Hornady ammo. I was thinking of simply approximating this load as I have a large supply of the H154 Spire point already and I know it's a good performer on deer. The daughter is quite firearm savvy, but I still wants the recoil tamed slightly. The 154 Hornady ammo was a bit snappy for her. Was thinking of the Speer 145 BTSP stepped down a tad from maximum velocity, into the 2400-2500 fps range (per book quoted velocity, I know actual will likely be slightly less). I have available IMR 4064, IMR 4350, R15 and wouldn't be opposed to adding a medium speed powder with a good range of versatility in medium cartridges. I definately wish to stick with these 2 bullet options or something similarly inexpensive, or perhaps just the 145 Speer to keep cost down. I plan on putting up 500 rounds, and with new brass it's already a bit of sticker shock for my friend, but he wants to get the kids off on the right foot shooting wise with lots of practice and is willing to foot the bill. Pet loads anybody?
