Thinking about building another rifle and I've got a few unique specs so I thought I'd throw it out here for everyone to weigh in with thier 2 cents. On gunbroker right now there are a couple of CZ 550 actions for sale. It looks to me like they come complete with mag box bottom metal , trigger, and screws. Now I'm a big CZ fan and I already have a 550 safari in 458 Lott and I love it. I'm planning to do a safari in the next few years hopefully. Buffalo and Kudu and hopefully some other plains game if I can fund it..so I've got the buffalo covered with the 458 but I was thinking about grabbing one of these actions and building a hot rod plains game/elk/brown bear type rifle. The interesting thing is these are 416 rigby actions so that means they have a .585 bolt face, so we're in the 338 lapua, 30/378 weatherby, 30/338 lapua realm. I'm a big fan of the lapua, but with the heavy 30 cal bullets available now something in the 30 cal could be very tempting. The CZ action allows for a mag capacity of 4 or 5 I believe with these diameter rounds plus CRF which is a bonus and I love the CZ triggers so no need to change any of that. I've seen the CZ Kevlar stocks for sale in the $350 range and McMillan also makes one for this action which only leaves to to chose a caliber and purchase a barrel and find a Smith that works on CZ rifles. If you all have any suggestions in that arena please let me know. Also, just for curiosity sake I'm going to post this same thread on longrangehunting.com and we can compare the different suggestions and perhaps the different ideas on what each group feels would be the best use of these components. Let me know what you think!
