I am getting a new Texan but can't figure out which one to get. There's alot of conflicting info out there so maybe you guys can help me choose. I was going to get the 50 CF LSS but found out that it's a 510 and not compatible with my lyman 50 cal muzzle loader. Also bullet moulds are significantly more expensive than the 45. So that's what I will go with. Question #1 will the Lee dies for 4570 work OK with the barrel diameter of the Texan? Airforce claims it's a 457 but Tom Gaylord says it's actually a 458. Please let me know if you use the cheap Lee dies and if they are accurate. Also if you know of a cheap mould for casting balls please let me know. Question #2 what is the twist rate of the CF long I've heard 1in30 from Tom gaylord and 1in20 is the twist rate of the CF SS and carbine on airforce website. This is very confusing to me. Tom almost never gets things wrong so I'm assuming 1in30 was the older twist rate and now airforce is using a faster 1in20 to stabilize heavier bullets? OK last question. What size bullets would you recommend for the carbine and what size for the LSS? I am wondering if it's worth it to me to carry around that extra length. I have never hunted big game with a big bore but it seems to me that the carbine is probably making enough power for even very large game. Please help me decide guys. I'd especially really appreciate any advice from people that hunt big game and people that cast bullets for the 457. The cheapest way that works is the way I'd like to go. Thanks in advance dudes.
