I do believe in Captain Crunch.
Hi gang,
I know cast bullets are not often discussed in these parts, but I figured I would bring it up here before I ask this question over on castboolits.gunloads or artfulbullet. I am planning a build for the mid/end of 2025 and need to put in a barrel and possibly reamer order in a month or two so I can have it delivered in time for the build. I'm not sure what cartridge yet, so I figured I would ask all you with lots of experience and exposure to a bunch of obscure stuff.
I want to build a rifle that will shoot 30 cal cast bullets. Has to be 30 cal because 1) 30 cal is the optimal size where you can start designing your own custom molds. And 2) I seem to be the most proficient at casting 30 cal from a weight and dimensional stability perspective. Boolit weight is not a constraint. (legally you have to call it a boolit when it's a cast boolit) I'm not married to any specific boolit weight. I'd be good with either the 100s -130s grain wise or upto 180-200gr. I'll cast what ever works with a proven reamer design.
The rifle will be a range rifle, with a barrel profile around the medium Palma size (unless reamer notes or some other info pursuades me in a different direction). Twist and length will be determined by the needs of the reamer design. It will be shot of front rear and bags. 100 to 500 yards. 100 yards at first while I develop loads then probably 300 yards after that. 500 yards when I get the itch. I don't shoot matches, not even sure if there are CBA matches near me, but I'd like to get this rig as near to cast match precision as possible. What does cast match precision mean? I honestly don't know. In factory rifles and standard chambering, I'm able to achieve 1 moa at a hundred yards with the right boolit profile and tune. So I guess anything .5 moa and below at 300 yards would be nice if that's possible
My gut says look into 30br reamers that are cast specific, does anyone know of any or are there other cartridges that are suited for this type of thing. I think there was something like a shortened 308 win that was used a while back.
