I dont know if something like this has already been done or if there is a reason it has not. with the large case and fairly small 270 cal. bullet i would expect it to be an extremely fast round (maybe too fast). I would like to do this just for the challenge im not trying to get certain results out of this new cartridge. If anyone knows anything about designing new cartridges any help and knowledge would be appreciated. As of right now i Know very little about this subject and of the work that goes into doing this and now it is more of a hypothetical thing until I can get a sufficient amount of info.
have you given any thought as to the expense of doing something like this?
just to start off with will be that someone will have to build a custom reamer to make the chamber. more than likely a custom built action and definately a custom barrel.
then is going to be a custom set of dies to be made to reload the rounds. and then starting from scratch working up loads for which there isn't any loading data to start from.
just being realistic, but unless you have some extensive machining skills and gunsmithing skills and know quite a bit about working up wildcat loads and ballistics in general, i would have to say something like this is more for someone with a lot of experiance and not a novice.
what would be the purpose of the rifle and cartridge?
