hey fellas, i'm contemplating "what ifs" and wildcat cartridges on a rainy sunday morning , and was thinking about a general purpose cartridge for australia that would shoot projectiles in the 75-87gn range .
yes i know the 243 is more than capable and readily available , but i was thinking along the lines of moderate velocity , 2750 - 3000 fps , to preserve barrel life and keep barrel heat under control with sporter weight barrels . i remembered a article on the 223 case necked up to 25 cal , the 25-45 sharps . used 223 cases can be had for next to nothing for resizing, and this could be set up in handy light rifles with true short actions like the cz 527 , howa , rem7 ,ect. a rifle that would way close to 7 pounds or less with scope , be very pointy and compact, with decent "punch" and range . 7'62x39 rifles are sort of similar in concept i suppose , but the 25/223 hybrid would have better ballistics on light game and much better projectile choice
this post is intended as a discusion for a project rifle ,for those that love ballistics . i'm not trying to reinvent the wheel or replace the 243 as a "working" cartridge
i think some of you have played around with various wildcats like 6.5 grendal , 6mm br and such . i'm thinking the 25 sharps has some merit due to the case/neck relation of not being "overbore"
so, any opinions fellas
