hello everyone.
i am from new zealand and have recently purhased a cva scout in 44 mag. have a bit of a plan for this rifle which involves cutting the barrel down to 15-16" and having a suppressor fitted for use with subsonic rounds, the other use being as a pack rifle firing supersonic ammo without the suppressor on for an ultra portable package.
i have bought a box of hornady 265gr ftx projectiles as i was planning to ream to 445 supermag for a bit more reach but i am really struggling to find brass here. so my options appear to be either to leave it as a 44 mag or go for 444 marlin with more readily available brass. i am worried the marlin may be a bit too much for what might end up being a very lightweight wee rifle, and have unacceptable muzzle blast with the short barrel? also it would make subsonic loading more difficult compared to a standard 44 mag.
so what i would like to know is whether there is any way to use a standard 44 mag case to get the 265 up to any kind of decent velocity? i would ideally like to be able to shoot medium sized deer out to around 150-180 yards. being a single shot can i seat them right out to allow a bit more powder capacity? or would things just get dangerous?
any help would be greatly appreciated, the 445 really did sound ideal but i do not to be stuck without brass!
thanks.
adam.
