Realistic not fantasy. If we are talking years, not days or few weeks...
I have Long maintained that if I could ONLY (and I mean the '
Real World ONLY' - not the TV or movies 'only'..
have ONE Rifle / Cal.. it would be the .45-70...
Rationales: PLENTY of 'near-field Punch', and since I have 'proven to Myself' that the round definitely has Value out to 800 yds (or Further!
) even though, Sure - ya gotta 'lob the heck out of it', but.. Plenty of penetration-power, even that far out..
...Easier to reload a straight-wall, and a Nice, easy 'pill' to mold / shape.. Likely more 'forgiving' with a rougher / cruder 'DIY powder', as well.. (once all the 'Commercial' smokeless runs out, etc..) And, easier to work on / repair / less 'core-critical parts' (say, vs an AR-platform Whatever..) and nothing to lose or 'Additionally-break' / go-wrong (like Mags, etc..)
Sure, 'not a lot of Capacity' (vs, say, a 30 rd Mag, etc) but.. That's why ya Buy 2x - have one getting re-stuffed, Whilst Yer takin down [whatever].. And a Second rifle
Also serves as a 'backup unit'..
YMMV and all, but.. That's One Rifle I'd have No hesitation 'betting my Life on'..
