I am planning to use my stock Jungle Carbine for a truck gun this season while hunting moose and deer for nostalgic reasons primarily. I want to use a factory spitzer 180 grain factory ammo. Is there any make that stands out for accuracy and performance? Federal has loads with 180 Federal bullets, 180 Speer Hot Core, and 180 Sierra's. Winchester has the 180 Power Point. I want to use 180's for penetration in case I see a moose but want the bullets to expand on deer also. Any comments would be helpful. Thanks

I've never used any that you listed except the Power Point, and they work fine.

Actually, my favourite 303 factory load was the old Remington round nose 215 gr. Best moose 303 load ever, IMHO. - Dan

The standby for years was Imperial, I used them along with thousands of other Canadians, good stuff.
