I posted a question on reloading heavy bullets at reduced velocity for bush hunting and someone mentioned 300gr Winchester ammo from the 60's.

Someone gave me 2 boxes of these, very old ammo to try (said it to be 10years old). Took them to the range and what a surprise. For back ground - this was my first outing with my new .338wm Weatherby Vanguard, did not know what to expect as far as recoil or accuracy is concerned. After sighting the scope, took 3 shots at 100m - measured 24mm (0.94") then Since the area where I've booked a hunt was very dense, I tried them at 75m(82y), 3 shots in 8.8mm (0.34"). Fired both boxes and went back and bought the other 3 boxes he had left, for my trip. Shot a Impala ram at 171m. one shot kill. will include the pics. Bullet entered front of left shoulder and broke and exited the oposite shoulder. Very little meat damage and perfect performance for old ammo.

What would the negatives be for using old ammo, when it shoots perfect!!!????

Perfect shot placement will do it everytime. 10 year old factory ammo ( that has been properly stored )is no big deal. Use it and enjoy.

Shouldn't be any problem using 10 year old ammo. I have ammo that old and shoot it pretty regularly with no problems. There are a lot of people using ammo older than that without any problems. If you concerned about detrimental effects on your rifle, that won't be a problem.

The only problem with shooting it is that every time you pull the trigger you will be that much closer to being out of ammo!

Otherwise, blast away.

Should probably post it elsewhere, but what would you load today to duplicate the old 300gr Winchester Power points
