Thinking of trying some of The Bullet Factory's .224 55gr soft points, they are made using spent .22 shells for the jackets.
Do you think there would be any adverse affects of these on the bore of my 22-250, 222 or hornet? I realise i wouldnt be able to push em to hard out of the 250, but would be good enough for plinking and i reckon they should be pretty explosive.

Hey mate,
On the brinnel scale of hardness pure copper comes in as a 35, Gilding Metal (the stuff brass cases are made out of) rates as a 114. Obviously there will be slight variations between brands and batches etc, but even so it does show the difference in hardness. As a comparrison 304 stainless rates approx 1250. As to if it will damage your barrel im not really sure, but i would also consider possible cleaning difficulties, higher pressures etc. Ultimately it is still softer then your barrel but that doesnt mean it won't have any adverse effects. Hope that helps

I have used Turton bullets that are made from 22 shells in my 303-22 and 222 for years and not had a problem. If you shoot thousands of rounds you might see a difference. They are not made to the finest tolerance but are cheap.

i have also used these projectiles made from .22lr shell and they are cheap but effective pest ammo.
if you have concernes go onto AHN, look up the bullet factory, speak to jason( calls himself secantogive) he is the maker.
great bloke will tell you verything you need to know about his product including materials and manufacturing.
i use his other projectiles in .303 and have sampled his other offerings and cant fault them for the price, good simple projectiles that work.
