Using brass from a different rifle…

[Vern400]

Where you run into issues is if it was fired in a rifle with a larger diameter web area of the case. Thats where it’s going to stick if it is. You can push the headspace back where needed but unless your die is specifically cut to resize the base small enough, you’re never going to get rid of that issue.

You can also get some false pressure signs from this even if it does fit, guys will call them clickers.

If it’s for a plinker, give it a go and see what happens.

For a precision rifle, If your a new reloader, I would avoid the headache of dealing with brass fired in another chamber, I’d also not even mess with mixed lot brass. You’re just setting yourself up for some head scratchers down the road.

That's a good point. Even the small base dies that I recommended if he's using 223 won't work if you're fudging around trying to get fairly snug shoulder fit.
I totally forgot about that.

Thanks all.
I will defintely use the same headstamp for my loads. I have a few - hornady, lapua, adg and peterson. I will separate them, full size them and see how it goes.
I really don't want to buy new brass, I have probably damn near 1,000 pieces.

There is notable lot variance with same headstamp at times too. If you know you bought some boxes together or they are same lot, i'd keep them separated if possible. Might be a nothing burger but might be worth it.

You would also preferably want brass that was all fired through one other gun. Example would be if I had 200 pieces of brass fired from another barrel, the dimensions will be similar when sized, versus if your trying to size a bunch of brass from a bunch of different rifles, with varying headspace.

Powder and bullets are expensive, I’d much rather have a few hundred pieces of same lot Starline than range pickups.

I’d just put the Hornady in the recycle bucket

i honestly wouldn't put too much thought into matching the headstamp.
i literally open the necks on various 270wsm cases to use in my 300wsm.
I've ran Nosler, ADG, federal, Hornady, and whatever else i have sitting there and have noticed no difference in accuracy that would impede on real world hunting scenarios.
