Re: 5.7x28 bolt rifle
I've reloaded them a lot, they stretch like crazy but other than that they are reasonable. I wouldn't recommend loading them hot, I had a piece of brass separate in the chamber of my 5-7 pistol leaving the neck and shoulder in the gun, not so fun. But I got it out and all is well. I would recommend staying in the mid range of what the books or powder companies list for loads.
