FEDARM LLC AMMO SOLD IS NOT RANGE QUALITY FORT SMITH ARIZONA

I purchased 1000 rounds of "range grade" ammunition, I have now been to the range 3 times with it and iut of a 9 round magazine. I am lossing 2 to 3 bullets because they jamb, they dimensions are not there, some of the casings were mushroomed out and pressed back to the side of the bullet, I sent and email to them and the response was that I shouyld have read the description, the range grade ammo they send about 20 extra rounds per 1000 to make up for the "bad" ones, what happens if one of these blow up in the gun in my hand? I STRONGLY say do not purchase from this company, they did not want to do anything to make this transaction right or refund, and the price was about the smae as new ammo I have purchased from other companies.
