I do that for handguns alot. And my varmit rifles. I have found two factory loads that will shoot within a half inch of my handload. Good for when you prairie dog shootin and don't want to use your good handloads.

I traded with a fellow a few years ago for a 7 mag browning,he said it shot one hole groups with factory bullets,didn't believe him untill I tried them.
Bought 270 sps rem last year a fellow at the range gave me 7 of the 130 fusions to try shot a 3-shot group in one small hole,still have 4 left.
When the rem 260 came out I had to get a box of factory to get the cases for reloading,danged if they didn't shoot one hole groups in the rem mtn 260.
But I had rather shoot my reloads thats a big part of shooting.

Trieda lotof the expensive new stuff with the catchy names. It is not as accurate as my handloads. Some of it is not very accurate at all.

I hardly ever shoot factory Ammo, there are just to many lots of ammo, thats why I have always handloaded my ammo, the ammo I shoot this year will be the same next year and until the 8# of powder I have is shot up on my favorites I will buy 2 or 3 8# kegs of powder with the same lot numbers.
