Ahhh missed it, thanks.OP stated at 50 yards.
And last time I checked CCI still makes 17m2 and 17HMR for Hornady. I'm n0t sure who makes Federal 17HMR.
I've read that CCI is the only company that actually makes 17 hmr ammo, so CCI, Hornady, Remington, Norma, Winchester, Federal, and Browning, are all made under contract by CCI. This is just internet hearsay, I have nothing to back that up.
That is my understanding also. I have shot CCI, Hornady, and Remington in two guns. The only difference I have seen is between bullet weights, One gun shoots 17 grain better than it does 20 grain bullets and it is the opposite with the other gun. I bought a couple of boxes of Winchester quite sometime ago but haven't shot any of it. If CCI made it I expect no difference, If Winchester made it and it is like their newer 22 LR ammo I expect it to not be too good.
I've also read that CCI manufactures winchester's 22lr 100 round plastic boxed ammunition, but bulk ammo that comes in the cardboard boxes is manufactured by wichester themselves. That seams logical because all the winchester 22 ammo in 100 round plastic trays that I have tried has shot great and has been 100% reliable, but the winchester bulk ammo is awful.
I got a really good deal on a couple cases of Winchester Supreme .17HMR 17 gr Tipped ammo years ago. It was awesome, if you like constant misfires. More recently tried some of their newer stuff, just as bad. I would not be at all surprised to find that CCI does make all the .17HMR ammo, other than Winchester. In my experience, CCI, Hornady, Federal and Remington have all been pretty comparable. While Winchester has been and still seems to be mediocre, at best. Hopefully I have learned my lesson and will resist any future “bargains” on Winchester rimfire ammo.That is my understanding also. I have shot CCI, Hornady, and Remington in two guns.

https://www.chuckhawks.com/ammo_roundup_17HMR.htmIt is true that CCI actually loads all of the .17 HMR ammunition for the CCI, Federal, Hornady, and Remington brands.
