Ive had my grendel for about 5 years. Due to getting tired of the endless search for hunting ammo ive started to reload for it. Ive got everything i need to at least start but have some questions. I have 123 gr sst projectiles, h335 powder, hornady brass once fired. I havent been able to source any cci 41 or cci 450 but i did pick up 300 winchester wsr. Will these be fine to load with for and AR? Barrel is 18 bca. I know not the best barrel but mine did actually shoot lights out with sst, hornady black and federal fusion

They will be just fine. But only your barrel know what its gonna like!!
I have been able to make a few Grendel's shoot with H335. Tho I like Auto comp and 2520 better.
As for bullets the sst has always shot well. I find it a tough fragile even @ Grendel velocities. Same for the Gold Dot if you push it hard. But stay 2400 ish and both do as well as any. Coarse if your only shooting steel and paper its zero worries.
Good luck

Welcome to the Horde!
Recommend 8208, 2520, BLC2, and Win 748 for powders in that order. (But not all in the same case)

Midway has routinely had CCI 41 primers. Just have to keep checking.

IMO nothing wrong with BCA barrels. I have a 24" SS that shoots 90 gr TNTs < .75" @100 yards.

Under,
Any small rifle primer will be fine, however something with a thick (hard) cup will lessen the chance of slam-fire with the AR's floating firing pin. That said, slam-fires are as rare as hen's teeth.
