Rufous: I own, shoot and Hunt small game and Varmints with two Remington 541-T's.
So I am interested in both accuracy and lethality in my ammo.
I use the wonderful Winchester 40 grain Power-Point hollow-points in BOTH my Remington 541-T's!
I see you come from the Vale, Oregon area and I used to varmint Hunt around there - so if your interests also include small game and Varmints then I highly recommend the Winchester 40 grain Power-Points.
You touch on a great point in todays ammo shortages - those seeking different 22 munitions to try are in a difficult situation!
Best of luck with your Remington 541-T. It is truly a FINE Rifle capable of excellent accuracy and possessing fine triggers and great looks and balance - only misgivings I have with them is the savage like chincey magazines.
Hold into the wind
