Not knowing you familiarity with rimfires, I'll tell you that in my personal experience and opinion, only you will be able to find out what works best. If you put 10 separate 541s on the line, I'd be willing to bet that more than half will shoot a different brand and lot better than the rifle next to it.
I've had two frustrating experiences in te last few years. My Weatherby (Anschutz) shoots best with $15/box Federal. I put at least 10 different varieties through it, yet my Kimber SVT shoots CCI standard velocity almost as good as anything at 1/3rd the cost. You might get a lot of comments and find that you don't have the same luck as someone else.
Buy whatever variety you can find and have fun trying it all out.
Mattlewis,
I don't know civil82 nor have I ever spoken with him, but I fully understand and agree with his comments. Allow me to answer your last question from my perspective, experiences and learning from some top notched folks in the know who are experts in the field of Rimfire Ammunition.
As you may know, Rimfire Rifles, no matter the make or model, are extremely sensitive to the ammunition they are fed. Each rimfire rifle is also UNIQUE and no two rifles necessarily will like the same ammos, even if the same model,make or bear similarities in terms of action construction, etc, etc. Let me explain, I have two Savage MKII's (both bought to be given to two of my grandsons who are almost of age to start shooting) one a BV model and one a TR model. They have the same actions, but different barrels and different stocks. Shortly after buying these rifles, I started reading and studying rimfire ammos and consulted with a various folks who have extensive backgrounds in competition rifles and rimfire ammunitions, including Steven Boelter, the author of, "Rifleman's Guide to Rimfire Ammunition." In his book, Steve compares a high number of rimfire ammunition sold worldwide and tested that ammo in high quality rimfire rifles loaned to him by high quality and competition rifle manufacturers. After reading his books, that led me to conduct my own tests using the aforementioned rifles as well as conducting ammo testing with my Anschutz 64mpr that I made some slight additions to and use it in local Benchrest competitions, some of which I won or placed well.
From the extensive testing with the Savages (and I bought a great deal of the higher quality rimfire ammos available on the market some 3.5 yrs ago), I learned that some of the best ammo made is liked by one and disliked by the other. And even "LOTS" made a difference, meaning you could have s particular brand of high quality rimfire ammo, and just changing lot numbers made a difference in accuracy downrange. That is one of the reasons why folks who compete or are "serious" about their score, test and buy large amount of ammo having the same lot number and buy a great deal of the ammo (cases) when they find one their particular rifle shoots it's best with. But I found it curious and interesting that my Savage BV shot best using Federal Ultra Match UM22 ($17.44 a box) while my Savage TR shot almost as well using Wolf Match Extra ($6.95 a box). Of course my Anschutz demanded the Federal Ultra Match UM22, while disliking Eley Black ($12.30 a box) and Eley Tenex ($16.00 a box). Several of the other ammos sold then and even today, wouldn't shoot nearly as well, even many that are now made in Germany by Lapua, some of which I still use today for practicing and they run anywhere from $12 to $16 a box).
Bottom line of what I'm trying to relay, is don't depend on or try to make a correlation between any rifle make and a particular brand of rimfire ammo. You may want to "TEST" what other suggest, but until you try it in your particular rifle, you simply cannot rely completely on how other folks' rifles shoot using a specific brands of ammo. And one thing I should mention and recommend, there are lubed and non lubed rimfire ammos sold. After hours of testing and cleaning barrel whenever changing brands of ammos, my best results with any of my rifles was with lubed ammo, although I admit, I was trying to shoot not for group size, but for best accuracy, chasing the infamous one hole/5 shot group.
Hope that gives some ideas of what you may want to try doing with your particular rifle. If shooting 1/2" groups @ 50 yds satisfies your needs, then there are several less expensive ammos that might fit the bill. But if you want to shoot in the 1's, 2's 3's, it'll take better ammo to get there. And if you want to score well and even win shooting an ARA (American Rimfire Association) course of 2500 pts, where the points drop very quickly, then you must use quality ammos, but also ammo your rifle REALLY shoots well with. Good luck and have fun no matter which way you decide to go.
