I voted for Barnes and Sierra but have loaded a lot of good bullets over the past 45 years. I am at a point now where I know what works for me, what I like and don't experiment any more for the most part.
In my varmint rifles it would be as follows:
In my 220 Swift, my favorite go to bullet is the Sierra #1390 55 gr HPBT.
In my 243 Win, my favorite go to bullet is the Barnes 80 gr TTSX.
In my 17 Rem, my favorite go to bullet is the Hornady 25 gr HP (not made any more but I have a lifetime supply).
In my 222 Rem, my favorite go to bullet is the Barnes 36 gr Varmint Grenade but also like the Nosler 40 gr Ballistic Tip.
For my 223, my favorite go to bullet is the Sierra #1390 55 gr HPBT.
In my 22WMR, my favorite go do bullet is the Winchester 40 gr HP (obviously don't load for this one but it is what I use).
