I'm curious.
Now, I know not all rifles will shoot some bullets very well, no matter what ya try. Some guns just seem to shoot some very decent bullets poorly, and then shoot other bullets spectacularly. My Ruger M77 Stainless MKII is kinda that way. I badly wanted to shoot a Nosler Partition bullet in that rifle. Those projectiles enjoyed a good reputation as a controlled expansion hunting bullet that had good accuracy, and they're a "local to Oregon" (where I live) company. I could not get a decent group with any powder or charge with those chunks of lead & copper. Ditto for their Ballistic Tip bullets, or anything I tried frome Speer, Barnes, or Hornady. That rifle likes Sierra Pro Hunter 180 grainers for hunting, and groups them well at 100. I shot 2 elk with those bullets that were one shot kills, and many deer. For an "accuracy load", and for deer, I used to be able to shoot sub-1" groups with Sierra's 165 gn. Boattail bullets. It just didn't like Noslers or Hornadys, for some reasons. In the end, I felt better about shooting a bullet I felt I could place confidently and consistently over a premium bullet that I had doubts about where it might go..
I'm interested in what .30-30 bullets your lever guns seem to like, accuracy-wise, and maybe which ones do you feel really confident hunting with?
Added in EDIT: Mags called it right below here; I meant to write "3035" for the Hornady bullets I mentioned above, instead of "3305".
