Looking at the recommendations made, they must be popular. Only two items of all of the recommendations made is even available from Natchez, Midway, Precision, or Powder Valley. CWT's 4064, and Swany's 100gr Sierra. You will encounter some prejudice against Sierra's bullets, and spitting the core is a common complaint. The opinion is usually endorsed by shooters that have never owned a single box of them in their lives. I inventory Sierra's in .224/.243/7mm/.308(30-30)/.358, along with Speer, Hornady and Nosler. They are all very fine bullets with +/- features. Sierra bullets are usually available, +, are often the most accurate, +, affordable, +, and if you push them past their design envelope will spit the core, -.
Adapting to reality, 4064 is an OK powder in the .243, and the .30-30 with a range of bullet weights, and 8lbs wouldn't be a bad call for a supply. I never run out of Sierra bullets for either cartridge. Midway has inventory on the 100gr Sierra's, and some pricier designs, good luck with .30-30 bullets if you don't want cast. I have about 500, 100gr Sierra Pro Hunters in .243, as they shoot well in almost any .243, and they are consistent performers on deer and antelope at any range a shot with a .243 is ethical. With supply as it now exists, I'd stretch my wallet a bit to have five or six boxes, based on 40+ years of using them in multiple .243's.
I know the thread is not about .30-30, but try to get a decent bullet on back order. For deer, any 150gr bullet from Speer, Sierra, or Hornady is gonna work. Over time, I have built a stock of all three, because they are all good. I like the Speer 170's, and Sierra 170's a lot. The Speer 130gr FP is a sleeper for smaller deer and probably antelope, in open country. By coincidence, I have never used the Hornady 170's. But grab a couple boxes of 150/170gr bullets. For the forseeable future, it's not stockpiling, is having something to shoot and hunt with. I'm not a Sierra/Speer sales or marketing guy, but the Speer/Sierra bullets for the .30-30 are real good candidates best in class. If you see, buy.
