Yes the secant ogive bullets are more "picky" than tangent ogive bullets in my experience.All my barrels are 8 twist. I think the 53 just has a more extreme shape that makes it picky.

The 107 and 183SMK’s do quite well.Have used Sierra 107 seconds for yrs. I do sort them n they shoot just fine.
Would the answer to the thread title question be "depends on how big the discount"?A shooting friend recently asked me this. I had an incident that happened to me a few years back after COVID. I bought some blemished 6mm varmint bullets and after seating a few I started getting some weird cartridge base to ogive measurements. After some serious head scratching and measuring a few bullets from that same lot I found the lot varied by as much as .040" in bullet base to ogive! Never would have thought about dimensions being a "blemish".
Sierra changed that. Now one machine, one operator and bullets stay in his lot. I caused a stir in 90s when I sent Rich Mahelich who worked at sierra a box of bullets with .020 variance in that one box. We had both shot 1k together. Rich invited me to tour their plant in Sedalia after they changed the process to one machine, one operator.Seconds can also come from machines being changed over from one bullet to another. The setup does create various ogive lengths, as it is very similar to adjusting a full-length sizing die. Point up on Spitzer-type bullets is another issue with some lead bleed out.
Years ago, at Sierra, they would segregate all bullets made on one machine as a lot#. The bean counters took over, and several machines were combined with a specific tolerance between all machines to save money. Dies wear, so different machines will have that as an issue also. Cheap labor becomes another issue, causing issues.
Good point. The Noslers I referred to in my post were listed as "blemished" and ordered through Nosler. As you said, could make a big difference.Probably depends on the source. For example, buying directly from Sierra would give me a good feeling they are just cosmetically blemished. Buying from a distributor, not so much.
