any point in lube groves when always PC'ing, have you ordered smooth sided?
when seeing all the pictures of peoples PC boolits there pretty much all standard lube grove designs, only seen a few with no lube groves. I get molds from accurate, my last one I knew id not be using regular lube ever, so I got his small tumble groves and it looks nice with PC and I could LLA if lazy. but is there any point to groves at all if only using PC.
maybe the multiple bearing surfaces acts like several gasket seals?
or provides displacement zone for rifling deformation?
or maybe lube groves are there so the edge of my scissors can fit in them to pick bullets out of the powder shake container without noticeable marks? ok maybe not that one
main reason I didn't want 1 large standard grove is when im looking through designs with PC in mind im thinking that's 10grs of mass missing for no reason. while not a lot, it means the lead either needs to make up that mass by taking up more powder room or outside dimensions for a given weight, so I consider it relevant if your trying to optimize.
also ive seen a large grove can fully obturate to a smooth side anyway when theres no lube to resist pressure. I cant imagine its more concentric than one who was smooth sided to begin with. so I wouldn't get one unless i needed it
do any of you order with lube grove delete? was there any noticeable positives or negatives? just trying to figure how I should order next time. the tumble groves seem like a good compromise, by the time its powdered and sized its just tiny notches, which looks nice and could tumble lube as backup plan, but im wondering if even that is pointless when its powder coated.
