    PCed only works great in my .45-70. 405, 450 and 500 grain boolits. Some made for GCs some not. I donít see any difference.

    However, I canít hit a darn thing with my 6.5 x 55 mm without GCs, PC or not. Probably because it is a GC base. I figure with the bigger .45 cal. boolits, the difference in the diameter at the base doesnít matter much compared to the 6.5mm. Plus it gets pretty much filled in after PC and sizing. It is also going slower. Could the Micro Groove barrel make a difference?

    I have fallen in love w plain based bullets. That being said I bought a 50 beo. I shot 2 diff molds that I purchased. I custom noe mold from long time ago 400 gr design w a narrow drive band but large nose bearing surface powder coated of plain based design and a htc design 325 gr plain based. Loaded each to under 1600 fps. The 400 gr shot great!!!! The 325 shot terrible similar results as the op. My buddy said he had the 325 gr mold in gas check. Shot those and it was perfect. Itís all a new rule unto itself when messing w anything new in anything and to say it canít be done is straight foolishness. I figured the narrow drive band at the base would blow out no matter what and turned out to be my saving grace bullet rivaling the results of a gas checked bullet except I donít have to buy gas checks. A hard and fast rule is you generally have best results right off the bat w gas checks and you should gas check a bullet w a gas check shank but w that being said, one must discover that for theirself as Iíve seen plain base shoot as good as gas check and Iíve seen gas check tend to be the only way to use a piticular mold and thatís saying I tried the plain based version and then tried a mold w the gas check cut into the mold and used a gas check. Because the weather man says itís going to rain doesnít mean it will.

    PB checks perform great when you have a correctly cast and sized bullet to your bore's groove diameter, and load pressures to match your needs. Great accuracy, no leading with beverage cans. Hard to beat.
    First, apologies for reviving an old thread. Second, I have read the article on your site about this subject and am wondering if this is not the most perfect solution to my combo of a Lee 340 gr. PB in a micro groove 1895. The soda can economy is a nice bonus. My desire is to have one load at Trapdoor Springfield velocities and the micro groove barrel makes me a bit nervous. My other rifle, an H&R, isn't so picky.
