    I'm new to the 6 BR scene and have questions about Sorting Bullets. With my 50 BMG I shoot "Turned" solid brass projectiles, so I never have a need to sort BTO. I do, weight sort them into .2 gr groups ie: 799.1-799.2 (one group) 799.3-799.4 (a group) and so on. I realize that given the 799+ gr bullets weight, .1 gr or .5 gr really is small in relation to it's percentage of bullet weight.

    I'll be loading and shooting 107 gr SMK for my 6 BR, and as I began sorting by BTO there seems to be a varied range of measurements.

    How do you guys separate the differences? Do you separate them by .001" each"

    Do you separate by .1"-.2" groups? I hope I'm making sense, if not, please let me know. I'm trying to assure that depending on how I load my rounds, either jammed, or jumped, I'm looking for consistency, round to round.

    Lastly, Do you also weight sort , after sorting by BTO,

    Before,

    or no weight sorting?

    Question because I don't know. What tool(s) do you use to measure bearing surface on a bullet? Are you talking about diameter or length?

    I used to sort in .001” increments... but quit when I couldn’t see the difference on the target with unsorted bullets. The total variation in a lot will vary, but the max I ever recorded was .005” in Berger 105s.

    Good to know’ I’ve wondered if I’m going to far but all my range mates sort to a much higher degree so I figured I better get with the program or fall by the wayside.
    Plus I need all the help I can get...

    ogive to bt.
    I wind up with 5-6 lines of bullets out of 50.
    Berger is pretty consistent.
    60,65,70,75,80,85 so I guess to the hundredths. Maybe a straggler on each end.

    Youre going to need more bullets if you sort sierras

    SMK 107 will definitely shoot small especially when sorted. You could do yourself a favor and call Blue collar reloading they have Berger 108 target in stock for about $15 extra dollars for 500

    The least expensive 'accurate' tool that I am aware of is Holland's https://www.hollandguns.com/m7/H-GS-BC--hollands-gold-standard-bullet-comparator.html

    I had a shop make bushings for me that make it a bit easier to measure. While I didn't have to pay for the bushings, I could have purchsed a few Holland's for what the Mitutoyo and the stand cost.

    My Sinclair bullet sorter only goes .0005 resolutions and I don't feel the need for more. I segregate to .001. No weight sorting for me.

    Would either or both of you mind sharing what tools you use for bullet measuring.

    Thanks
