    I’ve been testing these for the past couple weeks and so far I’m loving them. They like to go a little faster than the 184s and I’m having to bump my powder 1-1.5 grains to get them there. I think a lot of guys will like these once they get their loads worked up.

    The fact they come pointed is amazing as well.

    Been testing at 100-600 and will start 1000yd testing tomorrow.

    As an example my 23 shot string last night had as SD of 6.5 with an avg. velocity of 2784

    Someone just asked and I forgot mention freebore. I’m running 220 and it’s working just fine even with deeper seating however I imagine there will be plenty of people who go 10-20 more on the freebore if they shoot the 190s predominately.

    Sorry John, what calibre, barrel and powder combo are you trying with them? Are you jumping these bullets? How much slower are they compared to the 184s at the same powder charge?

    Straight .284 on a 32” finished Brux barrel. It’s a hybrid so yeah, always jump and I’m still testing what jump they like but I’ve been anywhere from .009 to .033 for testing. I can’t tell you how much slower because I started testing a full grain higher knowing the weight was going to affect the load but like I said I had to go about 1.1 grains higher just to get the same velocity as the 184gr bullets with Reloader powders.

    I run the 184's just at/under 2800fps. You note that the 190's shot best running them faster than you ran 184's. What velocity were you running your 184's at in the same barrel and what brass/CBTO. I am just trying to get an idea on a starting point with the 190's. I ask for the CBTO to see how much your bullet base projects past the N/S junction so I can compare when I get a 'touch length'. TIA.

    I ran my 184s at 2770 in Peterson brass at 2.548 cbto which was a .015” jump.

    I’m at 2.555” at .015” OTL after 1600rds so we’re close on set up.

    Hmm, I suspect my Shehane reamer may be a little too short in the freebore to run these...

    Very easy to extend fb providing your smith has a neck reamer in the diameter you want..

    .188 - the plan is to fireform using 168s or 162s before moving over to 184s, at least that was the plan before the 190s were announced.

    that will be short. Even for the 184’s.
    .220 is minimum for the 184’s. Just get the throat reamed out

    It wot take long for Matt Paroz to lengthen the throat a slight amount to suit.

    Does he need a reamer of the same neck diameter for it to work properly Rod? My Shehane reamer has a .321 neck for Peterson brass so would Matt need a longer reamer with the same neck diameter?
