    5BA335D8-7B22-4F6E-8912-8D24C93E1EF7.jpeg I got some of the Lehigh defense 6.5mm 121 grain copper solid today. I have some in the tumbler getting hex coated as I type this. I hope to send these way out there.
    .536 g1
    I’m hoping with hex to get them to 3100-3200 fps.

    147 ELD
    121 Lehigh
    140 ELD
    140 RDF

    I really like those bullets!!
    $$$$
    One to ponder something interesting?
    Run both of those bullets thru a twist calculator at sea level.
    But both companies claim and it’s proven they are stabile in a 8 twist. BCs are checked with a 8 twist, I believe..

    Right now, I'm running a 1:7.25" twist in a 22" barrel with a suppressor. 3200+ fps at sea level. The Berger Calculator agrees although I think the math being used is slightly stilted...:mad:

    Yea, I was baffled. My question is, if BCs are calculated with the slight stability decrease in mind with a 8 twist, then what are the BCs when running at 1.5sg and above? Or, is the calculator not taking in account the difference in “balance” that a mono would have because the lead core is missing.
    And in fact they are running at 1.5 Sg or above?
    My reasoning is everybody who’s run the Warner’s in a 8 twist, are saying the BC is true or slightly low.

    Frank tested the Warners and had .670 at 3100fps in a 22" creed running 3100+. Also he has a DA advantage out in Co with that altitude. If your using a longer tube cfe223 should get you 3200 with varget there also. 4166 was the powder used with good sd and 3100+ with accuracy. Frank is not a guy who fiddles with the load so if you play with seating some you should be able to get all of these powders shooting well at very good speeds. I think he said that the doppler numbers were established with a 2900fps velocity. If you have some 2000 mr that would also be a great powder for speed and accuracy. I saw some speed using 120 smk's 2990 in a 24" without pressue in norma brass. Only did a ladder and it was below 30 degrees when I tried it.

    Thanks for the data.
    I watched Franks vid on the Warner’s. I read he was running a 1-8.5 twist at 4500 ft. altitude. I didn’t run his twist and elevation thru a calculator, but he corrected to a .69 g1. That is a awesome bullet. I just wish they could get them down to 30-50 cents a bullet.

    I have about 500 left. I tried to find some disparity between individual bullets but I admitted to failure after the first 50 or so...:rolleyes:

    That’s the same with these Lehigh bullets. Lathed turned is definitely consistent. It’s probably why CEB dominates the two mile match.

    Hornady 143-147 grain seating stem is a no go with the Lehigh.
