    Started this same thread in 6br forum but haven’t got to many responses so thought I would try it here also.Looking for some load data using this bullet. I have searched aint there just isn’t much out there any I can find anyway....powders on hand are h4198,vv130,h322, and benchmark..any help would be greatly appreciated....Thought maybe backing off 10% from my 118gr bib load and starting???

    I shot a lot of these at 34.7 grains of H 4198, big difference in my rifle ( 17 Krieger ) VS BIB 118 10's , seems like the 30 BR can handle all the H 4198 you can put in it behind the 125 TNT's.

    Steve, can you elaborate on"big difference in my rifle vs BIB 118 10's".Sounds like where running pretty much same set up.Im also running 17 twist and bib 118 10's and my load is 34.5gr' of h4198 for the BIB's....
    Thanks

    The big difference I'm speaking to is the accuracy of the bullets. At up to 200 yds. the TNT's did score possible's on a one inch x ring but beyond that distance the BIB's clearly outperformed anything I shot prior. Where I shoot has a 2,3 and 400 yd. set up. We start at 2 then on and on to 400, 5 shots for score plus as many sighters as you want.
    I have a 330 x 0 chamber and use Randy Robinetts recommended 34.8 grains of H 4198 with His 118's.
    As to the TNT's I thought I could enhance their accuracy by weight sorting and B-O and base diameter segregating but it made no difference. I seated them at touch in Lapua brass that has been fired maybe 50 times or more with 34.7 grains of H 4198 and other powders. I used various primers and settled on the 450's as they shot better in my rifle than the Federals, no tumbling just outside neck cleaning with slight bump and resizing each loading. I managed to load 35 grains of H 4198 and the TNT's at times but less shot better. That's my story with my .30 Br. Hope any of it helps in any way, Steve

    Yeah I figured the tnt's wouldnt hold a light to the bib's but figured for the cost difference wouldnt hurt to have a load worked up for them.I dont plan on not using bib's anytime soon and have several still but you know how it is always tinkering lol....

    At 100 yds the 125 tnt's in my 30br shot one hole at 2 and 3 yds not very good
