    Well I just ordered a big pile of bullets.
    In the end I went with the Berger 190’s.

    Consistent, a bit cheaper and my current barrel just seems to like them.

    The ATip’s BC is better but honestly I’m a bit gun shy locking myself into a Hornandy bullet at the moment.

    I got a good deal on 480 197 smk so gonna burn them up and see how they perform before testing more. What is the load you are using for the 190 bergers? Powder velocity charge weight ect? Really liking the saum

    Well I tested them at 2850 with about 60 grains of R26.
    Now that I’ve decided on a bullet I’m gonna see if I can get them faster, I do believe my barrel is starting to slow down a bit though.

    Initially shot them at mag length and now I’m at a single load length and obviously that has an impact so I’m gonna do a short velocity test above my current load.
    I’ll know more Friday.

    Awesome. I have long action i was thinking setting bullets out way long and using h1000 with 28inch barrel and see what would happen

    If they were closer in price would you still pick the Berger's or would you go A-Tip?

    @Steel head just man up and go 28 Sherman Magnum. throw those 190s at 3300
    Meh.
    7 saum is a nice balance of economy and performance.
    100-2000 yards is totally doable in my shooting area.

    The extra speed ain’t gonna make it a 2500 yard cartridge where I live because spotting can be difficult with the often wet rocks and dirt.

    260
    7SAUM
    and hopefully someday 37XC or something similar
    All bases available to me would be covered

    Have you compared the 190s to the 195s? I was surprised to see the 190 has a 0.030” longer bearing surface.

    Any updates on the atips? You ever find any recovered bullets? Wondering if they’d be a good hunting bullet? Did you ever test the 197 smk?

    190 Atips got a hit on my second shot at 1760. I’ve been really happy with these things so far except for the price!

    Is your chamber throated for the 190, or SAAMI? What barrel length?

    I threw .422 in my Kestrel and was about .2 low which is what about 12.5” at a mile. My cold bore shot was just under the plate came up one tenth and held the same spot and got that impact.
    It’s chambered for the 180 ELDM’s that’s what I mainly shoot they have been darn good just thought I would try a box of the Atips to keep for longer distances.

    Here's my testing from Saturday.

    I think the 190LRHT, 190ATIP, and 183SMK are all very excellent bullets and viable choices. From a statistical perspective, their performance is pretty much identical at the distance I test (1284 yards on paper). My performance measurement is vertical standard deviation.

    View attachment 7303492View attachment 7303493

    I will likely go with the 190LRHT as it looks like a safe bet. I had good results before with the 184F-open Hybrids, but now with the 190s there is no need to point them myself. The A-TIP is a clear leader in BC, but its interesting to note that the 183 SMK is not very far behind on drops when put in front of the same powder charge. Also, on the LRHT I sorted by length and SMK was sorted by weight and length. I did not sort the ATIPs, so I may be leaving a bit on the table with them - but for their cost and marketing - I shouldn't have to sort them.

    My velocity numbers are derived from BC. I found myself playing around too much with the labradar and magnetospeed to get inconsistent results - so I test on paper as the bullet tells the truth.

    I had one questionable shot that went into either of the 183SMK groups, the rest of the numbers I'm fairly confident in - although I'll need to re-check my zero with each of these bullets next time I go out to confirm drops.

    *Load data here is over max book loads for 7 SAUM, I use TBN coating and have a custom throat to allow an OAL up to 3.2 - do not attempt to use these loads, I don't take any responsibility for your reloading practices - and would you really trust a guy that shoots MOA?*

    Are you on a long action? Or just single feed? Thanks

    Yes, they’ve been consistent with different lots and not a single one has blown up.
    I did have a few 190 a tips pop but at a much lower rate than the 180 ELD

    Hi, could you please tell me what barrel, twist and BC you are using? I'm plagued with bullet blow-up problems in the 7mm Practical. My plan is to go with 7mm Blaser and a Bartlein barrel 1-7.7" 5R. Got 500pc 190 A-TIP but I'm scared to have the same results as with the 180 ELD-M... Reading your posts it seems that Berger 190 LRHT is a safer bet? But the A-TIP BC is so tempting :))

    Another good option for that practical i have a 7mm-300 win mag barrel on its way and made it around 197 smk. Had great luck with them just a heads up. I think we all had the dreaded 180 eldm blow ups!!!

    Brux 1-8.
    I’m using the Applied ballistics CDM but the BC on the box is GTG with very minor tweaks as needed.

    The Berger 190 LRHT is fantastic, and I can count on it getting to it’s destination.

    If you have the horsepower the 197 looks like a good option as well.

    Who did your brux 7mm saum barrel for your nucleus?

    Thank you for info, not familiar with Brux barrels. What kind of rifling are they using?
    5R? something similar?
    Had a lilja 1-8” that blew up the 197 SMK :-(
    But hoping the Bartlein 1-7.7” 5R Will treat bullets better 🙏

    How fast you running the 197?
