    Question for Bryan Litz and Emil Praslick

    Here's my question: Is there an inherent ballistic advantage to going to a larger caliber? For example a 7mm 190 ATIP, .308 245 EOL, 338 300 hybrid, and .375 350 SMK all have fairly similar BC numbers in the mid to low .8 G1s and can all be pushed reasonably around 2900 fps. Why burn the extra...

    1200 Yard Setup - Advice

    If you want to optimize for hit probability the bergera with a 26" barrel in 6.5 prc is a good option of the rifles you mentioned. For a 1500 budget I'd shop the px for a factory action based 6.5 creed w/24"+ low mileage bartlien or similar barrel chambered by a competent smith. It won't be...

    Inherent advantage to larger calibers?

    The 375 allen express has some pretty decent numbers, but its no 37xc or 375 Cheytac.

    Inherent advantage to larger calibers?

    Thanks for the link. It would be nice if there was hard evidence that a larger caliber will do better through transonic. I got to image someone out there has done this kind of testing. On the first no-bs BC podcast, Litz mentioned that each bullet has a "fingerprint" on its actual drag curve, I...

    Inherent advantage to larger calibers?

    Tempting - but this thread is putting a dent in their market value for sure! My original plan after the 338ai was to skip the 375s and head straight to the 416. Yes, but... I think you can push these smaller bullets too hard, especially shooting an all day match. I would have done a 7-300...

    Inherent advantage to larger calibers?

    I'll start by saying I'm already pretty invested in a 338 improved project. I've been slow rolling it for the last couple years and just got my custom dies in. I also shoot 7 saum and 300 norma mag. Looking at the available bullets today, I'm not seeing a significant ballistic advantage...

    Range Report Testing the 7mm 190’s.

    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...

    Range Report Testing the 7mm 190’s.

    Nice to hear on the ATIP BC. I believe the advertised BC is for 200 yards. Based on their published bc data for other bullets, a drop in BC is to be expected at long range. https://www.hornady.com/support/ballistic-coefficient It will be nice when the litz values get published for this and...

    Range Report Berger has a new 7mm bullet

    I’ll be sending some at ~1300 yds on Saturday so we’ll see

    308 win for 1 mile shot

    @MontanaMarine did a lot of work with 208s in a 12 twist. https://www.snipershide.com/shooting/threads/308-win-208-amax-rl17.14159/ I had no issues stabilizing 208s in my 11.25 308.

    308 win for 1 mile shot

    That may seem like a big plate, but at 1500yds its around 2.3 moa wide and only 1.5 moa tall - so close to the average precision rifle match target size. Toss in the increased challenges of wind reading and vertical spread at that distance and its not a chip shot for most of us mere mortals.

    Range Report Berger has a new 7mm bullet

    Thanks, I see that now, not sure why Midway has had me on back-order since November.

    308 win for 1 mile shot

    I'm fairly sure @sstacllc has used a similar 308 175 RDF load as mine to proof the NF ELR Steel Challenge targets. Not sure what his hit ratio was but I don't think he wasted a lot of ammo doing it. For sure the energy is weak, but out to 1200yds - especially in higher elevation - I don't think...

    Range Report Berger has a new 7mm bullet

    In my testing (done at 1284 yds), The 183s shoot fine but are not as consistent as the 184s when pointed. The 185 rdfs seem to be a step down in BC from the rest of these. I did an initial test a few months back and got very promising results with the 190lrht, but only one data point (8 rounds...

    308 win for 1 mile shot

    I'm dredging up my own Necropost because I though it would be fun to revisit the 308 at a mile six and a half years later. This past year I did manage to get consecutive hits on an IPSC at 1715yds (w/magnetospeed t1000 target indicator). I don't remember how many, but it was more than 2 but...

    Is HBN worth the effort or is it snake oil?

    But we are looking to improve the cold bore, which means reducing it's distance from the center of the group. That distance still requires statistical analysis to verify reduction, as does just about anything we try to improve in shooting. Yes you can make reasonable observations on very large...

    Is HBN worth the effort or is it snake oil?

    One group won't tell you very much, you need to shoot a statistically relevant sample size for the improvement you are trying to measure. https://www.autotrickler.com/blog/practical-statistics-for-shooters

    Is HBN worth the effort or is it snake oil?

    I've stopped looking at SDs much, and focus more on actual vertical spread past 1K as there are more factors there (e.g., BC variance), but last work I did with 6xc and a labradar was 26 shots and SD of 4.8.

    Is HBN worth the effort or is it snake oil?

    yes, I’ve noticed my cold bore shots going into the group, but more than that the velocity is consistent, which for the match I shoot (NF ELR) is critical.
