    Over the last few weeks we have been testing the Gen 2 bullets out to and past subsonic ranges from a standard 338 Edge. In good conditions even after passing the sound barrier we were still able to hold 1 moa or better at distances out to 2318 yards, quite impressive (88 moa elevation by the way). We even tested at 2578 yards, I had to dial in all the elevation in the scope with a 20 moa rail (70 moa), turn the scope down to 11x to double the reticule caliberation and hold 40 moa for 110 moa total. I wasn't able to hold moa but it was pretty close at 1.2-1.3 moa, not bad for almost 1 1/2 miles. When was the last time your spotter call your come ups at "come up 1.83 degrees"? Windage was interesting at 2578 yards, 1 moa coriolis, 2.5 moa spin drift and 7.5 moa wind for a whopping total left correction of 24.5 feet. based on previous experience with 300 SMK's these are exceptional bullets for extreme long shooting.

    You can't test them much further than that! Awesome shooting, it sure looks like Berger got it right this time. Thanks for the update.

    I was there for one session of the 2318 tests. I even sent a few from my .338 LM as well. Spotting hit on the big screen is way cool!! The new found distances and consistancy of the Gen 2's will make you look into the 40 moa bases for sure. :)

    Brian Litz has brought back the old 308 bullet that would make it through the transition zone (with some improvements) and after I get back from my annual hunting trip I am going to buy a few boxes and see what I can do with them. Few people appreciate a good smooth transition zone passage.

    Very interesting. MOA-ish groups at those ranges is very impressive!

    I will soon test the transonic stability of 18 different .30 cal bullets through 2 .308 wins. Am trying to identify physical/mechanical traits that lead to or promote transonic and then subsonic flight. Really wanted some of those Berger OTMs (I believe this is the bullet BB is referring to) but they are out of stock everywhere I looked.

    How well does the Berger expand below say, 1800fps? I will also be testing the 208gr Amax down to around 1500fps impact velocity, as I've heard it opens up at that velocity, but wonder how the new "AMP" jackets affected this.

    Thats great news we carn't ask for better than that for bullet flight and accuracy from the 300gr berger hybrid the next big question is how does it expand !!at different ranges and at what velocity.lightbulb

    Shawn,

    Thanks for the update.

    Can you tell me if any of the shots you fired were not spotted or if any of them at all landed unexpectedly lower than the rest?

    90 % were spotted of the ones that wern't i believe the bullets slipped into a crack in the rock, I believe we would have spotted a low hit.

    On expansion search this section I did some testing at 1400 and 1800 fps impact velocities.

    Shawn,

    That's mind boggling to me.

    Just to help put it in perspective, you're talking about MOA at extreme long range.... but, how does that same rifle/load perform at 200-1000 yds?

    Thanks!

    My initial groups with the rifle at 100 yards were in the .230-.270" range. 800-1000 yard performance was sub 1/2 moa.

    Oliveralan,

    Please send an email to either Teresa Collins at teresa.collins@bergerbullets.com or to sales@bergerbullets.com. Provide either of them with your address and they will find the dealer nearest you that has inventory of the OTM. These bullets are in stock at our plant so those dealers who don't have them need only to order.

    Regards,
    Eric

    Shawn,

    I'm curious, what altitude above sea level are you shooting these tests? I've observed the bullets to be transonic stable out to 2400 in Wyoming last year, but that was at 6500 feet ASL. I've been wondering how low altitude they would survive. Denser air at low altitude is much harder on transonic stability than less dense air found higher up.

    Last week we shot these bullets to a mile, but they were only slowed to ~1200 fps in our conditions. Not too much transonic action there.

    Thanks for the report,
