    This weekend's long range report

    Good times this weekend. Conditions were nearly perfect for some 1K shooting Saturday- overcast, the first day in 27 consecutive it didn't break 100 degrees & little to no wind.

    Rifle is one of my builds- RRA lower, Satern 20" (19.5 actually, I had it cut & threaded to 5/8 x 24), Mega side charging billet upper, Gunwerks break, CTR stock, JP rail, Geissele High Speed trigger, Zeiss Conquest 4.5x14 - 50, Larue 10 MOA canted mount.

    I've developed 2 good loads so far, one for long range target shooting & one for varmint hunting.

    Long range load- 123SMKs, 28.6g 2808, Alexander brass, 2.260 COL, CCI 450. 2550 FPS

    Varmint load- 100 NBT, 29g 2808, IMI 7.62x39 fire formed brass, 2.260 COL, Remington 9 1/2. 2710 FPS.

    Test firing.

    No pics of this weekend but I got a 3 round group of 3.5" @ 500 yds. I also slung a few out to 750. They did OK but these little bullets really run out of gas and get bullied by the wind. I could probably get a bit more velocity out of them if I were using Grendel brass but these are primarily field loads. I would rather use cheaper brass and not worry so much about finding my high dollar casings in the grass.

    Almost forgot- one of my major goals for this weekend was to figure out the data adjustments & correction factors I needed to get my ballistic calculator working accurately. I'm using the "Shooter" App for android. With some careful data collection and help from a friend I got it dialed in. I was able to accurately calculate my adjustments for both loads at various distances out to 1K with great results.

    Now I just need a place I can shoot unknown distance targets at extended ranges...

          Excellent post with great pics. You indicate that there are five shots measuring over 6" on the 19" steel plate. What are the other marks on the plate. Great shooting. Maybe I'll get frisky and try my 16" further than 600yds.

              Hits from other people. I was at a public range.

                I'm impressed! How is 14x at 1000? It that enough scope? You obviously got on target, but were you comfortable with that magnification, or could you have used more glass? I've never shot at that range, so I'm curious.

                Tiger Valley by chance?

                  For me, 14x is plenty at 1000yds. 10x is plenty at 1000yds, especially if you have glass with great resolution and a clear, crisp reticle with fine intersecting crosshairs. I also have 20/15 vision, so I have an edge in that regard. As long as you can clearly index your sight picture at the center of your target, settle the gun well, and maintain that sight picture throughout the shot(thanks Gene), you're good-aside from your doping of course.

                    14x is plenty with this quality of glass. I have no problem bisecting the target and getting consistent POAs (as long as my head is in the game). This is why I like the Zeiss conquest line of scopes so much. Superb glass (equal to or better than Nightforce, Leupold, IOR, even USO & S&B in my opinion) at a reasonable price. They aren't necessarily as rugged as some of the aforementioned brands but I don't intend to abuse this rig too much.

                      Thanks for the info on glass. Now that I'm well into presbyopia, I have a much greater appreciation for optics that offer the ability to resolve my target.

                      I did not know BotW had distances out to 1000. That's good to know, particularly because BotW is much closer to me than TV.

                        It's a great range. You should come check it out. I cast all the bench tops out of concrete for them. They are good and sturdy.

                          What was the reasoning of using CCI450 on 123 and remington 7 1/2 on varmant loads? They both cross reference the same?

                            Those are Rem 9 1/2- large rifle. 7.62 x 39 uses LR.

                              Hey txgunner00,
                              How does your brass look with that hot of a load. At 65f and 28.4g of 8208 XBR I was beating the crap out of AA/Lapua brass and getting deep extractor marks in the brass. I have now backed down to 28.1g 8208 XBR.

                              Nice shooting! I have only gone out to 800 with mine.

                              Until that day,
                              Darkop
