They already have a 165 Accubond. The point to these ALRs is high BCs |

Where's the .338? I talked to Richard Mertz yesterday, and I'm thinking of a two-barrel MOA maximum. I think barrel #1 would be a .338 RCM, and barrel #2 would be a 6.5x47 Lapua. A 300gr .338 would be good medicine for a 16.5" Maximum!

Those are only the initial offerings. I'm sure .338, as well as 6mm/.243 will likely be added to the line in another year or two. New bullet designs always start out with a limited selection of the bullets they feel will be most popular at first until the mfg gets tooled up for full production capacity and their distributor inventory builds.

But if G1 is all you have, you'll be fine out to 600 with most high-power loads. Believe me, I was skeptical of this but ran a ton of different loads when unit testing my ballistic calculator app (and manually in JBM). The variation out to 600 might be 1". You'll see that difference just between reputable calculators using the exact same input. Ultimately, the only true test is actual range dope. You can tweak your calculator then so it can be used under other air densities. |

Sorry for my Amax post. I looked up the AMax BC. It appears this new hunting round has a better BC than the Amax target bullet.
I've been thinking about trying 208gr in my FNAR. It has a 1/10 twist, and really likes the 168gr. Then I could use the 208gr for hunting and longer range target.

G1 vs. G7 Ballistic Coefficients — Which Is Right for You? Drag Models — G7 is better than G1 for Long-Range Bullets G1 BCs, averaged between 1500 fps and 3000 fps: The reason the BC for the JLK is less is mostly because the meplat was significantly larger on the particular lot that I tested (0.075″ vs 0.059″; see attached drawings). For bullets like these, it’s much better to use the G7 standard. The following BCs are referenced to the G7 standard, and are constant for all speeds. G7 BCs: Many modern ballistics programs, including the free online JBM ballistics program, are able to use BCs referenced to G7 standards. When available, these BCs are more appropriate for long range bullets, according to Bryan. [Editor's NOTE: BCs are normally reported simply as an 0.XXX number. The lb/in² tag applies to all BCs, but is commonly left off for simplicity.] |

I read his book after a peaceful day right before bed.
I haven't read it for long long time. If I had to choose two books I could take with me that would be one of them. |

For just about any modern boattail bullet, G7 is a better number to work with. Especially if the it has a secant ogive.

All this is sort of academic for me.
I limit my hunting ranges to 400 yds and less and don't plan to shoot targets or varmints with bonded bullets beyond 400 yds. Almost all of my long range shooting is done with Hornady secant ogive projectiles namely the 123 gr 6.5 Amax, 105 gr .243 Amax & lately the .224 AMax.

Even out to moderate ranges, increased BC only helps a bonded hunting bullet.
Flatter trajectory, less wind drift, increased impact velocity/energy.
Win. Win. Win.

I have made the decision years ago that 5-7 percent increase in velocity, less than 10 percent increase energy, 1 inch or less trajectory, and less than 2 inches of windage is less important than accuracy, magazine function, and wound producing effects (penetration combined with expansion) on game animals at my self imposed 400 yd game shooting limit. Abilities to hold in hunting situations also are limitations.
I like Barnes tipped TX bullets and unfounded or not I have concerns about lead fragments in game meat. Targets up to 1000 are a different matter shooting from rests, bipods, tripods, hay bales and such. In this case ballistic "rocket science" does produce noticable results. I would expect that other major bullet makers will start using G7 data as the trend for long pointy long-range bullets and software development continues.

Noslers are real pretty what with all the colored tips but nearly every gun I own always shoots Sierras a little bit better, so my Noslers sit on the shelf.

Most ballistics calculators will accept either G1 or G7 BCs. Out to 600 yards it really doesn't matter (as long as you pick the matching model, e.g. G1 model with a G1 BC). In fact, getting air density input values (atmospheric pressure, temperature, altitude - if using corrected pressure) are more of a pain. But regardless of what models bullet makers make BCs available in I just wish they'd publish accurate numbers. I won't rule out a bullet with a lower BC if it has other performance characteristics I want. But I will shy away from brands that publish BS. Nothing like wasting a dozen rounds or so just to find out the BC was overstated by 5-10%.

These new Nosler Lond Range Accubonds should give those who are uncomfortable with the Berger VLDs "grenade" effect an option that may retain more weight and add some penetration for shots that are at a less than ideal angle.
I have had good luck personally with VLDs but I'm looking forward to trying these out.

Regarding the ballistic coefficent question there is an interesting publication from the Defense Technical Information Center entitled: Comparing Advertised Ballistic Coefficients with Independent Measurements.
I was not disapointed to find one of my favorite bullets as listed as having a 8% or so overated BC - that is the .264 Nosler 120 gr BT and that is it kills deer very well up to my self imposed 400 yd limit when shot out of a 6.5 - .308 (AKA .260 Rem). I have concerns regarding bullet time of flight between me and a game animal that is likely to move. For varmint shooting and and long range targets I generally shoot VMax's & AMax's. Would you believe that many select bullets on the basis of published ballistic coefficients? |
