41.0 grains perhaps. 410 grains of powder would equal – the most compressed load ever and that seems to be at about the speed suggested as 44 grains is about 2780 fps.

40 Grains seems about right, decimal points are tricky things. According to the IMR website, 40 grains of H322 with a 150 grain bullet should yield around 2,702 FPS. Note: This is a maximum load.
As stated by others 410 grains won’t fit and if it did, you would be eating a “Gun Sandwich” for lunch, at best.

Nice to see a bunch of reloaders chime in. In .308, I am partial to Varget and Sierra 155 grain palma. My last retail employment was at Huntington’s in Oroville, CA. As in Fred Huntington, founder of RCBS. How about some specs on Sam’s shootin’ iron?

Agree. I get my best 7.62 results with Varget, followed closely by N202. I’m shooting a gas gun, which likes medium speed powders and medium charges, so YRMV. Also, my rifle likes 168s – no matter what I do, I can’t get the cheaper 150s to shoot anywhere near as well as the 168s.
December 21, 2017 at 12:24 pm
Sam
Possibly due to the twist rate. My .30-06 likes 165gr Rem Core-Lokt bullets. 3 shots covered by a nickel at 100 yards. 150s opened it up to a quarter. 180s it takes a silver dollar. One of the big ones.

I hope that I can be permitted to go off-thread to mark a significant anniversary. 49 years ago, after an awful 1968 that had assassinations and center-city destroying riots, Apollo 8 launched this day for the first mission that went beyond Earth’s gravity. While orbiting the Moon on Christmas Eve, the three astronauts, Frank Borman, James Lovell & William Anders, read from the Book of Genesis about the creation of the Earth & Firmament! You can see & hear this broadcast from the NASA web site. https://www.nasa.gov/topics/history/features/apollo_8.html

A 168 BTSP with a high BC out of a M70 30-06 being pushed by Hodgson’s Superperformance Powder will give closer to 3000 fps. Flattens out the arc and extends usable kill range to the next area code.

I prefer a 168 Gr. Hornady Match, over 41.5 Gr of Varget… Half inch groups at 200 yards. That’s 1/4 MOA guys. Not too bad for a 20″ barrel Tikka.
December 21, 2017 at 11:52 am
Chris Muir
A Correction! According to the Hodgon reloading site, it shouldn’t exceed 40.0 grains. And at that loading from a 24″ barrel, the velocity should be 2,702 ft/s.
Hmmmm I know where the 2500 foot distant objective IS.
But where is that objective gonna’ be in about a second?
What’s gonna’ be in line, behind it?

Made a good living off guys and gals like y’all for 40 years. How often can you say that when you were doing and dealing with things, people, and philosophy that you love and would have done for fun and for free anyway?
While there were (and are) a few knucklehead know-it-alls (know-nothings) and dangerous mall-cop/sheepdog types, I gotta say the gunnie community is on the whole the most inclusive, caring, giving, group I ever had the pleasure to meet, deal with, and learn from (stop listening and learning and you become one of those knuckleheads I mentioned).
The antis, lefties, and elites don’t know what they’re missing.
Chris, as someone who who once changed foot pounds to feet per pound when describing a sniper rifle in a novel, you have my sympathy.
I love gun nerds…
But they will let you know when you miss.

Technical data to impress the readers is always a two edged sword.
For those well versed it will delight.
For those too serious and well versed it causes anguish.
And that doesn’t include artistic license like Arthur C. Clarke’s little fudge of moving the equator a few miles north to reach Sri Lanka.

Good to see you on board here, Holly.

Hey, Jim. Likewise, though I have a few friends named Jim, so while I think I know, I’m kind of guessing which one you are. Been a Chris fan for ages.
The foot-pounds error was the Serrated Edge collab with Misty Lackey. The error was all mine, though.

“And at that loading from a 24″ barrel, the velocity should be 2,702 ft/s.”
OK, but there’s no real “maths” for figuring that out. At best the internal ballistics maths would give a very rough estimate. Actual pressure and velocity are determined in testing, and vary from one barrel to another. The real maths comes in figuring your trajectory, which, given enough atmospheric data, can be very precise. See modernballistics.com
Someone in the field isn’t using maths, at least not in the sense that he’s doing the calculus in his head. He’s going on previous experience regarding bullet drop at various distances, for his rifle, with his load, under various conditions, relative to his sight’s zero. He’s using tables, either memorized or written down and kept with the rifle.
Determining the actual distance to the target is key in that situation, if it’s a long shot, so he may be wanting a laser rangefinder. A mil dot scope reticle, or other subtension based range finding system, will do also, if the size of the target is known, but a laser is quick and precise.

The ability to distance is the key. I’m passing my own event horizon in the fact that my rifles are getting better than me. It’s a heck of a thing to confront that which was second nature now takes concentration and outright thought. I can still do it but the quickness is abating. Luckily the mind is still sharp and I can OODA loop my way through a situation. As I was telling the special snowflake, don’t underestimate an old guy with an engineering degree.

I was trying to figure out the weight of the bullet that Sam and Zed we’re using. From my limitednon-existent knowledge, the weight of the bullet going downrange has some effect on terminal velocity. I know it has an effect on windage.
December 21, 2017 at 10:55 pm
Spin Drift
Bullets have Ballistic Coefficients (BC) that are used to determine trajectory. Shape, diameter and weight are all used in the calculation. As the saying goes, velocity peters out but BC carries all the way to the target.

No problems Chris. We reloaders see differences in various reloading manuals all the time. To the point that most use the manuals as a good starting point to match each load to the gun and sometimes exceed published limits if the rifle tolerates it. ..Ballistics can be interesting.

I think you meant ‘single base’.
A lot of us seem to have noticed that missing decimal. Good load aside from that.
I’m partial to a 168 grain Sierra Match King with 43.0 grains of 4895. There’s a lot to be said for the M2 AP load, too.
You would like the Privi match load then. 🙂
Has outperformed Fed GMM consistently, a nice surprise.
