fps for 220 gr '06 at 100yds?

I can't find any data on the ballistics for this bullet. Everything I look at tops out at 180 grains.
Where can I find this info?

Thanks

You'd have to know the starting speed to make any guesses...

Fastest muzzle velocity in both my Sierra and Hornady manuals for 220 gr bullets in 30-06 is 2500FPS, all at max loads.

On edit, to be clear, that is the max load, and only for some of the listed powders. Others don't get that fast, and max out 2200ish.

Yeah, my Lyman manual shows a 220gr jacketed RN anywhere from 2058 to 2583.

100 yards

My little ballistics program tells me that a Hornady 220 grain RNSP with a muzzle velocity of 2450 fps will be traveling at 2178 fps at 100 yards.
For a 2500 fps MV the 100 yd. V is 2225 fps.
Max MV in the Lyman load book #49 is an MV of 2583 fps whiche leaves 2302 fps at 100 yds.

Looking at the ballistics tables in the 1968 Shooters Bible, it shows a muzzle vel of 2410 fps, and a 100 yard vel of 2120 fps in both the Remington and Winchester data for the 220 gr '06 loads.

you need to know your ballistic coefficient, your muzzle velocity and your bullet weight to get that information. lots of reloading manuals go up to 220 grain in 30-06, my brother in law just loaded a bunch up using my hornady 8th edition.

Thank you guys for posting that info.
I was trying to determine whether or not the '06 was enough gun to "rule the world" so to speak. It is.

Before posting any comments, please keep in mind I was not searching for stopping power. I was only looking for sufficient energy to kill dangerous game. And yes, there are much better choices than the '06 to take to the Dark Continent. But that's not what I wanted to know.
So, to reiterate, thank you to those who posted.

I would never use bullets over 180 Gr. in the 30-06 ! If you want to kill stuff that requires a 220 Gr. bullet , get a .338 Win. Mag. and have enough velocity to get out a ways !

I did a little (operative word here) research and found that most shots taken at dangerous game are 80 yards or less.

You might enjoy this Sports Illustrated article. This gentelman has hunted successfully every North American big game species with the .30-06.

Can't tell you about the '06 w/220 grn RN bullets, but way back in its day the 30-40 Krag had the same 220 grn RN but a bit slower, right at 2000-2100 fps. MV,

It was known as a "stopper" and with FMJ had the penetration needed for dangerous game.

In B.O. Young's book "Alaska-Yukon Trophy's Won and Lost" (written in the early 20th century) Mr. Young talked of using the 30-40 Krag as a back up when hunting grizzlies or dispatching wounded grizzlies.

Its more then capable but its a round used when people hunted instead of just shooting animals.

To Add:

What I like about the Krag, (and the same goes for the '06 in the 200-220 grn bullets) is you can load cast bullets to the original velocity of the jacketed round, giving you a good hunting round.

In todays drought that's important, bullets and powder are hard to come by, yet for some reason 5744 powder seems to be available everywhere and its an excellent powder for cast bullets, allowing you to get the same velocities accurately.

So if you have primers you can get some low cost, good shooting.

I know we are suppose to be talking about the '06 but I think the 30-40 is one of the most under rated rounds out there.

Couldn't agree more!!





Not cast in the picture, but I do have the mold for 200 grain RN from Lee, as well as 1K gas checks and the sizing .309 sizing dies. I have a couple of pounds of Accurate 5744 and about 8K LR primers.

I will give a nod of respect to the 30-40 Krag because it has been there, even if it couldn't always do that.

The problem with using a 220 grn bullet in 30-06 is that most rifles won't stabilize them. A bullet that heavy in .30 cal really needs a 1 in 8 twist (or at least a 1 in 9).

According to the stability calculator at jbmballiistcs.com, a 1/12 twist barrel will stabilize a 220 grain Hornady roundnose at 1500 fps MV.

Yes, but a factory 30-06 round is going to have a MV significantly greater than that.

Everybody I've ever talked to that tried to shoot them gave up due to inaccuracy.

The bullet will be more stable at 30-06 velocity than at slower velocity.

I haven't shot a bunch of 200+ grain bullets out of the .30-06, but I took a black bear with a 200 grain Nosler Partition in Alaska in 2006. Bear was right at 200 yards and took him through both front shoulders like I was aiming for. I never had a problem with accuracy with that bullet and it shot a little less than 1" for my hunting load. I've shot a few 220 grain RN out of my .30-40 Krag and never had accuracy issues either shooting about 2" at 100 with iron sights.

I do agree that a .30-06 might have a problem stabilizing a heavy spitzer boat tail (SBT), VLD, or Mono metal bullet since the ability of a barrel to stabilize a bullet has nothing to do with weight but with the length of the bullet. The longer the bullet the faster the twist you need to stabilize it. Most hunting bullets of +200 grains aren't any of those three designs, most are semi-spitzer or round nose bullets with flat bases that make the overall length of the bullet about that of your average 180 grain SBT.

Thank you for that SI link Taylorce1. That was interesting to read.

Not sure about that. The Army went to the 1:10 in the Krag and Springfield because it does in fact stabilize the 220 RN bullet.

In fact that was the bullet used in Gen Hatchers example explaining twist, in his "Hatcher's Notebook".

Twist

Also not sure about that need for a faster than 1-10 twist.
For a while, I experimented with the Barnes 250 grain RNSP in .308" dia.. A very long gullet. I do not recall any accuracy problems with 1-10 barrels.

The 165 gr Barnes bullet is in every way superior to a 220 gr load in 30-06. Superior ballistics, penetration, and terminal performance. The late Greg Rodriguez wrote an article on the subject

Berger bullets says recommended twist rate for a 230 grain VLD boat tail is 1:10in. Bullet length is listed as 1.64'' which is probably the longest bullet you can use in 1:10in twist barrels.
