Just curious about actual chrono's velocities f0lks are getting with their 338-06s

Can you provide bullet, powder & charge, and bbl length.

Especially looking for

200

210

225

grain loads...

Thanks

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.




What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

Hi Mike,

I can post the only load that I've worked up to date:

The gun is a pre-64 Winchester with a 24" #3 contour Pac-Nor Match grade chrome moly barrel in an Acrabond stock.

I prepare the brass with a K M primer pocket correcting tool and a K M Pro flash hole uniformer on all my brass prior to loading the first time and trim to 2.484.

Weatherby 338-06 brass (I have A-Square brass too, but it's my understanding that both Weatherby and A-Square brass is made by Norma)
Winchester WLR primer
62 grains Ramshot Big Game powder
Barnes 210 grain TSX

Chronographed velocities are always in the 2815 - 2820 fps range. This is the most accurate load that I found while working up this combination of components.


Regards,
Brian


Meet "Beauty" - 66 cal., 417 grn patched roundball over 170 grns FFg = ~1950 fps of pure fun!

Hey Mike, I pretty much only shoot the 210grNP & 200gr Speer. From my 22.5" bbl.
63gr H4350/cciBR2/Norma 06 cases/3.295 OAL = 2750fps+/-
54gr (current prod) RL15 yields 2700fps+/-
I pretty much have given up on the 225gr bullets, accuracy just sucks. I can squeeze another 25fps in both the above loads by adding 1/2gr under the 200gr Speer. Groups start to open up if I push them faster. I have yet to want/need more bullet than the 210grNP. beer

Fred,

Can you clarify which load goes with which bullet?

Mike, I have a 24" barrel on mine. I use Nosler 30-06 brass, CCI 200 primers.
200 gr Accubond- 2850 w/ RL15 55gr
210 gr Partition 2750 w/ H4350 61 gr
225 gr SST 2700 w/ Big Game 59gr

Remember to reduce all loads as these are near MAX in my rifle and may be over in yours.

So it would appear an honest 2700+ w/a 210 is capable from a say 23" bbl

Thats easy, Two 4 barrels instead on one, and headers! also added a 411 rear end to it.....

made all the difference in the world... banana

BOOM

Actually you must be referring to that 2250 fps duplicating the old 33 Winchester, aren't ya?

As a forum member told me a couple of seasons ago, I must be using Pixie Dust in my reload technique...hey whatever works...

sacrificing a live chicken at your reload bench is always good for another 50 to 75 Fps on max loads.... thumb
