    Default 338-06 2700fps

    What are you guys loading for your 338-06. I plan on shooting 210 partitions and I would like to reach 2700FPS. I'm not dead set on this, but that is my goal. The powders that I have been looking at are 760, varget, and imr4320, or imr 4350. I have those on hand so that does influnce it a little. What are you guys shooting?

    I shoot the AI version. I found that I got good accuracy with all the powders I tried, but didn't get the velocities I wanted until I switched to IMR 4895.

    I have a 24" barrel and have no trouble reaching 2700 plus FPS with Nosler 210 PT's using either RL19 or H4350. I am still doing load work up using RL17 on this one. Also, I have reached 2700 FPS with 225 grain Hornady SST's. This is from memory, I can't give more details at this time because I am not where my load book is.

    If your rifle shoots the 210PT's well, you should easily be able to reach the 2700 with one or more powders. A lot of 338-06 folks dote on the 210PT, and it is awesome, but I think the various standard 225 grains are underrated for this cartridge. Shooting any 225 grain cup/core at 2600-2700 FPS out of a 338-06 is serious energy and sectional density! My experience with two different 338-06's is that the 225's shoot more accurately than the 210PT's. You have another option now also, Nosler offers the 200 grain Accubond in 338 now. Enjoy, I have had a lot of fun working up loads for 338-06. It is an easy cartridge to develop loads for.

    I'm loading Barnes 210XBT over RL-15. Am still fine tuning and have not bothered to crony any yet, but the groups are very good and all the animals have fallen over dead so far...

    i have always wanted one..........the .33 caliber is both functional and facinating. ballistically superior to the .35's in an "06" or .308 case this bullet performs wonderfully, and at standard velocities. operating at about 100yds short of the .338 winchester magnum this cartridge only needs more press-time to recieve the acceptance it deserves.

    personally i like the 200gr with 56gr of imr 4064 and the 225gr, with 62gr of win 760
    happy trails.

    I recently bought a Tikka T3 Lite in 338 Federal and I chose the Tikka because it has a long action (using 06 mag) and I figured I could seat heavy bullets out a lot longer OAL than with the short action. I have had fleeting thoughts of running a 338-06 reamer into the chamber to get a bit more out of the very light gun and have pretty well figured there was really not a lot to be gained for the effort. The stock 338 Federal will handle anything I need to kill in the Americas and most of the rest of the world when the proper bullet is placed in the right spot.... a 100 or 200 FPS will not change that fact and only cost a few inches out to 300 yrds.

    I have a 35 Whelen in a 10 lb Savage and I gotta say the 7 lb Tikka is a lot nicer to carry but I think the Whelen kicks as much as the Tikka....light is a good thing in the mountains. Guess I'll pass on the 338-06 for now, but it is a fine round.

    swapdonkey, just read your your question on 338-06 2700fps. What did you end up loading to gain those particular ballistics? Reason I ask is I just bought some 210gr Scirroco's and want to work up a load. Right now I'm shooting 200gr Speer Hotcors, for fireforming, at 2850 fps with 57.0 IMR 4320. I shoot the AI version. I also use 62.0gr H4350 with 225gr Interbonds. All with great success. Ozarks, my rifle shoots the 200gr bullets more accurately than the 225grs. What powders did you use with 225grs? Thanks guys.

    I have shot a lot of IMR 4064 out of my .338-06. It has been my go-to powder in .338-06 for a long, long time.

    I played with RL-15, and found it promising with 200-210gr bullets. I never tried it with anything else.

    I also got great accuracy with IMR-4350 and 250gr bullets.



    IMR 4320 never showed me anything exciting in my particular rifle. The 4064 always did better.

    Dan, I just checked out 4064 on the The Reloaders nest. I think I will have to try some. I do get great results with 4320 and 200grs but will try 4064 regardless. Thanks.

    Lager,
    I worked up from 58.5 to63.5 grains of RL17 using 225 grain Hornady SP, not SST. Best accuracy at 63.0, shade over inch. Chrono avg. 2728 fps out of 24" barrel.

    Correction: I quoted wrong velocity, 2728 was with 63.5 and accuracy fell to 2.75. 63.0 grains averaged 2710 fps. This was at 28 degrees Fahrenheit.

    I got my most accurate load ever fired in this rifle (my 2nd 338-06) from Murphy: Nosler 210 partitions, 62.0 grains RL19. Shot a 0.60 inch 100 yard 3 round group from bench as fast as I could recover and shoot again.

    Also meant to add that this rifle has free bore and long magazine and i take advantage of both, so work up to the charges I give. This rifle can handle more powder with less pressure than previous one with no free bore.

    My 338-06 load in my WBY

    55.0 of IMR 4320 with 225gr Speer GS or Partition
    even good results with Hornady 225gr SP.
    Fed 210M with Norma Brass

    I use to use 210gr Part and 200gr AB and BT but seem they were alittle light for moose.........but the 225gr has the better Sec Den (SD) for moose.

    Finally got to the range yesterday to test out some RL-17. Tried three different loads with 225gr Hornady IB. Started with 59.0, then 60.0 and lastly 61.0. None showed any signs of excess pressure whatsoever. Speeds were, starting with 59.0- 2682 fps avg, 60.0- 2745 fps avg, and lastly 2760 fps avg with 61.0gr. Best group was with 61.0gr and was 1.25 in. That's 60 fps faster than my heaviest load with H 4350 and primers starting to flatten out a bit. So overall, very happy with this new powder. May try another half grain or so in the future. This is with 24 in barrel. Cheers.

    54.0 of IMR 4320 with 225gr bullets is what I settled on in my 338-06.

    Finally got to the range yesterday to test some more with RL-17. Here are some numbers. Loaded 62.0gr under a 225gr Hornady IB. Velocity measured 2805fps avg. The 3 shots grouped 1.5 in. Primers were starting to flatten but were not bad. The second load I tested was 63.0gr with 210gr Scirocco. It measured 2905fps avg with just over an in group. No pressure signs with this load. Extraction with both these loads was normal. No sticky bolt. Pretty sure the load using 225gr was near max. Will use either one of these loads for hunting. Should mention that primers used were CCI 250 and brass was new Winchester 30-06 necked up. Very happy with these results.

    My pet 338-06 ACK load is

    250gr Barnes TSX
    60 gr of H414
    CCI 250
    Once fired Rem brass

    its a warm load but safe in my gun
    Velocity 2625
    .625" 3 shot groups

    Thinking of going to a 225 TSX of possibly a 250 A-frame that 250 TSX is just so long that it is eating up powder space

    I keep throwing the 338-06 and the 35 Whelen into the thought pot and never seem to come out with the same answer. The 338-06AI kinda throws a new spice into the mix though. Hmmmmm......

    An ultralight 338-06 would be mountain gun perfection (In Alaska, NWT, and BC) in my opinion. Right up there, would be the 338 federal, the 338 RCM, the 358 winchester, and the 35 whelen.

    I have a custom 35 Whelen AI which is a great rifle, but I had it made 20 years ago.

    With today's choices, I'd go 338 RCM and never look back.
