ballistics for a 32 inch barrelled .338

I don't understand the draw to have a 32" barrel on a rifle shooting hunting bullets. Some people just want what they want.
Yup. That part is a tad confusing to me too. But I still love the idea…especially as I ain't the one forking over the dough to find out if it's worth doing! 🤣
 
Hello and thank you,

I anticipated200-210-225 grain hunting bullets and have them coming, also 200 250gr. Hammers. In that wide span of bullet weights I will let the targets tell me what this unique barrel likes best and shoot that bullet exclusively. Thank you for such specific data which I cannot generate myself. I am surprised at the velocity from the longer barrel in .338 Winchester caliber, and expected more. You have given me data I could not get, would you be willing to run me 200 and 225 grain bullet weight data from this long barrel?
Thank you in advance,

WW



I don't have the newest quickload update yet , so I don't have any Hammer bullet info . give me the other bullets you're thinking on using .


just an FYI;
in my 338 Lapua , I run 300 grain bergers and 300 grain nosler custom competition bullets at around 2935 FPS .
 
I'm committed to this Win. chambering by the items I have on hand , arriving daily and also my past history of direct comparison of the various 338's at Whittington. Every point made here is valid, faster velocity ensures less reaction to wind, heavier bullets at a faster velocity are really superior, especially at long distances. That being said I also know about the human factor and a humans' response' to recoil. I simply shoot the .338 Winchesters more accurately. I have shot well enough to have set two worlds records at long distance. In addition since I saw my last patient 14 years ago before retirement I know exactly anatomically which nerves in what location are being affected when the trigger gets squeezed. I do not demean other peoples choices and certainly understand other superior ballistic arguments. But, as for me, even with all the superior advantages commonly available nowadays: heavier longer, better made barrels, superior bullets and ammunition, advanced muzzlebrakes, superior optics, etc., recoil is recoil and no amount of weight can reduce its total effect on the nervous system. My friend who has passed on had a superior, highest quality .338 Lapua Improved that shot really great groups with the 300 Berger bullets. Paul knew what he was doing when he sat at the benchrest. That rifle weighed 47 pounds. I know I carried it for him to the benchrest in Idaho, ONCE.
 
Jim,
Here are the bullets I have bought in a group for this rifle:
200 gr. Nosler Accubonds
210 gr. Barned TTSX
225 Sierra
225 Barnes TTSX
250 gr. Hammers
I have had this cd from Quikload with no upgrades for so long that my CD, which has not been used in a decade(?) may simply no longer function. Thank You for helping me.

I don't have any Hammer bullet info . post #2 is Mr. Steve , owner of Hammer bullets . I'll bet he can offer up some load info for you .




your quickload disk ;
I think I'd try reloading it on your computer . I don't think it would expire from nonuse . if that don't work give https://www.neconos.com/quickload-ballistic-prediction-software/ a call . I've only called them a time or two , I got my answer , and was an easy guy to talk to .
 
Jim,
Thanks for being so helpful and you can be sure I will be retaining this data and also contacting neconos. That wasn't the name of the firm that developed this software.
Thanks again.

Gene

I have purchased a 33 inch unchambered .338 barrel. Having shot a relatively wide example of well made .338 caliber rifles at NRA Whittington I find I shoot the .338 Win. mag the most accurately at distances to 1,000 yards. All this barrel length, using the right powders lead me to believe I can attain near Lapua like velocities with about 20% less powder charge. From an applied physics standpoint this seems pretty unique.
Right now, for some reason ,my Quik Load disc will not activate, so is there anyone willing to take the time and run some data for me to find out which three powders work best in that WIN. case with 85 grains capacity for the .338 Winchester with a finished 32 inch barrel using 200-225 grain bullets? I sure would appreciate finding this out. Also is anyone else having problems with their QUIKload discs?
Interesting approach, I will follow this thread. As far as bullets you may want to look at a .338, 265 grn long range accubond, I have a 338 win mag as well but was looking at a 33 Nosler, which may be a better choice for what you are trying to do. If you have success may look at a much longer barrel when I re-barrel again.
 
My next personal project is a 338 Win so I get what your trying to do, I also love pulling out a 308 but is running 215 Bergers and absolutely crushes at 1000+, I really like maximizing smaller chambering and finding their long range sweet spot BUT I can not make sense of the bullet choices, the bullet is absolutely the key to getting performance, what you have are absolute BRICKS ballistically without the speed to cover for that. Running the numbers even a 6.5 Creedmore with a 147 ELDM has less drift than your selected bullets even running hard. Now switch up to a bullet like a 250 Berger ya you'll loose some velocity but the ballistic gain is outstanding especially at longer ranges.
I'm wrapping a similar build around the 250 Berger for long ranges and the 213 Hammer Hunter for closer stuff so I can maximize the smaller chambering!!
