Does anyone know the min and max amount of RL19 for Barnes tipped TSX 225 grain. The caliber is 338 win mag. I just bought a box of these bullets and a new Barnes manual and they only list 4 powders for this bullet. I was told that the tipped info is the same as the regular TSX bullet. Thanks.

The Barnes 338 225 gr Tipped is 33879

My Quickload shows four other Barnes 338 225 gr bullets in the library, but not that one:
.338, 225, Barnes 'TSX' S 33846
.338, 225, Barnes 'X' S 33885
.338, 225, Barnes 'XLC' S 33855
.338, 225, Barnes Solid BT 33821

Using the 33846, RL19, 338WM, 3.34", 24", 64,000 psi, I get 72.5 gr, 107.9% powder fill ratio, 2874 fps.

backing off to 100% fill, 67.18 gr 50,278 psi, 2644 fps.

I don't know how much powder you will be able to compress, probably somewhere in between.

Thanks for that info. I'll just start at 68 grains and work my way up from there. That sound about right?

That sounds like a good idea to me, but I have never actually shot MY 338WM and I have never worked up a belted magnum until the primer pockets loosened.

Ass Clown calculated* that the 300 H&H case head was good for 5,000 psi more than the 7.63x53mm Mauser case head.

I can get long brass life in a Mauser case head at 58,000 ~ 62,000 psi, even though the SAAMI registration may be from 37,000 in an 8mm to 65,000 in a 270.

So my guess is that the SAAMI registration of 338WM at 64,000 psi is about right.

* ASS_CLOWN was an AR contributor that could calculate Von Misses stress for different cartridge case heads

I can't speak for the 338 Win but I have loaded the 225 grain TSX, TTSX and MRX bullets for my 338-378 Wby. I originally used the Lyman 48th edition and the Barnes 3rd edition for my load development. They agreed pretty close on load data for the Barnes X bullet. According to Barnes, at the time, you could use the same data for their newer bullets as was used for the X bullet. I found this to work very well. Their 4th edition manual seems to be using data for riles that done't have the Weatherby factory freebore so the new manual doesn't do much for me there. I did notice the lesser number of powders they worked up loads for as well. See if you can find their 3rd edition and you will find more powders listed.

Ken....

I don't know about the tipped bullets either, but I compared the loads listed in the 3rd and 4th manuals to come up with a load for the 225 triple shock. My load is 69 grains RL19, Fed GM215M primers, Win cases, OAL 3.320". My loads chrono @ 2700 fps out of a pre-64 model 70.

I've been loading the 225 TTSX for my 338 WM for a couple months now. I'm using IMR 4350 as opposed to RL19. Barnes web site talks about load data for TSX bullets. I just used the TSX load data and increased the charge in 1/2 grain increments til my chronograph told me I was getting comparable velocity. I'm not getting any pressure signs either and just this morning verified my zero and clocked em at 2750 fps. That's fast enough for me. FYI, I emailed Barnes to get the B.C. for these bullets and they don't have the actual numbers yet, so he told me they are estimating the B.C. to be .410. I'm lookin forward to shootin somethin with em.

Barnes sometimes change their minds about BCs, but they do currently list BC (.514) for the 225 grs TTSX on their website:

mho,

Thanks! That's a big difference between their guestimation and their published info. I read they are now calculating the B.C. at 300 yards as opposed to the previous 100 yards.

I can never quite get my head around Barnes' BC numbers. Sometimes they publish fantastic numbers, but then they change their minds and recalculate them at lower levels. It is all a bit confusing...

225 is a heavy bullet for TSX, I would consider going to something a little faster if I were you.

If you are interested in a slightly lighter bullet, my 338 Win. likes the 210 grain TSX at 2900 fps. I use H 4350. Without looking it up, I think it's 70 grains. DW

I've got some .338 225gr tipped TTSX BT 30430 bullets. Are ordinary starting loads from the Hodgdon/ADI manuals applicable? I usually use H4350 or H4831 equivs but do have some Re19.

Sorry if that question was beneath contempt, so long after the OP, but I'd really like some input.

'The Derek' may have been on to something with his observation that 225gr was "a heavy bullet for TSX". It is certainly a long one, which is problematic with the short throat in my old Sako Finnbear, meaning I'll have to cut the COL to 3.25 inches and seat about 0.7 inch into the case.

This will take up a good amount of powder space, so even without advice on the pressure properties of Barnes's copper, I'm considering starting at about 61 grains of AR2209 (H4350?), two grains less than the listed base load for the 225gr Hornady SP.


I'm also using CCI 250 primers and Norma cases, while ADI used Winchester cases and LRM primers. So, should I start even lower?

Anyone, anyone?

PS: The Barnes online manual doesn't mention H4350 for use with with the 225-grain bullet - but that's what I've got most of and the powders it does mention are not available here at the moment. By extrapolation from surrounding tables, I figure 60 grains might be a safer load to start with considering my reduced COL.

Tell me if this logic is dodgy. The Barnes table has the 250-grain loads for H4350 all of 0.1 grain lower than the IMR4350 loads. Could it be they just didn't bother to test H4350 for the 225-grain TSX?

Shoot Barnes an email, or call them. They have been very helpful when I have done so.

Based on belt mic WW case. FED 215. 210 Nos and RL-19.

76 grs .0004 vel 2940 fps
77 grs. . 0008 vel 3000 FPS
78 grs. .0014 vel 3024 fps

I got about the same with the 210, 225 Nos, 200 or 210 TSX ( one or the other, sometime ago)

My hunting load for both is 77 grs. as nothing much changed in velocity so why load warmer unless your squeezing in more unneeded vel. plus accuracy was a tad better. I went up to 80 grs. and ran backwards!!

Thanks Ray, I'm finally going to the range Monday, but after 21 shots I'll still only have worked up to 65 grains of our AR2209 (H4350?).

I've got the 9.3x62 and my son's 35 Whelen to sort out, too, so it might be a long day.

Old finnbear action. Lilja barrel put on in the 90s. W-W brass, federal 215GM primers, 225 triple x, OAL 3.325. RL 19, 70-74.5 loads pressure ok. Chronograph 2891 @74.5. 74.0 was best load, 2871-2880 chrono. 1” @ 100 groups.

Hope this helps. I would quit, for sure, when velocity touches book max for ttsx bullets. Or any signs of pressure. Book max seems hard to find, but I’m guessing a bit under 2900 fps. Again, check for all signs of pressure.

Calling Barnes is an excellent approach to getting the right answers.

Thanks HT, I've got up to 65 grains of AR2209 with no pressure issues, and am amazed at the improvement in accuracy as the loads got heavier (several three-shot groups under an inch, off my steel skateboard on a windy day).

I'll probably load up to 69 grains, almost max in my manual.

I got up to 67.5gr of AR2209 but found the belt expanded about one thou on the highest load, so I might back off a grain.

The velocities were a bit disappointing, only getting to 2650fps, but the accuracy was surprisingly good, esp. on the very windy day I went to the range, so maybe these bullets cut through the wind very well.

Early on I lengthened the throat in my M70 .338, installed a .375 mag box, follower and bolt stop, so that I could load to 3.6" oal. This really helps the .338 by letting you seat the long bullets out giving you a little more room in the case. Loaded this way my rifle really likes the 225 ttsxs. I get a bit over 2800 fps with Re22 or IMR4350.
C.G.B.

Thanks CG, a buddy lengthened the throat in my .45-70, making it an ersatz .45-83. So, since the Sako has a long action, I might ask him if he can do that to my .338, too.

I haven't been able to get beyond 2640fps with mine but can't believe the winď-cheating accuracy of those bullets. Despite a 20mph side wind, two powder-weight changes and dropping the elevation half an inch, eight bullets went into 1" (across) by 1.13" on Friday. A flier made it nine shots into 2.5 inches but I reckon the wind must have dropped for that one
