Re: Load Data - 340 WBY

As LTLR said 7828 is a great powder. I was trying heavy bullets and retumbo since I like it in my 338 Norma.The 340 is not far from this and I just had a hard time getting those long bullets in and I was using a long drop tube and compressed.My old load of 92 gr.7828 kicked out a 225 gr. at 3000 + and worked well for me.Probably what I'll go back to or a 250 gr.

Re: Load Data - 340 WBY

I was on Weatherby site for years.This site in general pushes the limits more and with heavier bullets,There are a ton of Weatherby shooters on here.I would almost bet LTLR HAS or had about every Weatherby made . He has alot of experiance with there largest offerings also

Re: Load Data - 340 WBY

Started working on loads with the H1000 (I already had this on the shelf.) Best estimate is a starting load of 80.0gr behind the Barnes 280gr LRX bullet. Potential maximum is 88.0gr. The starting load was crushed with the bullet. I stopped loading at 83.0gr. I'll test these four for starters.

Personally, I don't much like or trust compressed loads. I'm going to pick up some IMR 7828 and RL-22 later this week. These should load in with a bit more room than H1000 or RL-25.

LTLR - Thanks for the load data for the 265gr. I'll work on something around those weights.

Re: Load Data - 340 WBY

Not sure if this will help or not, but here is some 285 TSX data from QL..


Cartridge : .340 Weath. Mag.
Bullet : .338, 285, Barnes 'TSX' BT 33850
Useable Case Capaci: 78.402 grain H2O = 5.091 cm³
Cartridge O.A.L. L6: 3.675 inch = 93.35 mm
Barrel Length : 26.0 inch = 660.4 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 64000 psi, or 441 MPa
or a maximum loading ratio or filling of 110 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

161 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

If you see a powder in there you want a profile ran of, let me know. Good luck.. Sounds like a really cool loading project.

Beretzs, that's a ton of data and is truly awesome. Thank you very much. I can use this to validate or (in the case of my H1000 loads) invalidate my assumptions. Looks like I have a few bullets to disassemble now but glad to do so. I was nervous as soon as the first one crushed.

Re: Load Data - 340 WBY

If you would like more accurate data, for a specific powder, weigh a FIRED, empty case from your rifle, then fill that same case with water, all the way till it will not hold anymore. Weigh that. Give me the difference, that is the overall case capacity in water. That can be used to give a more accurate charge recommendation with QL. Running the program only takes a few seconds, so if you need something specific hit me up, happy to assist. Scotty
