Time to think about some loads and stockpile some components for my upcoming .270 Wby. Have accumulated some 130 gr. Ballistic Tips, some 150 gr. Partitions and a bunch 140 & 150 Triple-Shoks (hope to make some magic with these). I've got a bunch of brass to get myself started but am looking at my powder stock and everything is pretty much geared to my .30-06 and my .243 (lots of IMR 4350, IMR 4895 and Varget).

I've done some reading online and a preferred powder for this combo of TSX/.270 Wby seems to be either H4350 or H4831 but not alot of actual load data is available. Barnes says to basically take their data from the comparable "X" bullet and add 1-2 gr. onto the max. load for the TSX as a max for this bullet due to reduced pressures. They also say to seat the bullet .05" back off the lands.

Anyone have a favourite that works for them? What primers would be a good fit? I think I have some Win lg. rifle and some CCI BR rimers downstairs now - anything else will go onto my shopping list ;) .

Thanks,
ILBR :)

Do you mean H4350 Ted?

If you've developed anything for the Barnes TSX or "X" or even Partitions I'd love to see what you came up with.

Thx,
Jerry


Jerry, it is good that you have asked this question.

Many powder names are similar and can lead to confusion and trouble if guys are not careful. This, of course is why it is so important to be absolutely certain about anything you post or read on the internet.

H450 is what I have been using, not H4350. H450 is a spherical ball powder that is the same burning rate as Winchester sphercial 785. It is quite a bit slower than H4350, just a bit slower than H4831, a tad faster than RE22.

H450 and W785 WERE the same powder. When Olin discontinued W785, then H450 wasn't long in going away as well. I used many pound of it in my 270 Wby.

You can still find it here and there, but for the most part supplies are gone. That's why I use mostly RE22 now. It can easily make 3500 with 130 gr bullets and mag primers. :D

Here's a good start on your loading quest, especially if you want to use one powder for all bullet weights: http://www.imrpowder.com/data/rifle/270weathmag.php

Ted,

You're too popular a guy :D . I got the PM but when I tried to respond to you it says your pm's are beyond the allowable limit and you can't receive anymore until some have been cleared. ;)
