does anyone with weatherby mags have any pet loads for 270wm and 340 wm with tsx. I am not sure where to seat bullet as freebore does away with .050 off lands. i will be using 225 tsx in 340 and 140 tsx in 270. thanks

my 270 wb load is 67 gr of old H4831 and a 150 partition. The rifle however isn't a weatherby but an old M70 and the barrel isn't freebored.

In my 340 (factory chamber=freebore) we determined OAL by using some of the Weatherby factory ammo. The factory stuff shoots extremely well, and we were basically trying to dupicate it with handloads. Using 7828SSC, we got pretty damn close! Try that method and see what it does for you.

gerryb 270Wby Wby cases CCI250 73 grs IMR 7828 and 130 gr TSX. Max load in my rifle and it shoots 1/2 to 3/4 in groups @ 200yds in my rifle.

340 wby Wby cases Fed 215 90 grs RL 22 and 210 gr TSX. Under 1 in groups @ 200 yds in my rifle.

Both loads are max so start 4 or 5 grs below and work up carfully. Hope that helps

I think gerryb was looking for the overall cartridge length for the loads also. I don't know mine off the top of my head, but am now curious what others are seating their bullets too also.

gerryb I believe Barnes recommends being at least .050" off the lands. You are likely correct in saying that with the Weatherby freebore you will have a lot more than .050". I would suggest you size about 1/8 "of the neck on a fired case in each calibre. Set the bullet of choice on top of that case (no primer or powder)put it in the chamber and close the bolt. When you extract that case that will tell you where the rifling is. Then I would suggest you seat the bullet out as far as possible and still function through your magazine. Make sure the dummy round that you seated the bullet by chambering is at least .050" longer than the one that fits through the magazine and you should be set to start loading your test loads. Start at the suggested starting load and work up one grain at a time watching for sings of excessive pressure.

My 340 WBy is a custom short throat i.e. no free bore so it'd be irresponsible for me to share my loads. The key to a Wby is to make sure your COAL fits in your magazine well and then go from there.

270 Wea (Mk V) 150 Hdy SPIL, Norma Case, Fed 215 GMM, 71.5 grn R22. 3265 fps and sub 1" at 200 yds. Work up to it. Absolutely devastating on deer. IMR 7828 will do about 1.5 at 200 in the same rifle, just not quite as accurate in this one.
