You all have to try this load 300 WSM :

IMR 4831 @ 70.0
165 or 168 TSX
WLRM Primer
WW Cases

I get 3200 FPS in a Win 70.

3100fps@ 15'

Added velocity data.

Same load as before.
Top target is 100yds.(0.75")
Bottom target (or lower part there of) is 350yds
(3.75")
Avg. velocity for the load is 3140fps.

I'm currently working up a heavy bullet load with IMR-7828.
The first results with the 210 berger VLDs looks promising.

I just started load development with my rifle with 200 gr. TSX. I'm getting .75 inch groups at 100 yds. and 1.8 groups at 200 yds.Things are looking good for only 2 range sessions..

150 ct ballistic silvertip
65.5 gr ww-760

winchester brass
this load is a one holer at 100 yds out of my
tikka t3 lite 300 wsm

Kimber montana 8400 300wsm,
winchester brass and WLR primers - gonna try some fed 210s
nosler 165gr BLTS with 71gr VV N160 - dont try this load in your rifle as books max is 66.8, work up to this slowly. although im having no pressure problems. Unsure of velocity but 67gr was 3000fps so this may be near 3200FPs

Kimber montana 8400 300wsm, winchester brass
168grain Berger VLDS MOLY, 68gr VV N160 Federal 210 primers 3 shot 100yard groups. still working up loads.

after a bit of shooting they have done .5" and 3/4" did one group at 300yards being 3"

These are 2 loads I worked up for a browning 300wsm

Swamp_Fox did you chrony any of those 210gr loads? im trying some berger 190gr VLDS and my most accurate load is doing 2900FPS.

Win M70 Stainless Classic:
Hornady 165 SST 66gr IMR 4350
Barnes 130XLC 66gr IMR 4064

With the 130, I've taken pigs up to 300 pounds. It's my favorite but, no longer made. Gonna have to give the 130TSX'x a try.

I no longer use a chrony. I just watch pressure and accuracy.
