300 WM loading data, Barnes and Berger?

[John125]

Does anyone have some loading data 300 Win Mag, Barnes 168 TTSX and Berger 175 and 190 VLD hunting bullets?

I have a healthy supply of IMR-4350 (preferred), and some IMR-4831, and IMR-7828.

Does anyone have a Barnes manual that they can provide the low and high charges and approx. fps?

Anyone know where I can find some Berger reloading data?

Thanks!

I'd be interested in the TTSX 168 300wm load data as well. gonna build some up for my mulie draw tag(it's an almost impossible draw) just in case one jumps up a little too close for the edge I'm having built, which also needs to get done in time! Gonna start with rl22 77-80gns, hopin 80 doesn't show too much pressure and keeps accuracy(looks like its on the high end), wanna get it as fast and flat as I can since its just a point and shoot setup. if it passess pressure test i'll probably load up some at 80 and see how well the gun(sako finnbear) likes em. will start at .050 off the lands, hoping its gonna be that simple since most of my time is gonna be burned up getting the edge figured out, not too confident on how well I can do that one, guess I'll see, my first endeavor into the WAY out there stuff, but the 168 TTSX's are gonna be there for backup inside 400 yds and a rush if need be.

I load 70.5 gr 4350 with rem9 1/2m primer with barnes tsx168s I get a little over 3100fps and can shoot 3/4 inch at 100yds with a factory savage weather warrior with the accustock and accubrake

I have used as much as 75.5grns of Imr 4350 under a 168 and 74 under a 178 but these loads were not at 3.34", the 168 was 3.450" and the 178 was 3.486" or jammed .005" however both are very accurate. Id start with about 69grns under the 190 .010" off the lands and you may start seeing pressure at 72.5 and that will get you about 3025fps from a 26" barrrel, do not do this in hornady brass it will not take it, it will show pressure signs way to early. I also do not reccoment the ttsx as it may go straight through and you may end up following a long blood trail with no luck, its happened to me, id use the 168 NBT or Amax. The amaxes are devastating at all ranges. Btw imo 4350 and H4831 are the best powders for a 300wm period.

so far this is what i got
RL22
TTSX 168
80 grns was too much pressure, had to drop down to 78 to make the ejector marks go away loaded em .050 off the lands and had fliers. Dropped the load to 77grns and heading back to the range tomorrow to see if they will cooperate a little better still at .050 off the lands. If that doesn't get it I'm gonna load em .075 off the lands and jump the charge back up to 78 n see if that makes it all better.

Shot some yesterday...doing OCW.

77.7. 3160. average fps just under 1moa at 300yds. I loaded them .005 off...

It was a little too hot outside...marage very very bad, plus we had a 8 to 10mph 90% from the right cross wind...
