Does anyone have a good load (or load data) using ball powder for a 300WSM load using the Barnes 180gr TSX bullet?
I've been loading the 200gr TSX with H380 with good results, but want a 180gr bullet load for a little more speed.
I'm shooting in a rifle that has an unusually short throat (or whatever the opposite of freebore is). I'm having to seat these bullets pretty deep to keep them off the rifling. I've found that the h380 works great as it doesn't require as much volume. I can get a good hot load for the 200gr bullet that has the bullet seated deeply enough without compressing the charge. I've tried working with stick powders with the 180gr bullet, but no way to do it without compressing it. I'd rather avoid compressed loads if I can.
Barnes lists H380 data for the 200gr TSX on their web page, but not for the 180gr. Is W760 a ball powder?
All Winchester powders are classified as "ball powder". I have never used W760 and haven't looked at data for it in a 300WSM but it probably will require more case space than you are wanting to give it due to its slower burn rate. This is just my ramblings and thoughts, so don't give up on it until you check it out for yourself.
Just had another thought. It really doesn't matter how the powder granules are shaped, but what does matter is burn rate. A faster powder doesn't require as dense of load to produce the same amount of chamber pressure as a slower powder. With that in mind you might see if you can find data for the bullet you are wanting to shoot in your 300WSM for H4895. This is a good powder and has a somewhat faster burn rate even though it is stick powder. I have used it in 22/250, 243Win, and 204 Ruger, and have also known it to be used for some 45/70 loads. It has great versatility, but be sure to reduce 10% from max load and work up from there because even though it is a fairly predictable powder it can be more unforgiving than a lot of other stick powders on the high end.
Yeah, I may do that. I tried firing the Federal premium ammo with the 180gr TSX in this rifle. It shot well, except that the bullets weren't seated deeply enough. You really had to crank on the bolt to get it closed -not something I want to fool with while hunting. And at $2 each time you pull the trigger getting familiar with it would be pricey.
But they shot around 3100fps according to my chrono. Seemed pretty good for a 180gr bullet in a 300wsm!
I'd love to find a similar load that I could handload. Anything over 3000fps would make me happy.
I just ordered a box of the 180s from Midway. I'll be curious to see how they do.
