I'm working up a load for my 300 WSM with 180gr AccuBond and H4831sc, so far I'm getting 4 shot inch groups at 100 yards, I have one more load to try before I make this my go to load.Anyone else had any luck using this powder in a 300 WSM?
 
Never loaded for the 300WSM, but it uses very similar powders as the 300WM and H4831 is a good one in it. Another that might be good is RL22, but if you are getting 1" 4 shot groups, I think you are there. What kind of speed are you getting out of the AccuBond? Scotty
 
techumseh,

Welcome to the forum. You will find a great group of fellows here. Generally speaking, medium burn powders perform quite well in the 300 WSM. One of the powders that performs very well is H4831SC. I use a surprising amount of IMR4831 and H414 and W760. All work very well. With the 180 grain bullets, a couple of other powders that work very well are VN550 and VN560. Slower burning powders will work, but I seem to get better accuracy with the powders listed.
 
Thanks guys, The manual is showing 2923fps, I'm going to check it after the next load I try. I've tried H4350,IMR 4350,IMR4831 and RE-19, H4831sc is the best powder I've used so far.

Scotty,

I remember a time when a fellow shooter called me and asked for a load for a .22 Hornet. Well, I'd just got up from my nap and wasn't quite square with the world yet, so I gave him a powder-charge for a 22-250.

Last I heard of him, he'd moved off down to Georgia back-country and had finally gave up tryin' to pound that 40 grain powder- charge in that Hornet case :lol: :lol: :lol: :lol: .

I'm working up a load for my 300 WSM with 180gr AccuBond and H4831sc, so far I'm getting 4 shot inch groups at 100 yards, I have one more load to try before I make this my go to load.Anyone else had any luck using this powder in a 300 WSM?[/quote]


I'll look at my data at home for what I loaded for a friends .300 WSM and 180 gr. Accubonds. I came up with two loads with two different powders that shot amazing. I'll check and let you know, but I believe one load was H4831SC and the other was IMR4831. Several grains of powder difference between the loads because of the different burn rates, but what was fascinating was that both of these loads shot amazing groups, the velocity's were within 10-15 fps of each other, and they shot to almost the exact same POI. The pressures and harmonics had to just be about spot on. First time I've gotten that lucky with two different powders. I'll research my data and let you know.

Last I heard of him, he'd moved off down to Georgia back-country and had finally gave up tryin' to pound that 40 grain powder- charge in that Hornet case

That could've made for some fascinating range time.
 
Yeah, I can see someone wondering how the heck they got all that powder in the Hornet. "Must have been a 6ft drop tube!" Scotty
 
300 WSM loads. These two loads shot to the same point of impact within about 1/4-1/2 inch from each other and velocity was only about 15 fps different between the two.

Winchester cases - Federal Large Rifle Magnum primers - 180 gr. Nosler Accubonds
IMR4831- 65.5 grs.
H4831SC- 70.0 grs.

He as the OAL in his die book along with the velocities of each load so I don't have that to provide. They both shot superbly though!

Pop, isn't that data for the 300WBY? Just wondering. Scotty


Fixed it... :oops:

No sweat buddy! I am sure with the amount of recoil you have endured, you are allowed some leeway! Scotty
 
RL-17, 66gr. with WLRM primers and AccuBond 180 works fantastically in my A-Bolt Stainless Stalker
when I do my part I get 3/4" groups at 200 yds

techumseh,

Welcome to the forum. You will find a great group of fellows here. Generally speaking, medium burn powders perform quite well in the 300 WSM. One of the powders that performs very well is H4831SC. I use a surprising amount of IMR4831 and H414 and W760. All work very well. With the 180 grain bullets, a couple of other powders that work very well are VN550 and VN560. Slower burning powders will work, but I seem to get better accuracy with the powders listed.


Apparently no coincidence that H414 and W760 both work well in the .300WSM - Just found this tidbit posted on another site:

Hey guys, not sure if this has been posted before or not, but I found it interesting. I noticed that the loading data for H414 and W760 were close, but H414 is listed in more books. I later read on the internet that they are indeed the same powder.... Well if you read it on the internet you know it must be true.
I decided to email Hodgdon directly to get a real answer. Here is what they told me:
Yes, H414 and Winchester 760 are the same powder. The only difference
is the label on the bottle. This has been true since we brought out
H414 years ago.
