Has anybody tried Staball 6.5 in 243?

[ReloadKy]

I am trying out staball 6.5 in my sons 243 with a 100 gr Partition to try and find a speedier load for upcoming deer season. Anyone else tried this powder out in 243?

I had 3 powders in mind to try; IMR 4451, Staball and Hybrid 100V (I have plenty of all 3). The reason I want to get a little bit more speed with the Partition is because my son has a compact rifle with a short barrel so the velocity is going to be low. Historically his rifle is 150-200fps slower than published data. The faster I can start the better in terms of producing terminal energy. Hodgons reloading data lists these 3 powders as producing some of the top velocities. If anyone has any advice on any of the 3 powders with the 243 please share.

My truck gun is a 9 twist, 22" barrel Ruger American that I use StaBall with 80g Hammer Hunters. They are very accurate and average just under 3400 fps. I shot a coyote with that load at about 200 yards and he was DRT. i use RL26 with heavier bullets, like the 108g ELD-X, it gives me the good accuracy and velocity.

StaBall should work well with 100g Partitions.

 

[jimbires]

if you have IMR7828ssc , give it a try . it should give close to top velocity with the 100 gr weight bullets .


edit to add ;
I just looked , one powder gives more velocity than IMR7828ssc , that's RL26 .

 

[jimbires]

the 243 is rated to 60191 PSI . here are the powders you mentioned . these are the velocities you could potentially reach , if you don't over pressure before max load .

Haven’t worked with it in 243, but have had great results with it in 270 Win. 56 grains gets me 3128 fps with 130gr BT’s.

Try working up a load starting with 100V data. Staball is one step slower than 100V on the burn rate chart. It usually gives substantially better velocities than 100V, but that should be a safe place to start as 100V is one step faster than Staball. Work up slowly and let us know how it goes. You’ll start getting best accuracy and velocity when you reach 90-93% load densities.

 

[ReloadKy]

The first attempt with Staball did not go well. My velocity average was 2754 and the 4 shot group was 4.3 inches!!!! I think I am going to try the 100v. My son's rifle is a Rem 700 compact with 18 inch barrel so I know I am going to be lower than the velocities provided by Jim. Thank you for that Jim. I can get an average of 2800 and good accuracy with IMR 4831. I should probably just use that and be happy but I am being greedy and should not be.

 

[jimbires]

awe shucks , I ran the info with a 20" bbl . I should have mentioned above ; IMR7828 is long cut kernels , it's to bulky for easy use in the 243 . I used it before there was an IMR7828ssc . IMR7828ssc is much better to work with in this combo . max load is 101% case fill for the ssc . as compared to the long cut being 107% .

I know all powders are hard to get right now . I think you might find IMR7828ssc easier than RL26 . I don't think the demand is as high . I did buy some IMR7828ssc from a local gun shop not to long ago , keep an eye out .

It's all about bullet placement. Put that 100 gr PT exactly where it needs to go and your son will have dead deer, even with a 2800 fps MV. I always had great accuracy with IMR4350. No idea what the speed was.
RL26 certainly looks like it would be a good powder to try.

Were you getting any pressure signs yet? That seems like about where Staball should start getting more consistent for a 18” barrel. If you weren’t getting pressure signs, keep going up slowly. Staball usually gives better velocities than 100V. Magnum primers helps Staball as well when it’s erratic.

After saying all that, you can’t go wrong with IMR 4831 in a 243. It’s one of those powders custom made for a 243 Win. Seems like IMR 4831 fits that bill in many different cartridges. There’s also no “in between” with it. If the rifle likes it, the bullets will just about go through the same hole on their own. If it doesn’t like it “they can’t hit the broad side of a barn standing inside with the doors closed.”

Joe I did not have any pressure signs. I have also found that IMR 4831 is very consistent in several different calibers. In fact my wife's 243 loves IMR 4831 with 95 gr SST's.

That will just about make a deer look like it was struck by lightning. I haven’t deer hunted with my 243 for years but 8 out of 10 times it dropped them in their tracks. IMR 4831 is great in my 270 and a 7RM with 130gr BT’s and 139gr SST’s. It also has a very low flame temp compared to other powders in that burn range. Easier on chamber throats.

I use SB 6.5 in my 6 CM with 105's and it is excellent. Getting right around 3100 from it in my little Howa. It also works very well in my 30-06 with 212's. I'd surely give it a shot in a 243 with a 100. It can't be any worse than any others, and being a ball, it loads quite nicely.
