Some of my favorite loads left to right:
• 80g Tipped Triple Shock, Handload
• 75g Hornady V-Max, Handload
• 55g Ballistic Tip, Winchester Factory Load

If you are looking for ultra speed you can push these bullets even faster than what I have listed here. I like to keep my loads away from the highest pressures possible. The loads here are my goto sub minute-of-angle accurate hunting loads. For varmints, I either use the 75-grain V-Max or the 55-grain Ballistic Tip Winchester factory load. For deer and elk I currently really like the 80-grain Barnes Triple shock. That bullet has performed very well on elk. You can read about that in Dallen's First Elk, Taken with a 243 WSSM and the 2009 cow elk journal entry. I am very comfortable with this 80g TSX bullet on elk out to 350 yards. Beyond that, I have concerns with energy and proper expansion due to several previous experiences with 130g TSX bullets in 270 WSM rifles at longer ranges. You can read more about my thoughts on the Triple Shock in my Recovered Triple Shock Bullet journal entry.
Another interesting thing in regards to speed. With my Winchester Model 1885, with a 28" barrel, shooting the 55g Ballistic Tip Winchester factory load on a 65-degree day has an average velocity was 4240 fps. It also consistently shoots this load under an inch at 100 yards. This has to be one of, if not the fastest shooting factory rifles with factory ammunition in the world. It does amazing things to chucks and prairie dogs. Wow!
I'm still looking for a long-range deer load (350 yards and beyond). I thought the Hornady 85-grain InterBond might be the ticket. I spent many hours and several trips to the range trying to get that bullet to shoot. I tried four different powders and many different seating depths. The best I could get was three-inch groups at 100 yards. On the other hand, every load I tried with the 75-grain Hornady V-Max shot well. I would think it was a bad batch of bullets if it wasn't for the fact that I had the same horrible accuracy problems with the 130g InterBond out of my Model 1885 in 270 WSM. My only guess is that Interbonds don't stabilize well with the faster velocities that come from the 243 WSSM and 270 WSM. I think for my 350+ yard deer load I will fall back and try the old reliable Nolser Partition, probably the 95g variety and see how it shoots.
I'm working on a load for the 95g Nosler Partition. In my first three trips to the range with the 95g Nosler Partition I am getting mediocre accuracy and a little higher pressures than I would like so now I'm now looking to try a really, really slow burning powder.
I found the 95g Nosler Partition load I like... well, maybe I'll tweak it some more in the future but for now, I'm happy. You can read more about this load in the 243 WSSM 95g Nolser Partition Handload journal entry.
Oct. 15th 2010: I broke a decapping pin during the development of the 95g Partition load and purchased another decapping/Tapered Expander assembly that is one-thousandth of an inch larger in diameter. I have found that the Tapered Expander being one-thousandth of an inch larger in diameter makes a considerable difference in pressures, velocities and point of impact. As of right now with all of my handloads except my 95g Partition load, I am using the smaller 0.242" diameter Tapered Expander.
Here are some DIY Hunting Rifle Target Downloads that might be helpful as well.
|Bullet||Powder||Primer||COAL||Barrel Length||Muzzle Velocity||Notes|
|105 Gr. Hornady A-Max||45.8 Gr. Hodgdon H1000||WLR||2.3530-2.3560||24"||3070||Great Accuracy. See target groups and more information on this 105 A-Max load. 243 WSSM - 105 Gr. Hornady A-Max Hand Load|
|95 Gr. Berger VLD Hunting||46 Gr. H1000||WLR||2.434||28"||3220||
Awesome Accuracy! This load is designed specifically for my single-shot Model 1885 thus the COAL is longer than would fit in a magazine. This load was used on these long-range shots.
|95 Gr. Berger VLD Hunting||51 Gr. Accurate MagPro||WLR||2.434||28"||3330||Great Accuracy. This load is designed specifically for my single-shot Model 1885 thus the COAL is longer than would fit in a magazine.|
|95 Gr. Nosler Partition||46 Gr. Hodgdon Retumbo||WLR||2.270||24"||3165-3250 fps||Sub MOA, This load shot 3250 three different times at the range with a slightly longer COAL. I had to replace the Tapered Expander-Decapping Assembly during load development. The new one is 0.243 in diameter and my old broken one (Oops!) is 0.242 in diameter. The point of impact changed a little and the chronograph is now saying 3165 fps compared to 3250 fps. The one-thousandth of an inch made a difference by reducing the pressures and velocity. 243 WSSM 95g Nolser Partition Handload|
|80 Gr. Barnes Tipped Triple Shock||51 Gr. Hodgdon Superformance||WLR||2.250 (everything I tried between 2.236 - 2.265 shot well)||22"||3550 fps||Sub MOA. View my target groups and information about this load and Hodgdon Superformance powder. 243 WSSM Hodgdon Superformance Hand Load Testing|
|80 Gr. Barnes Tipped Triple Shock||52 Gr. Accurate MagPro||WLR||2.265||22"||3360 fps||Sub MOA. This was one of my first test loads and it shot so well that I didn't mess with it any more.|
|Same 80g TTSX load as above with a different rifle||24"||3475 fps||Sub MOA|
