A couple of weeks ago I started the load workup on a new Weatherby Vanguard S2 243. I loads with the 85 gr Partition, 90 gr AccuBond, 95 gr Balistic Tip and a 100 gr Sierra GK.
Though I didn't try a bunch of different powders on each, after the results I had, I'm sticking with the AB's and the Partition.
I ended up with the best targets being a max load of IMR 4064 behind the partitions putting 5 shots into .7" and IMR 4350 with a max load pushing the 90 gr AB putting a 5 shot group into .5". Both max loads are from the current Nosler book.
The reason I stopped with these two is that the point of impact for both bullets/loads is exactly the same!
So, this past Sunday, before the game, I went out to see how they did on the chrony.
I'm using a Magneto-speed to get the results shown below.
On the 85 gr Partition:
Series 1 Shots: 5
Min 3121 Max 3232
Avg 3174 S-D 47.1
ES 111
Series Shot Speed
1 1 3133 ft/s
1 2 3183 ft/s
1 3 3205 ft/s
1 4 3232 ft/s
1 5 3121 ft/s
For the 90 Gr AB:
Series 4 Shots: 4
Min 3029 Max 3072
Avg 3050 S-D 17.6
ES 43
Series Shot Speed
4 1 3053 ft/s
4 2 3048 ft/s
4 3 3072 ft/s
4 4 3029 ft/s
Only picked up 4 shots on the 90's. It was too windy to try longer range, though we can shoot out to 600 on my friends place.
My friend ran the numbers through a program he has and both should be good to go on Texas whitetails out to 450 yards.
My next plan is to load a bunch up and head out there for an all-day shooting extravaganza out to the 450-500 yard mark just to see where the scope/rifle combo will go.
Once that is done I'll put together a 'cheat sheet' for each load, laminate it and tape it to the stock. Then it's practice, practice and a little more practice.
