.243 Winchester Powder
- Thread starter Warbone
- Start date
I use H4350 and H1000, running the 115 DTACs. RL 22 and RL25 also works well, but I have only used them during load development.
I've am having good luck with IMR 4350 and 95gr. Berger Classic Hunter bullets in my Win 70 featherweight. This is the only powder I've tried, but it works very well.

H4350 is pretty much the go to for .243 as well for the 105-115 class bullets. I've ran H1000 to and it works pretty well but you need a longer barrel like 26" or more for it to work well.
With 87gr V Max and 95gr SMK I have had good luck with both 4064 and 4320. With 70-75 bullets I like 4895.
Using Alliants Power Pro 4000MR with good results. 105 Amax's at 2850 out of a 16" barrel. Fast and handy! 
At least you recognized the pressure signs at the end. I have worked up loads for the 115 DTAC with 4350 and RL22, and RL22 edges out the 4350 for accuracy...in my rifle.

These were all 100 gr 40 gr 4895.
The necked down 308 brass sometimes pinches the bullet.
That last primer pocket reminds me of a girl I met outside Ft Leonard Wood........
Back on topic. I've had good luck with H4350 in the 243 as well.
105's work well with H4350, H1000, and Retumbo. I shot 105's with H1000 with 26" barrel, and speed was 3000 avg. Chopped the barrel to 21" and speed was 2885 avg. Shot the same, just a little slower.
