H4350 for a .243 Winchester?

I just recently started reloading and my dads old .243 was my test rifle. It shot everything about 1.5 to 2 MOA prior to hand loads. It is an old Savage 110E. I did bed the recoil lug and cleaned the hell out of it prior to loading.

I have run only H4350 with 100 grain Hornady BTSP. Started at minimum load and worked up in 0.3 increments. Got a half MOA group at 38.5 grains (this is a low powder charge but provided the best group for me) during my first loadings. All of my groups were MOA or better. These have proved consistent as they have continued to group between 0.35 MOA (best group) and 0.7 MOA over the last 3 months. Velocity is around 2850 but I don't have a chronograph so this is using multiple groups at multiple distances and doing the Math.

Because I don't have a chronograph I can't speak to SD and ES although I can say that they continue to hold 0.75 MOA out to 400 yards. This is as far as I can shoot at the range and I haven't gotten a chance to take it farther yet. I know this isn't benchrest caliber grouping but for an old hunting rifle off of bags and with me shooting it I have been happy.

My reloading mentor recommended H4350 as he had good results with it in the heavier bullet weights and it is readily available right now. It will also lend itself to other calibers I have been starting to reload such as .308 and 30-06.

Take it for what it is worth from a beginning reloader and beginner long range enthusiast but I think you will be able to find an accurate load.
 
When I first started loading bout 18 months ago, I started with 243 and been hooked ever since. My go to is RL26 for 105 hybrid with 210m shooting savage with proof barrel at 3054 fps with excellent results out to 1k yards. With 87 gr hornady and 95 gr Berger classic go with H4350. Best results with lapua brass.
 
I had good luck in a Savage Max 1 predator with H4831 SC with 95 grain Nosler BT and 95 grain Berger classic hunters. H4831 was awesome with very low es. H1000 was accurate at 100 with the same Berger's but es was as good. A buddy uses IMR 4350 and swears by it in 243 win.
 
morning, 4320 is a powder that is forgotten. I use this
powder for 6mm bullets upto 95gr. above that
RL-15, W760, H414, and the best 4831. I look
at my powder chart. I load 3rounds of various
powders to check for accuracy. I never have liked
4350 when these powders r available.
bullet weight and design play in on any variables.
I have a 243AI and 6mmAI. the 95grvld in the
6mm and 77gr. in the 243. the 6mm caliber is one
of my favorites for any kind of hunting in TX.

I don't have any 4320 and RL15 as I've always tended to use slower powders for everything. I'll keep those two in mind though. Interesting. ;)
 
forgot to mention 4064

Morning to you, sir! Seen 4064 mentioned quite a bit for the lighter bullets. Berger lists the max load for 87 grain bullet only having a case fill of 84%. Seems like that wouldn't produce optimum results, but a lot of shooters sure seem to like that powder with the .243.
 
Talked with my father who shot .243 for 30+ years and reloaded for competition. He swears by 4064. Ive never tried it but think I might give it a whirl.
 
I've shot around a thousand rounds of 95 grain vld's with H4350 and 300 105 grain vld's. I have been very pleased. Accuracy and velocity are both great.
