1 powder for 243 and 270

[NewB7654]

I just got a 243 and want to reload for it as well. I like the Hornady 75g V-max. On my 270 I use Hornady 130g SST with H4831SC. I cant find any load data for that powder on the 243 so I'm wondering if anyone knows of a good powder (stable at all temp range like the 4831 is) that will give good results for both the 243 and the 270?
OR does anyone know if the 4831 will be a good load in my 243?

Also, I'm in the boonies, so can someone take a pic on the Hornady vol. 9 reloading data on the 243, 75g V-max and send it to me?

H4350 works great for both the 243 and 270.

100V will push the 87Vmax to 3325 in a straight 243 with ease. Very accurate with sd under 10 fps. The 130's in the 270 should produce top velocity with very good accuracy as well. I have the 130 sst loaded but have not tried it yet.

savagekindaguy - yes I know about that link. I started there 1st then came here.
Capt RB - the 100V is not extreme temp. stable, nor am I shooting an 87gr but thanks anyway.
dwm - the H4350 doesn't show any data for the 243. It's not even an option to view with 243, 75gr picked. Have you tried it? loads? speeds?

If you were shooting both light, medium, or heavy weight per caliber in each it would be easy. For example 100g and 150g. 4831, R19, R22, mrp, would all be good. In your case I think I would try H4350, as a compromise.

I 4895?

 

[jotrot]

for temp insensitive powder, give h4350 a try in both and even h4895.

good luck

H4350 if you really need an Extreme powder, if not then you have several other good options.

8th edition of Hornady manual lists 75 gr V-Max or HP with 42.9 gr H 4350 as the starting load at 3100 fps and max 46.7 gr at 3400 fps.

for 270 Win and 130 grain bullets 49.4 gr H 4350 gives 2700 fps and max is listed as 55.3 gr and 3000 fps.

The H4350 bottle lists both 243 and 270 load data, take a look at the bottle.

These loads are at the higher end of the load data, so work up to them.

47grains H4350 with a 70grain Nosler BT, very accurate in two 243s rifles I have

and

54.5grains H4350 with a 140grain Accubond, also very accurate in several rifles, I have shot this load in four 270s myself and load them for a friend of mine as hunting loads. My go to 270 hunting load.
