with the limited availability of H4350 I'm looking for alternate powders. 243cal 90/100gr bullets seeking most consistant velosity's with some speed (95gr around 2950fps) what about superformance (I can get that)
From the burn rate chart:
109. Winchester 760
110. Hodgdon H414
111. VihtaVuori N150
112. Accurate Arms 2700
113. IMR, Co IMR 4350
114. Hodgdon H4350
115. Alliant Reloder 17
116. Accurate Arms 4350
117. NORMA 204
118. Hodgdon HYBRID 100V
119. VihtaVuori N550

My most accurate most consistent powders with the .243 (I've tested 10 different ones!) 80/87 gr bullets H414. Reloder 19 with just about any bullet over 80 grains.
N560
I've had good results with reloader 17.
Ramshot hunter is another that many find works well. Not many retailers carry it though
RL17 is good for at least 100fps over H4350 with the same load, and have always found you can load hotter which ends up being 200fps faster.Originally Posted by stomp442

RUMs are like woman in Stiletto heals, you know they are going to put you in the poor house, but that has never stopped anyone from pursuing them.
I've been trading off between IMR 4350 & AA4350.
In my 30.06 & 25.06 the loads work out the same.
I grab whatever is available at the time.
'Scuse me while I whip this out...!
I run rl17 in my 243s with 95 and 105gr bullets
I use RL 17 in my 6x47 Lapua and am running around 3050 fps with 105 amax out of a 30 Brux barrel. Accuracy is exceptional. I ran Ramshot Hunter in my .243 Win but it is difficult to find. I have actually used Hunter in a number of cartridges and have had very good results in each. I think now I would try RL 17 or Superformance due to availability of Hunter. I use Superformance in my 300 RCM and my 22-250 specialty pistols.
More shooting, less typing.
IMR 4350 has always given me top accuracy in the .243 but there are several powders that work well in it.
It's better to shoot for the moon and hit the fencepost than to shoot for the fencepost and hit the ground!
IMR 4451 has been working great for me. And it's available.
I use RLs 15 and 19 in my 243. When I started w/ the RLs 17 was not yet available. They are good powders. For load data see Alliants site. Lots of data.
