Favorite powder to use with .243

[sigpro2022]

What is you favorite powder to use when using 100gr jacketed boat tail soft point in a .243?

I like IMR 4320 with Sierra 70 and 85 grain bullets.

H4831, been using it for 30 years, tried some others, keep coming back...

Mine really likes 70 gr Nosler's in front of 39gr of H380.

Another vote here for 4350....It is a very versatile powder that works well in .243.  I use Hodgdon rather than IMR

 

...and 25-06

...and 257 Roberts

...and 30-30

 

It is my rifle counterpart like Bullseye is for my handguns.

I do agree also with the 4350 I have loaded the .243 with it & it worked great just the H380 was more consistant for mine.

 

I also use 4350 for 7.62x54R, 7mm Rem Mag, 6.5 Jap, &.270 Win It is a very good powder to have around.

 

I use the H380 in .243 & 22-250 only at the moment.

IMR 4350

The best I've found for a 243 and 100 bullet.

I have always used H414.  I have a Remington 700 BDL that likes it along with Sierra bullets.  I shoot what the rifle likes ;-)

IMR 3031 and 105gr bullets.

It wasn't a boat tail but I loaded some with Sierra 100gr soft points using 35gr Accurate 4064 and out of 5 shots none of the rounds were more than 2fps apart from each other. It got dark before i could shoot groups but were about an inch just shooting through the chrony. I haven't made it back out to shoot groups with that load yet. IMR 4064 is about the same, just a hair hotter.
