Best powder for 223 rem, 75gr BTHP Match, Starline

[Rob01]

Why not?

Why not what? Switch to VV?

 

[Drop Port]

Ditch the 75 gr bullets and go with Sierra 77 gr in front of 24.0 to 24.5 of Varget.

Why not?

If y’all were taking in person, you would realise that you are agreeing. lol!

I wasn’t arguing but just trying to clarify if there was a question.

77 MK are designed for AR15's they have a BC of .362 where a hornady 75 BTHP
has a BC of .395.

 

[Rob01]

And the 75 ELD-M has a BC or .467 and why I mentioned if he was changing he should change to the ELD.

I been running 22.0 of N133 in a Starline case with a CCI400 for years.
From a bench with a bipod and rear bag at 200 yards Berger 75 will
shoot 5 into .380 and Hornady 75 BTHP will shoot 5 into .506.

BC's Don't count for much if the bullets doesn't shoot!

Lol, Service Rifle shooters look for any powder requiring between 24 to 25 grains and a 75-77gr bullet and go shoot. Load development not necessary until you can clean a 200y rapid target.

Switch to Berger 73's and load with CC450 and Varget or CFE223.

I've been shooting N133 in 223 with 75 and 77. Not the highest velocity but the ES is very low.

 

[JB10]

I use cfe223 in an AR that i shoot the 75 bthp with good accuracy. In one of my bolt rifles with the 73 eldm i use varget and shhots great.

 

[jnr88]

TAC, Varget and N140. All work well and the ball powders meter easily. JMO

 

[Cfshooter]

So many powders able, I like N140 and Varget, they are good for almost all 223 needs.

I would recommend picking any primer but the Winchesters though.

Extruded, not ball or flake powder, too.

I use a lot of Winchester primers.

I just checked my notes and was getting 2743 FPS, 22.0 N133 and a 75 out of a 20" AR-15. A quick 5 shots over a Garmin yielded single digit ES, 3 shots were identical FPS.

 

[whatsupdoc]

BC's Don't count for much if the bullets doesn't shoot!

The point is why shoot a bullet specifically designed for an AR in a bolt action
when there are so many other better bullets available.

Leverloution (sp) is a ball, good velocity and accuracy. Staball match, same. TAC is good but a bit faster burning.. google powder burn rate chart
