POP - Quick Load: 243 Win/Nosler 6mm Solid Base/H4831SC

[smokey262]

Pop,

Can you please post the quick load report for what appears to be the holy grail for my 243 Savage? After trying numerous loads the Nosler 6mm Solid Base bullets over a near max charge of H4831SC has me jumping for joy. I am curious what QL says vs. what the chrony and my eyes tell me.

Thanks

I have gotten 3250 fps with 100 grainers and IMR 7828 before from a 24" barrel.

Just FYI tidbit. :lol:

 

[smokey262]

Thanks Pop. Yup, they are 100 grains

I had an average in the upper 2800's with 42.5 gr. at a COL of 2.655" and a 22" barrel. Not a trace of pressure sign and was thinking about giving it a touch more to reach 3000 fps if possible with good accuracy.

Was going to get another pound of the H4831SC. Maybe see of Sportsmans has the 7828 sitting there too just for the heck of it

I ran it at 2.655" Coal for you. Interesting playing with quickload, check out the diff from 2.8" to 2.655".

If that doesn't shoot to your liking, give RL-22 a try. Works great in my 243 on the 95-100 grainers. IMR4350 works great in mine in the 85 grain range.
