6x47L powder choices for 100gr sierra

[Dusty Stevens]

What have you found to be the go-to powder for this ctg? And do you think a 10tw barrel will stabilize a 100gr gameking?

 

[Jason Boersma]

The powder for it is H4350 and try federal match primers with it.

rel 17

RL17 will give you 150fps more velocity with the same accuracy. With 140gr I'm at about 88% case capacity. You may get to a slightly compressed load with 100gr, but you will be "amazed" at the velocity. A longer barrel (26in min) will take best advantage of the extended pressure pulse of this powder (well documented on this website). And RL17 is a very "friendly" powder to work with. No scary pressure spikes as you approach max loads.

I believe he is asking about the 6mmx47 not the 6.5x47 so the 100 grainers would be the heavier longer ones.

A friend has a Tikka 243win 10twist and shoots the Sierra 100gr SPBT Gamekings very well.

If you're planning on shooting lighter bullets as well as the 100gr GK, a 10twist would be ideal.
But...
If you're not going to shoot bullets lighter than 85gr, I would get a 8 twist so I could use 105+ grainers for long range work.

H4350 behind 105 Bergers is all I've shot, itty bitty groups.
