I have been shooting the 6xc for over 6 years. I have tried many many different powders. What I have learned is day in day out H43350 is THE powder for the 6xc. That is not to say that others won't work but H4350 is the best.

thanks soo much

if you could guesstimate .......... about what will max charge be

 

[wc872]

Every barrel is different so they all have different maximum charges. I have had a "slow" lot 8 pounder of H4350 that took 39.9grs. DO NOT TRY THAT LOAD! before starting at 37.0 & working up. I think that you will find a sweet spot around 38.2grs. I have also had barrels that showed HIGH pressure at 37.7 grs. My advice is to start at 37.0 & go up .5 gr at a time. Load only one round of each charge. Shoot them at 200 yards & I think that you will find that three of the rounds will by touching. Take the middle charge weight of the three that clustered together & simply load'em & shoot'em.
If this is your first 6xc I predict it will be the first of many. Barrel life for winning groups will be slightly over 2,800 rounds.

Probably about 40 grs. depending on your barrel. I am using Broughton barrels on both of my 6 xc's and i am able to use more powder without pressure than most people's guns in 6xc. The 105 hybrid has been consistent for me than the 115's.

That is great barrel life, 2800 rounds!! My 243ai is only expected to have a barrel life of 800-1200 rounds I have heard. I deferently want to build one of these once my 243 goes south.

That's great advice......I've been loading and shooting a long time and was not aware of that approach. Thanks so much

I have some 105s and 115s and hoping the 115s will work the best....we'll see.
Thanks

I have to give kudos and thanks to everyone on this forum.

I posted the exact same question at the same time on another forum (you know the one)...and did not get a single response

speaks to the quality of the people that are on LRH
thank you all so much

I settled on 39.3 of H4350 for a 108 Berger. Gets me around 3010 fps out of a 28" tube.
