    So here’s the deal. I’m having a 6.5x47 built right now and will be running the 140 hybrids.

    I’m looking at different powders
    I know H4350 is “The Best Powder Ever”
    Buuut I like to be different.

    I was looking at a burn rate chart and I think N540 would be a great option

    also interested in RL16 and RL 17

    I have all of these powders so I can try them all but just curious what alternatives there are to H4350.

    I’m also trying N540 in my 6br so it would be cool if it worked well in both but I’m probably not going to be that lucky.

    My luck has been with varget on 130 gr and lighter bullets and H4350 with the heavies. Although varget is very accurate with the heavies too...

    I am just like you in that I don't like following the norm but I just built my, getting older no more magnums, dream hunting rifle in 6.5x47L shooting 142 LR Accubonds.

    I went with a full case (slight compression) of H4350 in a rifle throated for the 140s and it went something like this. Bore sighted through the barrel at a 200 yard gong. Three shots and on center mass of the gong.
    Shot 3 consecutive 3 shot groups at 200 with the bullet touching the lands and they were all basically 1.25ish" groups. I was not upset with this and because this is a lighter sporting hunter I could have stopped there. I have no interest in the long range hunting so 500 and in is plenty.

    Went home and with the same load seated .020 off the lands I went back and gave the next 20 rounds a go. First 6 shots were at 100 yards in two 3 shot groups under a buddies labradar. First group was 2 touching and one a half inch out. Second group was 2 nearly touching and I yanked the 3rd shot for about a 1" group at best.
    2745fps average and 11fps spread.

    Went to 200 and shot two more 3 shot groups. One was about an inch and the other was about 3/4".

    Went straight to ringing steel with my last 8 rounds and never missed a plate to 600. I did miss my first round at 775.

    Gun was cleaned again and is now ready to roll. I do need to foul the barrel.

    None of the above is phenominal but it is very good for a sporter in my opinion. I probably could not shoot any better if I tried given the limitations of gun and glass. 15x Zeiss glass.

    My conclusion is in this case don't buck the system. Many before us kind of estsblished the groundwork for the 6.5x47 so all we have to do is go with it.

    I also shot 20 rounds of 140 berger hunting. I would say on average they shot better than the Accubonds but I don't have faith in them as a hunting bullet. I am not even sure why I bought them other than I did not expect the LRAB to be that accurate. Had I known I could get the accubonds to shoot so well I would not have bought the bergers for this scenario.

    Best of luck. Report back

    PP2000MR is not only faster, but most accurate for me. It gets a bad rap for temperature sensitivity, but I only shoot this at steel targets and have not observed accuracy issues on this basis.

    The RL16 is a great powder and easy to find, at the moment. Works great for the 140g
    RL16 will get you a little more fps than the H4350 and not hit pressure as soon either.
    The new VV N555 powder is advertised as an alternative to the H4350
    Might give that a try.

    Running 140 Hybrids, easy choice:
    Alliant Reloader 17 or Reload Swiss RS60 (the same stuff).

    Just about perfect burn rate.

    142 SMK and Varget worked for me at 1000.

    I've used cci 400 ,& 450, and not observed a difference in performance

    I bought a pound of RL16 to try and a keg very shortly thereafter. This stuff is a dream a Creedmoor. I'd think surely it's worth trying in the x47L.

    The usual criticism of PP2k I hear isn't temp sensitivity, but throat erosion. But it is pretty fast stuff.

    I agree.
    Find a friend with Quick Load, run several simulations, then go with Re-17.

    I’d say that RL15’s burn rate and consequent pressure curve is more suited to the 120 grain projectile types - the 123 Scenar being a good example. For the 140s you’d be pushing the pressures pretty high.

    I get crazy low Sd's with all the V-Vuori powder's Ive used and it does'nt seem to matter the caliber or bullets used within reason.
    I do use Berger's and Scenar's and some SMK's thrown in for good measure. However My 6.5x47 seem's to prefer Varget
    and the 140 Berger over all others Ive tried....I did want to get the N550 to work as well in it, but its just not quite as accurate as Varget.
    ( Close but not quite. )
