Might move out of My GOEX 2 F mindset  This fcor my 40/65 CPA, 440 gr bullet.  Dealer has the following options

The range of Goex including Cartridge and Express

Two new ones they are stocking are Schuetzen about the same price as Goex  & Swiss lot more expensive

Are Schuetzen and Swiss worth considering ?

Boats,

When I shot allot of BP matches, I loaded a duplex load and it shot extremely clean and accurate.

I used 4F as the duplex, about 5 to 10 grains will make Goex do you a fine job.
Of course lessen your 2F charge the amount of 4 F you use.

I would shoot a whole 50 shot match plus sighters and did not clean between relays even in low humidity days. Down to 35% rel hum.
It is worth a try.

Thanks that links up something I remembered about Schuetzen, not a particularly good powder.  So Swiss may be worth the extra money. Might lay in a can or so when I buy a supply of 2 F Goex

Duplex with 4 F is interesting, only thing is I am about committed to wiping between shots so clean burn is not a big issue.  Will keep that tip in my back pocket

Thanks all

kik shoots very well for me in my 40/65 and 40/82 98% as well as swiss.  i use it for sil matches.  art

Thanks Strider  have about half the 5lbs of Goex left. Goex is my long time standard powder, mostly because it's always available.  Just thinking ahead. Will be passing Winchester Va on the way to Columbia Schuetzen match first Friday in August. Probably pick up some more Goex and a few cans of Swiss just to see.

I hear good things about KIK, no matter if I can't buy it.

SSS agree powder is probably the cheapest part of the equation.   Unfortunately my choices are limited by availability and for that reason alone have always used Goex

I am going to try some Swiss and will take your advice on the granulation.  2 F is my normal, some say 1 1/2 F.  This 40/65 with the bullet seated out to engage the rifling will only hold 51 grs of Goex 2 F drop tubed.  Perhaps going to 3 F will get a bit more powder and velocity out of the load.  Bullet is a heavy one needs all the powder it can get.

Be a month or so before I can get a couple cans of Swiss let you guys know the results.

I have always used 2F (Swiss) in my guns up to an including the 50-90 with good results but after getting SPG's primer tried the 1.5F. Only difference I saw was slightly softer fouling but otherwise the same. As I recall though SPG's book recommends 2F for the 50-70 while 1.5F is recommended for the 45-70...

There are 3 brands of BP that the charcoal is made from Alder, the best wood for BP including the glucose in the branches which is the 'engine' for BP
* Schuetzen, straight Alder from subcontracted charcoal.  In 2009, their "sporting powder" sold as Wano in Europe & Schuetzen in the US was reformulated.  Velocity increase was 8 -10 percent better and fouling control improved also.
Wano doesn't make F grade which stands for sporting powder?  I beg to differ ...  (You need to Login or Register to view media files and links);
* KIK, Alder Buckthorn - unknown in house or subcontracted
* Swiss, Alder Buckthron - in house ricked for 3 years and then in house produced charcoal with 65% creosote maintained
The other brands: Goex uses Yellow Maple and Diamondback uses bamboo for charcoal

Since I started shooting BPCR, I have shot every powder brand & grades on the market plus 1973 Meteor (it is Curtis's & Harvey's formulation) and old DuPont with lots ranging from the '50's to the 70's

OK, what is my Go To powder?  The March 2009 lot of KIK for velocity, fouling control while maintaining accuracy.  Here is the results of a 50 consecutive shot string using this powder ... (You need to Login or Register to view media files and links)
My 2nd favorite is Goex Cartridge for multiple caliber consistency even though I am not a fan of other Goex grades and their Express - 'hyped to be moist burning powder' - so much for PR and is also discontinued 

New kid on the block is Goex's Olde E' (Olde Eynsford) being tested by a handful of serious BPCR shooters including myself.  We haven't determined how Minden makes the powder but it is better than 100fps faster than Swiss and KIK, with varied results for fouling control by caliber.  My comparisons with several calibers has KIK still as my Go T0
