2F vs 3F metering?
« on: March 06, 2007, 12:05:18 PM »
i finally made it out today to get some powder and 209s for my knight.  let me tell ya, i wasn't impressed with Bass Pro's selection :(  the only thing they had in loose T7 was 3F...so that's what i got.
anyway, since 3F is a finer powder, do i need to cut back a little more than 2F in a volume measure?
you'd think that there would be more 3F in a volume measured load due to grain size.......or am i overthinking here?

I think most here will tell you to cut back a little. But I dont think it will make much differents you will probably gain a few feet per sec I use 3f  and when I talked with NEF customer service they told me my gun was rated to 100grs reguardless of the F version. Cant speak for your gun might give them a call to be sure.

I used some 777 3f in my Knight Disc...Found out it didn't like more than 90grs, also had the problem with the crud ring...So much so that I had to lap the barrel to remove, I quit using it...I get better results with Pyrodex R-S (found it on sale at WalMart for $5)...But after I finish what I have I'll probably go back to Goex 3F...I can buy that at the distributor for $11.55 a pound and since I also have 2 flintlocks I need that anyway...

Bass Pro has Goex in Charlotte, but you have to ask for it because it has to be stored in a fireproof safe...only problem is they want about $20 a pound for....

If memory serves me right, you bought the Knight Disc...I believe its rated for 120 grains 777 loose....Look at the Knight website and get their number, I've called them a few times and was always able to get a real person on the line and they are very helpful....

My current loading is 90 grains of Pyrodex R-S or 90 grains Goex FFF and a 250 T-C Shockwave (or Hornady SST)....I have also had good groups with 100 grains and a 300 Barnes copper, just quit using because of their high cost and the SSTs are more aerodynamic, so I sight in 2 1/2 high at 100 and I'm 2 1/2 low at 150....

Thanks Flintlock. yes, i bought the DISC.
The Bass Pro here just opened up last week, and was fairly picked over.... believe it or not, i asked about the Goex, and they said that they weren't going to carry it right now ???
so i had my choice of Pyrodex P, T7 3F and Shockey Gold 2F.  Maybe i shoulda drove to cabelas? ;D

I'll try the T7 and see how it works with the 240gr cheapshots and 240gr XTPs i picked up, should have a range report up by sunday
