How Much FFFG ?
During the storm last week I cast some .45 cal. 200gr R.E.A.L. conical bullets for my TC Hawken, but I have no load data for this type and weight of bullet.
Any help would be appreciated. TIA, Rich |

Whatever works best. Start around 50 grains and fire a few rounds and move up to 55 then 60 and keep going until you get the best groups.

Thanks Hawg , in my limited experience with BP I've only used a patched ball. Now if we could get some decent weather maybe I can make some smoke this weekend.
Thanks again, Rich |

Have a 45 same as you. Although according to the owners manual 2FFG is preferred for 200 gr. Maxi use.
Start 80 Max 110 Recommended 90 There is a published articular some where's that states what the equivalent reduction factor is. 3 FFFg measure _vs_ a known 2FFg charge. Although without that knowledge at hand I {assume} a 10% reduction of 3 FFFg would be acceptable. |

Thanks for bringing that to my attention, I don't have the original owner's manual and the on-line version has no load data. As always I'll start low and proceed with caution.
Thanks again, Rich |

rule of thumb 45 and smaller FFFg
50 and larger FFg As above start at 40 45 grains work up till you get best groups then go 5 more grains ( stay at or below maximum. If your 5 over load accuracy falls off then the last was your max accurate load. also if you have a fast twist rate, you may not get an accurate load with the conicals |

Either or is good.

ConRich I think that Sure Shot has given you some pretty good information and is basically stating that you can get equal or better performance and use less propellant, using FFFG. I don't think you want to split hairs but is by chance you have a Chrono, you will be able to make a more accurate comparison. ..... At any rate, range-time is in order ...... Be Safe !!!

I now have everything needed to make smoke, just waiting for the weather to break, we just got our 4th nor-easter in a month.
Thanks to all who have taken time to answer all my questions, I'll post the results of my range trip soon as the snow melts. Rich |
