I would like recommendations for loading my 454 in a light load, what poders are best?  I have a lot of hard cast (nat bullet co) but poor design shape (not bear tooth) 300 gr bullets to shoot up.  I don't want to use 45 colt brass.  I want a clean powder and less recoil.  Maybe @ 1000 fps .

Jim,
 Hodgdon's no. 26 manual shows data for HS-6 and HS-7 for the 300gr. bullet. I've not used either in my .454 but have had excellent results with both in .38 special, .41 and .44 magnums. I have found that the published velocities for Hodgdon's loads are a bit exaggerated when chronographed.
300 grain bullet:
     Starting Loads                            Maximum Loads
Powder  Grs.  Vel.    CUP        Powder  Grs.  Vel.     CUP
HS-6      15.0  1084  31100    HS-6      19.0  1450  46200
HS-7      16.0  1111  33400    HS-7      22.0  1501  50200
                                                Hope this helps
                                                    Dave

I have tried Titegroup in 44 and 45 colt with good results.  I tried two loads in the 454 with a 255 swc bb. 9.5 grains didn't work well, but 10.5 seemed to tighten up fairly well around 4 inches at 75 yards, but I haven't been back to try again.  Hodgdon's lists 11.2 as a max for nosler 250 at 36000 cup.  I like this powder it seems to give good accuracy and very cost efficient as it sells for around ฝ - 15 per pound retail.
