1st stab at load development with this combo and 100gr HDY. tarted wit 10 gr, looks decent. Anyone have anything with this combo that will dial it in any better?

Thanks

With 115 gr lead, I found (IMR)4227 had two accuracy peaks. One around 9 gr and another accuracy peak around 12 grs. The higher loads burned cleaner but damaged targets. The 9 ish gr load leaves powder and ash behind but does not stay in barrel long. I have to clean the chamber more often with 4227 but the barrel build up is not a problem in my marlin.

H4227 or IMR4227?

I used 10 grains of IMR 4227 with a Sierra 90 grain bullet and it shot very well in my marlin. Had to bump to 11 grains when I tried the 100 grain Horn. Both shot very well and had very little site adjustment.
