Nice boomstick Woody, are the newer 45-90's twisted tight enough to stabilize 500+ grain bullets?
If so that 500 gr Jerry Dean flat nosed greaser would be the do all end all for any N.A. critter in that rifle.
Thanks pard the twist/OAL would be questionable for 500 gr bullets as this Miroku Winchester is twisted 1:20 same as their 45/70 offering. I've done some homework on other forums where guys say they have stabilized bullets up to around 450. RCBS makes a 405 that casts heavy to about 425 which apparently shoots well and stabilizes in this new '86.
I contacted Tom at Accurate molds and inquired about cutting me a custom 465 FN which will come in several thousands below OAL and should feed OK.. but first I'll load a few of my PH Lyman 457121's which weigh 475 respectfully,crimp over the last band for OAL and see if they stabilize.
Half the fun of owning these guns is playing Dr Frankenstein in your own labooritory...
