45 70 seating depth issue

bartman45

Using the bullet in split neck case and placing in chamber, I should be able to seat @ 2.9" overall. If I go beyond 2.65", I cannot chamber the round. Sharps/Pedersoli, no crimp on case. Would a taper crimp die take care of this, or how do I do it??? Thanks for any help...

Meant to say taper seating die.....

I would bump one gently into the mouth of the sizing die (decapping pin removed, of course) and see if that put enough taper crimp on it to allow a long loaded round to chamber.

A friend found his .40-65 would take a 2.90" round yesterday and apparently has room for 2.945".


Why would you want to say taper seating die?
A separate taper crimp die would be the right way to go. Combining taper crimp and seating seldom works out well.

So what bullet are you using? You might consider doing a chamber cast on the longish side to get a look at the lead into the rifleing. You might also consider a bullet breach seating tool to incert the bullet into the bore then chamber a case with card wad on top to hold the powder in place.

I don't have all my books here. From the "Lyman Centennial Journal 1878-1978" loading data for the Lyman #1 Ruger in 45-70.

322gr #457122 2.610" 366gr #457124 2.723" 420gr #457193 2.680"
426GR #457102 2.680" 451GR #457106 2.650" 464GR #457125 2.878"
a 5OOgr Hornady Round Nose is listed at 2.930
