BTNagelRHINO monometal solids sticking in lands; options?
Hi, Bill!
Just ran into a little surprise with the .416 Solids. My .416 Rigby shows plenty of room to the lands with the "regular" RHINO moly-coateds, but even seated and crimped just below the collar on the monometals, the lands want to pull the bullet out! In other words, too close for comfort. Maximum casing length is 2.900" and my cases are all @ 2.885". I can get my full powder charge (100-grains H4831SC) under both bullet types, thus far. What I don't know is if it would be safe to trim the cases used for my Solids back to, oh say, 2.8770" and (of course) reduce the powder charge a little. Seated and crimped just under the collar again would clear the lands that way.
I'll copy this over to 'Big Bore' at AR and see what feedback I get. In the meantime, could you please send this feedback to Kobus et al. for us?
Thanx!

Mike375That would be OK.
Firing 458 Winchester ammo in a 458 Lott is an extreme version of what you are talking about.

BTNagelThanks for the response, guys. I may have to punt on the solids -- just glad to have a supply of RHINO's. Replies from Kobus re: my "problem" have been immediate and helpful. He suggests contacting the Big Bore Hunting Association of Southern Africa(
bigbore@mweb.co.za ) for advice and experience. RSA exposure indicates they function in a more free-wheeling way than we must in the litigious USA. Will take advice with a modicum of caution, usual with me, but I really like their openness and readiness to try new ideas. Reminds me of "the old us"?
MUCH obliged!

RatMotorBT,
Are the Rhinos you have monometal bullets? The 458 solids I had were filled from the back with a lead core. Mine had grooves in them as well.

GrandpasezIf you are that close to the lands, you should ream a little more freebore. can be done with a throater. All
smiths have them I think.That allows a margin of safety,
keeps pressure down a little, and makes load development
easier.Ed.

BTNagelRatMotor,
I received both molycoated "regular" RHINO's as well as monometal solids. The solids are grooved, like NorthForks, and have a collar up front like Trophy Bonded Sledgehammers.
