Hi All,

I did a search for load data for my new CZ safari classic in 505 Gibbs and could not find any.

The only bullets I could track down where some woodleigh 600 grain ppsp. I found some loaddata that uses RL15 and darcon filler. I was hoping that someone here could pst some data or PM me with data for these rounds that does not use a filler.

I am waiting for my Hornady 525 grain dangerous game soild and expanding bullets to come in but they are back ordered.

Is RL-15 not a little too fast for such a large case??? I tend to use RL-19 and RL-22 in my 416 rigby with great results.

I have also ordered 200 custom Hawk bullets in the 525 grain weight for me to play with and maybe take this years moose with?
Mr Gibbs

Welcome to AH...

You have a fine rifle, however as you are finding...as specialized caliber are made your choices become limited.
I you go to Barnes and check 505 Gibbs you will find data for there 525 gr bullet. and powder.

or type in 505 gibbs reloading data you will find a few pages to view through
The rifle seems to digest the filler rounds with out a problem.

I was hoping that someone here would have load data for the 600 grain bullets with a slow powder like rl25 rl22 or retubo?

Wonder load from a disk has info for the Gibbs.
I looked in my A-Square reloading book and it also does not have any loads for the 505 other than the 525g bullet!
I also have the CZ in 505 - great shooting rifle.

Well, sir, I am mighty impressed with the quality of the shell cordovan belt. I have several pairs of shoes that are shell cordovan, but had balked at paying over half that price for just a belt. Wouldn't be surprised if this belt doesn't last the rest of my life--for its color application. It sure is a universe removed from the cheaply constructed yet expensive stuff being put out there. Worth the price I paid.
