My second edition hornady reloading manual does not show load data for the interbond bullet. Of course, hornady's response was to buy the newer edition. Does anyone have load data on the 180 gr interbond in the 300 win mag? Can I use the load data listed for the standard spitzers?

I have been using 72 gr H 4831 for 3043 fps.

Hey Terry,

Are those loads listed as max in the new hornady manual? My old manual lists 74.3 gr as max load with h-4831. I am trying to find out what the max load is with RL-22 and the 180 gr interbond?

75.5gr of RL-22 works well in my sendero. Interbonds, accubonds and partitions all do well with this load in my rifle. I use an OAL of 3.35".

You can use the old data for the IB. They do not separate them and show one set of data for all of their 180 grain bullets in the new manual. Work your way up from the starting load and quit when you get signs of pressure. From my own experience R22 and H1000 gave me the best combination of accuracy and velocity.

Thanks for the responses. I already have a load worked up with a 180 gr partition and 75.5 grains of RL-22. I think I will try to work up to this load with the interbond.

I've been using 77.0 g of H4831 with the 180 g. Accubond in two 300Win Mags with good accruacy and velocity of 3050 fps out of a 26" tube

I don't think my load is "max", but seems to kill whatever it hits quite well.

Just finished load development for a buddy.
89gr. of IMR7828, Fed215, 180gr. IB's
chronied from his 26" bbl@ 3250fps.

With 89gr of 7828 an a 180 bullet, you are on the road to an explosion. That is about 10 gr over IMRs max with a 300 Win Mag.

+1 to that.
