6mm-250 pet loads

[John from MN]

What speeds are people getting with 95-105 grain bullets? I've read the Hodgdon data, but the more info the better, IMO.
I have an 8 twist 6mm barrel with some life left in it and plenty of shank left to do a 6mm 22-250. Have the reamers and dies to make it work.

H4831-39.0 gr, br 2 primers, 30 inch barrel, 2809 ft per sec. shooting 40 gr H4831 tomorrow, will try to get you info. after.

H4831-40.0 gr, 2901 Ave. Varget-33.2 gr, 2994. 30 inch Krieger barrel. H4831 is probably too hot for summertime use. Today was in low 30's, will back off half a grain and see how that works. Varget primers say I could go higher, but .711 ten shot group at 100 yards and 20-40 mph gusts suggests maybe I'll stay at 33.2. YMMV.

NO! The 6mm-250 is just the 250 Savage necked down. The 6mm/22-250 is the 22-250 necked up. These are standard body length and base cartridge taper.

The 6mm International either Walker or Donaldson versions are different cartridges.

6mm Rem international has a longer neck.

This is the rifle and set of dies that came with it

So a 6mm-250 has a 26 deg shoulder and 6mm/22-250 has a 28 deg shoulder. Either your gunsmith etched the wrong nomenclature on the bbl or you are using incorrect dies for that specific chamber.

You have died that dont make the chamber or gunsmith put wrong chamber on bbl.

You said a mouthful there, friend.
