I loaded my 180 grain Nosler partitions today with 61 grains of
IMR 4831 in Federal fire formed cases and Winchester large rifle
primers. Chrony said that the first shot was 2902 FPS. Velocity ranged from
2858 to 2902, most shots in the 2875 area.
I also loaded some "condor loads" with 150 grain E-tip and 51 grains of
IMR 4320 for 2850 FPS. This is a LONG bullet. Accuracy was ok.
I will use this load on the California coast so that no condors are poisoned :-)
I have used 63 grains of IMR 4831 and Hornady spire points for 2965 FPS
and 62 grains of RE22 and the 165 Nosler partition in prior years.
The 61/IMR 4831 180 Nosler is a very accurate and mild kicking load.
These loads worked well in my rifle. Your friend needs to work up to them
in his rifle!
I will take these to Colorado in November for elk.
Sighted in 2+" high at 100 the 400 yard drop was 15".
Would I make a .30 Gibbs? No.
My rifle was re-chambered when purchased.
And once this barrel is gone the pre-64 action will become a .25/06.
In the mean time be I will be able to send a 180 grain bullet at 2900 FPS at sane pressure and good case life.
