Yes, I would be very interested to hear that too. I have used the 350 RN in my 460 Bee at 2800 fps and they didn't come apart at those speeds on Black Bear so no idea why they would 1000 fps slower
Large buck zebra was shot just behind the shoulder at approx 65 yards. The bullet struck a rib and apparently came apart and failed to penetrate beyond the first lung. Tracked for a mile before I was able shoot him in the back of the head at 35 yards and kill him. Large warthog at 45 yards with hit on point of shoulder. Bullet fragmented but did break the onside shoulder however the pig went a quarter mile before it fell over. Large bull eland at 10 yards. Just behind the shoulder, both PH and tracker saw impact. Did not recover animal. Killed several smaller antelope (deer sized) between 65 and 125 yards and did not have a single bullet exit.
In real world ballistics we do see lead fragmentation all the time. A lot of times it happens when impact velocity is very high and the lead is pushed to a work hardened state on impact. It's more prone to happen with lead alloys which most rifle bullet cores are made from but we also see it on handgun bullets when they strike heavy bone ( or windshield glass) at the hi-end of their operational velocity. The Interlocks have a pre-skived jacket and the skiving is curved to just below the radius of the ogive. The round nose bullet doesn't appear to have that pre-skived jacket. I can only conjecture that that pre-skiving caused really rapid expansion and possible breakup and failures to penetrate. Again the round nose 350 grain Hornady does not have that skiving and appears to be solid all the way to the exposed lead nose. I think the 350 RN is probably a better big game bullet than the Interlock. I think it was my mistake by pushing the Interlocks at a velocity that they were never intended to go.
Didn't realise you were shooting spire point Interlocks. Never shot game with those. As to 2800 fps, that was out of a 460 Weatherby. Interesting thing is, despite all the flame, roar and recoil, they don't kill one bit better than the 45-70 does. It is the hole that kills, not the speed. It was what truly convinced me that ft pounds of energy is a totally useless way of estimating effective killing power. If it was millions of Bison would still be alive, and a 54 calbre muzzle loader would have never killed a thing, let alone a spear or arrow.

Which 300gn are you referring to?
Use Fed 215 or Winchester magnum primers and crimp the bullet. Large bore rifles tend to leave unburned powder and powder grains otherwise.
