rdish50,I loaded up some 100 gr. Nosler Partitions once.A friend of mine and myself were on a ridge when I saw a decent 8 pt. about 175 yds. away.I cut loose on him and he went down at the crack of the rifle.We went down to the creek saw blood ,But no deer.My friend looked up the other side of the ridge about 75 yds. away and put one through his ribs with a 30-06 .We got the deer but could only find the 06' holes( in and out).When we got home and was skinning him out I heard something hit the floor.Danged if it wasn' t the most perfectly mushroomed 100 gr. partition you ever saw.[]I could not believe it.I had hit him in the neck and the bullet did not exit. The bullet even weighed 100 grs.The partition did what it was supposed to do, ( remain intact)But Did not perform well for me.Go figure.Anyway I have yet to find one of the hornady' s to check out and they always leave a good fifty cent size exit hole.JMHO
