Xp .400 200 gr
CF .400 230 gr
These are the two i'm interested in using

They aren't legal for hunting Big Game in South Dakota.

They are legal for long range gong hunting which is what i want them for .

The controlled fracturing will be better for long range shooting over the XP.

sabotloader, thanks for the testing of the 1:28. Think I'll need to try them in my Knight.

Thanks Mike
Am I right in assuming that 210 or 215 grains in brass will be all a 1-28 twist can handle?

Lee, I am not really sure as I really not the ballistician that you are and certainly can not even come close to Lehigh Dave.

At one point I really feared that this new 200 XP might not shoot from a 1-28 and I think Tom had some concerns also. If I remember correctly Lehigh Dave had indicated 1-28 but he had also said that about the 40x200 CF. Myself and others found that we were able to shoot that one from a 1-30 without a problem.

The two bullets are the same length so it seems to me that it is something to do with the different configurations on the nose of the bullet.

What would be really cool is if some one could see the both bullets in flight cutting the air and see what pattern the might create.

This doesn't mean a thing and may be a figment of my imagination but when I shoot a CF bullet, even with ear plugs, I can hear a definite 'hiss' as the bullet travels and a definite 'click' when it hits a clay pigeon. With the XP, I do not recall the 'hiss' and more of a 'thump' when it hits the bird. But the greater 'thump' could be the wet clay immediately behind the bird.

I want to return to the farm early next week, again with the Elite 50, and shoot some extended ranges - 150 to 200 and see what the bullet might be doing at those ranges. If it achieves stability form a 1-28 at a hundred how long will it maintain stability? I guess I could ask Dave that one.

Dave has, I am sure, computed BC mathematically - again something I do not know for sure but I think Tom or I, at some point, is going to shoot it through two chromos to get a real life number.

I guess we all expect the BC to be lower than the CF bullet but the way it is shooting, I am not so sure. I have begun to wonder it the design of the nose in conjunction with the aero dynamic design of the cavitation cavities might not lessen the drag compared to the deep open hollow point. Again something I do not know - I am just a shooter/hunter.

Thanks for the report Sabot. That is some very good shooting and that bullet looks "nasty". I'm not sure how the expansion on this bullet would be. I'd really like to see that at a couple different velocities.
Although I never hit the shoulder, the deer I have taken with a .40 cal 200 gr XTP have all been pass throughs so I'm not sure these would provide any additional benefit to me.

That's my thinking also. At 65 yards a .40/200 XTP over 85 grains GOEX blew through the chest of a 110 lb. doe, spraying blood and lung matter on a bush ten feet behind her. That's pretty much all I need a bullet to do.
