does any one know how thick the jackets are on the 300gr. offerings from remington,winchester,barnes O,hornady,sierra,and nosler? I know that the jacket on the nosler varies from front to back. I think this info was on MT but i forgot to save it........thanks in advance....bearit..

Bearit,
I don't know in terms of .Ks, but I do know it's paper thin. I've retreaved(sp?) a few JHPs and JSPs from the berm and examined the peeled back jackets. I could bend the jacketing in my fingers.

Most of the jacket's are very thin with .025 being the standard on .300 grainer's.Barnes is alittle different being all copper.The good thing is Hawk bullet's where you can order jacket thickness.There standard is .025 for the 45-70 and also for the .454.I don't understand.If you had a .035 Jacket to withstand and penetrate as the 45-70 can do,it would be a good load.A 300 with a .035 jacket would do or kill anything on this continent.

Just my opinion.

Barn's put's a little thicker jacket if i remmber right
so that would make it about .040
the rest run about .030 on the 300 grain bullet's
With these it's a bit rough to gett the max out of the mushroom on deer
A bit thiner wall would be good but most bullet compony's shoot for the middle of the road that way thay hit both side's
Deer Bear Elk Boar etc
Some use a tapperd wall jacket .025 -.050

Pottsy
but thay work out just fine
