DF.....one thing I've found out about CEB's they love speed and you can use lighter weight bullet that will penetrate better than the heavy weight for caliber cup-cores...

In 300 BO no problem with 100gr. CEB to get 2400 fps out of a 16" barrel with W 296 and drop 300 lb. black bears....see it done twice....

Special Rifle Zone in Michigan you can use 35 caliber or larger maximum 1.8" straight wall case....I use a 450 Bushmaster and 160 gr. CEB on whitetails get 2700fps in a 20" barrel and a case full of Lil'Gun 5 DRT bucks....no problem putting 3 shots into 3" at 300 yards with a AR-15, Savage and a Ruger American...

CEB's are the next generation of premium bullets and here to stay.....
