MY FRIEND HAS A LOAD I DO'NT KNOW THE GR'S OF POWDER IS .WHAT I DO KNOW IS ITS (BLC-2/150 GR BULLET/2200fps)THIS POWDER IS NOT LISTED IN MY BARNES BOOK.HE SAY'S THIS LOAD FLATTENS THE PRIMERS.THAT MIGHT BE TO HOT.
From Hornadys manual fourth edition
150 gr bullet
AA2250 max 32.3 grains
R12 Max 33.3 grains
IMR4895 not listed
Hogdon Data manual #25 lists IMR 4895 for the 150 grain bullet at 34 grains.
What does all that mean? why are they posting different maximums?
Valid questions for a new reloader.
Powder/bullet companies use different test guns/ sometimes different methods, and sometimes different bullet types.
IMO stay with the lowest max load listed, and start 10% below that.
Barnes bullets have different bore friction than other bullets. I checked with an earlier Barnes manual, and confirmed the data you posted, they have not changed it between manuals. There is no mistake likely.
However all prudent reloaders will tell you with good reason: DO NOT START WITH A MAX LOAD.
The 30-30 doesn't usually respond well to max loads anyway, groups tend to open. (My personal exception has been R12, it shoots quite well at max for me in a 1971 '94 Winchester Same load shoots like crap in two older guns)
The short answer, is that these loads are PROBABLY safe in your rifle. They are NOT "bolt gun" only loads.
