Thought this might be helpful info for the new .224 swagers:
I called the Berger folks to find out the recommended weight ranges for the various length J4 Jacket offerings and they provided me with the following info:
.224 - .600 length - 30, 35, and 40 gr bullets
.224 - .705 length - 50 and 52 grain bullets
.224 - .740 length - 55 grain bullets
.224 - .800 length - 60, 62 and 64 grain bullets
.224 - .930 length - 70 and 73 grain bullets
.224 - 1.000 length - 75 grain bullets
.224 - 1.060 length - 80 grain bullets
.224 - 1.125 length - 90 grain bullets
Hopefully, this will get me (us) in the ball park when I (we) need to order jackets. I'm sure there are options to buying every size and more than one length can be adapted to different weight boolits - i.e. lead tip and hollow point....
Over to the experts for commentary....
