In response to the OP, I wouldn't build a 284 win on less than at least a 2.95" box length. A Wyatt's box on a Rem would be ok. Mine is on a Model 70 SA and will handle up to 3.1" COL. The wife shoots a 7-08ai on a Rem 700 SA with a Wyatt's box, but it really would work fine with a standard box. The bullet of choice for her gun is a 120 gr TTSX. Velocity out of her 24" barrel is within 50 fps of what I get out of my 23" 284 win. Both are plenty of gun. Both rock and are my #1 and #2 favorite cartridges period. Not sure which is which right now.
