A 40 degree neck Ackley Roberts any day. I get an easy 3500fps with 87 grain pills and 2950 with 120s; NO pressure signs. There is however an issue of 87 and 100 grainers breaking up on medium deer sized animals shot under 200 yards, leaving a fist sized entry wound. The 120s I use are Nosler Partitions.

Rifle used is a Carl Gustaf with a 26" Shilen #4 profile. Powder is ADI 2209.
