[QUOTE="Fiftydriver, post: 439602, member: 10"] ICANHITHIMMAN, "Whats a 7mm AM" Its one of my oldest wildcat chamberings. Basically a 338 Lapua, necked down to 7mm and fireformed to my sharper shoulder and min body taper design. About the biggest practical 7mm out there as far as performance goes. Performance wise, I am only offering the 7mm AM built on custom receivers designed for the 338 Lapua case size now. 140 gr Accubond can be pushed to around 3600 fps, 160 gr Accubond @ 3450 fps, 175 gr SMK @ 3400 fps and 180 gr Berger or 200 gr ULD RBBT @ 3250 to 3300 fps or as fast as they can be driven and still survive the launch speed. Accuracy of this chambering has been outstanding for such high performance. Powders of choice are Retumbo for 180 gr and under bullets. The ultraslow ball powders such as WC872, WC860 or H-US869 work great for the heavier bullets. "Why do you work so much" Do not like making my customers get mad at me for the LONG waits!!! LOL Can not complain about a good work load though. You guys have supported me very well and I greatly appreicate that more then I can tell you. [/QUOTE]
