Just got back from the second testing session. This time shot moly coated 160 accubonds from the longer barreled 7 Rem Mag. (30")
Didn't have any loads to compare as this bullet hasn't been shot before. Decided to compare RL-25 and Power Pro 4000 MR.
Conditions were 90-93 degrees. Bullets were seated approx .030" into rifling. Neck sized/neck turned win brass, 215 match primer. Two shots fired with each powder increment.
Power Pro 4000 MR
62 gr 3015 3015
63 gr 3043 3060
64 gr 3098 3114 most accurate with two shots cutting each other
65 gr 3122 3141
66 3148 3163 hint of bolt lift/pressure
RL-25
70 gr 3096 3077
71 gr 3120 3131
73 gr 3235 3261
74 gr 3320 3294 hint of bolt lift/pressure
That pretty much concludes any testing with the 7 rem mags and Power Pro 4000 MR.
MR stands for magnum rifle. Sure would like to know which magnum rifle!!! Getting a bit over 3100 fps with a 30" barrel doesn't seem very impressive to me.
Now deciding what rifle to test next.
