[QUOTE="bruno t, post: 1042558, member: 78680"] I did a test with magpro and my 270wsm in my select grade kimber, 72 grains magpro moly coated and 150 grain berger, at 70 degrees I got 3,216 fps. I then put 5 rounds in the freezer for 30 min. I have a range 20feet out the backdoor. The velocity dropped to 3,130 so almost 100 fps less! Just a test.. So it didn't have a chance to warm up outside.. I'm still dumbfounded, on how I'm getting 3,040 fps, with the 180 grain woodleigh bullets and magpro.. [/QUOTE]
