RCBS Ammomaster chrono much high speed results?
I have test some loads the other day, and was impressed with the results... Too many impressed to be true!
I'm getting about 3550 fps from a 222rem, with a 53 grain barnes XLC (blue coated). It was a compressed load of vectan SP7 fired from a CZ 527 lux, with 23,5" sporter barrel.
Then, i get 3050 fps from a 243 with 105 amax. It was fired from a M98 sporter rifle, with 24" barrel and vectan tubal 7000 powder.
None of them has pressure signs.
The day was hot, with bright sun, but i set the chrono with the light diffusers and put it just a little bit close to me, to get under the range shadow. The speeds seem too high for me (it would be great if they are true!).
Have you ever experienced wrong results with an ammomaster? I'm doing something wrong?
