Re: 300 RUM Early Pressure Signs?
I took these loads out to the range again today and her are the results...
180 E-Tip, pressure signs at 98.5 gr of Retumbo. No signs at 98 gr with 3440 fps.
180 E-Tip, ran through my string up to and including 98 gr of H1000. No pressure signs. 3400 Plus.
200 AB, ran through my string up to and including 97 gr of Retumbo. No pressure signs. 3270 fps.
200 AB, ran through my string up to and including 94 gr of H1000. No pressure signs. Less than 3200 fps, it was overcast and getting dark.
210 Bergers, ran through my string up to and including 93 gr of Retumbo. No pressure signs. 3130 fps.
Got some really good velocities, My chrony was in the shade most of the time and intermitant sun and clouds. Usually low light means low readings in my chrony... but hard to say. Will being going back for more load development and chrony readings, hopefully on a better light day.
So it seems the early pressure signs wer due the the Gun Juice treatment, and possibly also high velocities today.
