[QUOTE="Pdvdh, post: 282608, member: 4191"] Shot my 300 Win Mag over the chronographs recently. The muzzle velocity increased about 45 fps in this Lilja 25.5" long barrel after treatment with Gun Juice. 210 Berger VLDs now starting at 2967 fps. 74.0 gr IMR 7828 - Federal GM210M primers in Lapua 300 Win Mag brass. Shot my 7mm RM over the chronograph also. The muzzle velocity remained approximately the same in this Tikka T3 24 3/8" long barrel after treatment with Gun Juice. 168 Berger VLDs with a MV of 3055 fps. 74.8 gr Retumbo - Federal GM210M primers. There was a very substantial increase in MV with the 300 WM. Not much change in the 7mm RM. These were the very same cartridges I'd loaded and shot prior to treatment of the bore with Gun Juice. Dual chronograph setup. One an Oehler 33. One a PACT. I run two at a time with a separation of 6' on the Oehler skyscreens and 4' 6" on the PACT skyscreens. [/QUOTE]
