Does anybody remember IMR 8208 XBR anymore? well I bought a bottle before the release of LVR powder. If I remember correctly the IMR 8208 XBR was the powder to try before LVR was available.
Well I just got around to loading with it for the 308ME. I uses the HDY. #8 book and it shows data for the IMR 8208 XBR 160gr. FTX 308ME bullet. WLR. HDY. cases. Start @ 35.0gr. max @ 37.7gr Okay Made 5 each 35.0gr., 36,0gr, 37.0gr, 37.5gr., 37.7gr.[]
At max. charge 37.7gr. print velocity is 2500fps out of a 308MX 22" barrel so it should be at 30 fps for every additional inch of barrel length. So my 308XLR according to print I should be in the 2560fps area.
Sorry but I don't have a chronograph yet but it is on my wish list. My concern at the moment is accuracy and pressure.
Can I get any thoughts or experience on this load since this load data is offered in print from Hodgdon too.
