    IMR 8208 XBR

    Re: IMR 8208 XBR did the ladder test this weekend and the only thing that seemed half way promising was the very bottom. 39-40.5 grains. Guess I will keep this powder for my 223 and stick with varget for 308. that kinda sucks but stick with what works I guess.

    DIY Mil-Dot Master

    Re: DIY Mil-Dot Master If you can afford it? How can someone who needs this not afford it? If you have a weapon and mildot scope capable of shooting at something that needs to be ranged and practiced enough to be able to hit it I would guess you have spent a enough that a mildot master would...

    IMR 8208 XBR

    Re: IMR 8208 XBR Well I did 3 shot groups from Min-Max(imr website data)@ .5 gr increments. Nothing looked good. Every other powder I could easily pick the winner and work up/down .1 - .5 gr. They usually start big, get small and open up again. I emailed sierra and they said 8208 is...

    IMR 8208 XBR

    Re: IMR 8208 XBR So I tested it and it was not good. The groups did not match or beat 4064 and get this. I had three rounds out of ~60 that had delayed ignition. It was slow enough that I heard the firing pin strike immediately followed by the bang. Never had that happen before and called...

    Remington 700 ss 308 r5

    Re: Remington 700 ss 308 r5 I got mine on gunbroker last year for ~$1000 with shipping and FFL fee. I love it. I was disapointed with all factory ammo. Even Federal GMM. But handloads with 4064 average 1/2 MOA. Im hoping 8208 does even better.
