Hi everyone, thanks for all the great feedback.
I've measured the COAL for the bullet to hit the rifling, this however was longer than what my magazine can accommodate. I therefore seated the bullet so it just clears the magazine, and developed my load for that. I chose to user Varget...really just because it's popular. The choice to use the Hornady ELD-X 143gn was for it's availability, and also because my research suggest that it's the heaviest bullet my 1 in 8 barrel can stabilize. The heavier the bullet, the less effect from wind. No??
I was getting consistent Sub MOA with my setup, confirmed with paper targets at 100,200 and 300m. This accuracy is theoretically sufficient to hit the 10"x10" metal plate consistently at 800m. As a side note, I would need to buy a lottery ticket if I can get my gun to shoot sub 0.5 MOA. Mine is a budget heavy barrel Remington 783, MSRP around $500. 0.75-1 MOA consistently I'll say is a big A+ for Remington.
My theory is that the higher speed would be more forgiving and allow more error to remain on target. 100fps extra get's me 19 in less in drop out at 800m, that sounds quite significant to me.
It sounds like my best bet to get higher speed is to select a faster powder as oppose to adding more Varget. Hornady's book have the following powders which according to their data can output 150-200fps more speed. You guys have any suggestions for reloading newbies? On a budget here, don't really want to spend $300+ on various powders and have them collect dust haha. Also the temperature out here can swing between -40C to 30C.
