Now Pop, I'm going to give you this load and trust you will not use this bullet on game /ubbthreads/images/graemlins/grin.gif.
85 gr Retumbo under the 240 SMK gives me 2850 fps. I could gain another 100-150 fps but this load shoots under .25 MOA EVERY DAY.

Is 3000 fps feasible? What is the BC of this torpedo?

3000 fps is gonna be iffy. Mine has 30" 4 groove Lilja. I could get to 3000 fps w/this setup but my best accuracy was @ the 2850 fps mark. I'm not sure what a guy could get w/a 26" bbl. The bc is .711. Of course as the bullet slows, Sierra shows it to degrade a little.
I wouldn't use those SMKs for hunting either /ubbthreads/images/graemlins/blush.gif /ubbthreads/images/graemlins/grin.gif!

It would seem to me that with our 26" factory tubes, that 2800-2850 is all we could expect with decent accuracy probly at the 2800fps mark. Even at that speed at 500 yards, I obviously would not want to be a deer in my sights. I think the 220g smk, is actually little better route, but thats just my opinon. BC is .629 and you can get it going 3000fps. I have shot them out to 1150 yards and was happy with them. I have not tried the 240g smk simply because you have to buy them at 500 at a time. I dont exactly have $200 to try on a box of bullets.

My gun likes 89 grains of Retumbo for around 2850 from a 26" barrel. Extremely accurate.
My favorite was 99 grains of H870 when it was available for about 2980 but had decided to reduce that to 98 for hot weather use which would put it around 2950. But then the powder went away. This load was also extremely accurate.
US869 is on the way though....

Where are the wind drift #s?

The wind is different maybe 2-3 inches, in favor of one or the other. Cant remember, but I dont think thats anything to worry about. No one can judge the wind within 2-3 inches at that distance anyways. You would think the bigger heavier would buck the wind much better then that, but it really doesn't. I have done the comparisons and looked at them to know that its only a couple inches between the 2 bullets at 1000 yards. Dont know what it is at 1500 yards. THose 2 bullets are very close ballistically to each other. I guess the only way to see what one you want to shoot is to let your rifle decide which one it likes better.

These are what I get, 5 inches of wind in favor of the 240. These BC's don't line up with anybody elses but it works for my program and drop charts.
Each drop in bullet weight, decreases MOA needed and energy and gives a little more error to the wind. Unless ya'll stop messing around and buy a nice WEATHERBY /ubbthreads/images/graemlins/smile.gif Then everything just gets easier.

I've looked @ this before. Just kinda pokin' @ ya for leavin' out the most important factor.
I'd like to add that I looked @ this after I found a load w/the 240 that shoots one ragged hole. I really wish I had gone w/the 220 over the 240 for cost and availability. Hopefully the 210 wildcats I have coming will be THE ANSWER.
We'll see!!!!
