400 yard Six Pack Challenge attempt

[Swish]

My Impact has been shooting so well lately I thought I'd get up early this morning and see if I could beat the wind to the top of the mountain. If so I'd take a crack at Long_Shot's Six Pack Challenge. 

Out the door at 5:40am and to the spot by about 6:00. I made it before the wind but just barely and the calm didn't last long. I apologize for the terrible video quality as I had to cut and compress it so much to be able to post it. (Any tips on posting videos would be greatly appreciated.)

So this is most of my sad attempt at the Challenge at long range. I hope you guys get a kick out of it. IMHO I believe six for six can be done on a perfect day at 400 but time will tell.

I'd rather shoot those fresca than drink them too. Nice shooting

Thanks sonny. The key to getting fresca down is some gin with a splash of lime juice. Lol.

Very impressive shooting. How much drop do you have to compensate for at 400 yards? Did you have enough elevation adjustment in your scope turrets or did you use a tapered rail or no limit mounts? What caliber impact and pellet or slug were used?

Thanks igolfat8,

I make my own .217 slugs at 28.3 grains. I shoot them from a 700mm slug liner at 950 fps. I'm running a customized adjustable mount that I add 89 MOA from my 63 yard zero to reach 400 yards with. Compensating for about 31 feet according to Strelok.

Great shooting. Can you tell us how you get such a high BC out of the lightweight slugs that you make? Strelok says somewhere over 0.11+. The NSA 29 grain slugs are in the 0.09 range...

 

[igolfat8]

Thanks for the info. Are your slugs cast or swaged?

 

[Swish]

Thanks guys, I swage my slugs. I cant give an honest bc because I've never chrony'd them at long range.

I will say the bc I use in Strelok isn't quite as high as what Centercut came up with but he also doesn't know any of the other factors of my setup. At extreme range small things can make a big difference. 

I actually confirm my POIs before I cross reference them to Strelok and then fudge the numbers slightly if need be until everything matches perfectly out to 400+yards.

Then I'll go back out and shoot random in between yardages to confirm. Until confirmed they're just numbers. Just like 31 feet of compensation.
