Maximum point blank range 0-400

Sorry more a generic statement to the 70-75gn class of mono bullets. PVA Seneca; Cayuga; Badlands bullets all in the high .4 to .5+ g1 bc. When you run the math they can if pushed fast enough they can keep that MPBR 6" diameter to 400 w/o bleeding off at 350. Kind of a silly endeavor, but a fun one. Most my presssure dogs hang up outside of 400, give you time to range etc. Inside of 400 you can generally tell they are plenty close, and I want to just hold center, flop. Yes - this can be done with a vanilla 22-250 w/50's at 4000fps to 350… and the calorie burn to get 50yds more is really not worth the return on investment… but, for whatever reason I'm hooked on trying to make it happen!

Practicality has nothing to do with this endeavour haha. The .22-250 would be so boring. Only big 22 I've ever played with was a .220 swift. It was fussy haha.

Flattest shooting round I've loaded to date with a actually my .300 win mag with a 120 Barnes tac tx at 4050 fps. It's a .300 win load that shoots flatter than my .257 weatherby…so far. The 75 grain hammer could change that….I have the nerve to hope for 4400

To do your 6" MPBR how high will you be sighted @ 100"?

If I do a 1.9 sight height. 3" MPBR 'radius'. .49 bc at 3800. :

Roughly a 2" high at 100. 3" high at 200. 0" at 330. 3"low at 385.

A higher sight height like 2.75 will allow you push that curve out another 15yds.

Haha right. I've missed plenty over estimating and sending it high…

Yep that's why I'd look to do things a bit differently. Until the mid 80's or so I tried it this way. I missed (over the top) so many yotes you just wouldn't believe it.

Find a scope to make it work better and forget the MPBR thingy......

Well, I think it still has its place. Most my educated dogs hang up and sit down well out side of 400. I range and dial. When several dogs surprise you, in that hard to estimate range of 300-400, and you want to just hold fur and send it - I like having the flat shooters. I've done 88gn 223's at 2600, and didn't like having to range outside 200. Great in the wind, and consistent for long pokes, but causes misses you wouldn't have with a flat shooter. Also when they're running, or when you catch one in a stubble field from the truck- no time to range. So best of both worlds flat, and buck the wind - 70-80's 3400+!
