Heavy versus lighter to 1000

[Dwh7271]

Maybe the wrong place to air this, if so feel free to delete or move.
I keep seeing quite a few folks wanting heavies for LR shooting and decided to do a run or two.
My reasoning was does the speed(velocity for purists :grin: ) you give up while adding a little recoil make enough difference to shoot the heavier bullets or not?(not judging just curiosity)
So I did a couple QL calcs and took them over to the JBM calculator.
I ran a Berger 130 VLD in .264 versus the 140 VLD to 1000 yards.
Here they are. Thoughts?

Yup - gotta do your homework for the 600+ yard ballistics.

Drop is figured and dealt with pretty easily.

Windage is the tough one - and in your example the windage for each bullet is very similar.

Nice comparison!

 

[Dwh7271]

Yeah, I thought it was interesting.
Figured I'd use a 10 mph full value and see the difference.

You might try comparing a 130 hybrid w G7 to say a Hornady 140 ELD-M G7 at those velocities.

Those are the go-to 6.5 bullets at our Gong range. Alot of guys are using the hybrid in semi autos and ELD in the bolt guns.

The 140 ELD has a real world G7 of .305 or better. At 2825 fps I am getting on at 1,000 yards w 28 3/4 MOA elevation. JBM predicts less than 72 inches windage.

JBM is very reliable as long as you include all the pertinent weather condition.

The ELD-M at 2880 fps would equal windage of the 130.

A 130 hybrid at 3,000 (which is a hot load in a CM), shows .287 G7. At my altitude, temp and humidity it would only need 25.5 MOA and 69 inches windage.

They are both supersonic to 1400 yards.

Your VLD's show super to 1500 but the Hornadys have a better reputation around here anyway for having accurate G7's.

The flatter shooting 130's at middle distance are handy for tough shots like an "egg shoot."
