Thread: 6.5CM bullet performance

Probably no real issue with the terminal performance of the 143ELDX but I see no advantage either.
143gn ELDX. 41gn 2209 2575fps. 200m zero is 64mm high at 100m. 300m 26.6cm low. 2157 energy. 500m 151cm low. 1894 energy.
130gn SGK 43gn 2209 2780fps. 200 zero is 54mm high at 100. 300m 23.7cm low. 2228 energy. 500m 138.7cm low 1898 energy.

That 41gns of 2209 behind the 143ELDX did not produce a very flash group in the Sauer but to be fair that was only 1 x 3 shot group. It seemed to group ok with 40gns of 2209 but I was not really happy with the low velocity, 2540fps from memory. I have been playing around with Superformance and managed 2714fps with 45gns in my Bergara HMR 6.5CM so maybe I will try that load in the Sauer.

Give Hodgdon superprofrmance a good good you should be able to load around 46-47 grn behind the 143 ELDX

I ran a ladder on the 143ELDX with superformance in My Bergara 6.5CM HMR. Starline brass and federal 210 small rifle primers. I went from 44gn to 47gn. 45 seemed to be the sweetspot after that I was getting significant primer cratering and the groups started to open up. But to be fair this was in the Bregara and not the Sauer, however the Sauer seems to have quite tight chamber and a shorter throat so I doubt I could comfortably push them harder than I already have.

Just to draw out the significance of this :
There is a big difference between MV of 2575 and 2780.
2500’s might be OK for target but is really sub par for hunting, where some flatness of shooting is helpful.
The TV is getting down where bullets dont open up.
At 2540 like one has mentioned you need to use a rangefinder and holdover on anything past 100m.
If you stoke up a Grendel it can do as well as that…

That's pretty much my point. The 41gn 2209 is 1 grain under book max for the 143 ELDX and the 43gn of 2209 with the 130gn is book max using the hornady reloading app and using the data for H4350 which is ADI2209. Both projectiles might carry a similar energy to the 500m mark but the flat shooting advantage od the 130gn makes it a clear choice. I know some will claim they can get higher velocities than mentioned here but I think there will always be a velocity advantage to the 130gn vs the 143gn Projectile, there has to be.
