6.5 Bobcat anyone?

[JudeinPa]

here is a new wildcat I am designing. A 6.5 Bobcat. It is based on the .243 WSSM necked up and with my changes in the case dimensions.

It estimates on my Q/L as more velocity than a 6.5-06 and less powder!

here is another view of the same cartridge.

Should be interesting Jude. What do you calculate case capacity in g of water to be?

 

[snake river rufus]

No dimensions? Just how are you changing the case?

 

[JudeinPa]

Dan, the H2o capacity is 57.8 grains.

Yes, there are no dimensions posted. Don't want anyone coping them until I make a reamer. I could post a pic of the chamber too.

Do you anticipate better ballistics than the 264 win mag?

Sounds like a good cartridge.

 

[JudeinPa]

Running the Data on my Q/L it will get 100fps better velocity with 4.5gr. less powder. Using a Nosler 120gr B.T. and 49.7gr RL-19, 3,100fps.

My 6.5-06 using 54.2gr RL-19, 3,009fps.

To match a 264 Win Mag (82 grains of H2o), you are better off going with a 6.5 WSM.

Thanks Jude...good stuff.
