I decided to hop into wildcats.
I was following the thread "MAGNUM PUNCH in an '06" by ELKAHOLIC and decided to try a Sherman Improved 270.
MAGNUM PUNCH in an '06
Rich sent me the reamer a couple weeks ago and I received my M700DBM back from my local smith who reamed it out to 270 Sherman Improved. This is the first rifle in this caliber.
The 270 Sherman Improved is based on the 6.5 Sherman Improved which is based on a 270 Winchester with the shoulder improved and moved forward for a gain in powder capacity of around 11%.
Here is a picture of the forming process:
First case being the parent 270 Winchester,
Then the case necked up to .308 and then necked back down to 270 to fit the Sherman chamber with a false shoulder,
and lastly the fireformed 270 Sherman case.
Here are 20 ready to load:
Now finding time to get to the range and do some load testing!!
