Now I've never tried to attain 3,200 FPS in this rifle.


I'm a short range meat hunter, not a long range target shooter so the current long range craze has not infected me.


I am not familiar with the 6.5 GAP, 6.5 GAP 4s or the 6.5 RSAUM .

Based on the above, I undestand that the 4S stands for "Super Secret Squirrel Schitz. Which leads me to question whether "B" claimed the naming rights!

Quien Sabe?


From the limited info I have it would be similar to a 300 SAUM necked down to 6.5

So From Sierra #5......

300 RSAUM........180 gr. bullet, Magpro min/max........64.9/70.1

300 WSM.............180 gr. bullet Magpro min/max.........67.7/76.9

Would seem the 6.5 WSM would have more powder capacity than a 6.5 RSAUM

I'm sure there are others here that have much more insight than I, as I'm JAPPFT
