No, .270 wsm and .270 winchester are not the same.
no they both are different.
DO NOT ATTEMPT TO DO THIS!!!!!!!!!!!! DANGER!!!!!!!!!!!!!!!!!!!! UNSAFE!!!!!!!!!!!!!!!!!!
Yes, you need to use large rifle magnum primers.
The .270 is a necked down 30-06. .270 WSM is a necked down .300 WSM. The 270 WSM is faster than the .270, and has a shorter case.
Each rifle will pattern differently. The perfect ammo loading for one may not work for another.
Have a gunsmith verify the exact 270 chambering. <><><> Agree. The standard .270 cannot fire the .270 WSM, and vice versa.
3+1 Meaning 3 in the magazine and 1 in the chamber.
Winchester Short Magnum
You will have to get as many different brands and bullet weights as you can afford and shoot them. Most rifles will show a marked preference for a certain brand/bullet weight.
Definitely Not !!
no!!!!!!!
No. The WSM stands for Winchester Short Magnum. They are not interchangeable.
