I have had a Winchester Apex for a little over a year now.

It's a decent shooting rifle, I'm just getting a little annoyed by all the blowback I get. I've tried switching primers but it doesn't seem to make much difference.

Cleaning the barrel is a breeze with this gun but the blowback behind the breech is what takes me a lot of time. I started wondering what things must look like behind my firing pin. Is this something I dare take apart to clean? Or is it one of those things that might be hard to get back together right?

I am starting to wonderif the 25 ACP conversion might be worthwhile. Has anyone here tried this with the Apex?

I guess the extra time cleaning up is no big deal I'm just a bit concerned about all that blowback messing things up in the firing pin area.
Any thoughts or suggestions are appreciated.
