I got my guide gun for Christmas. I noticed it has a 13.5" length of pull. That's fine, I have multiple rifles like that. The 300 grain federal powershok's I've been feeding it don't kick that bad. I don't have to worry about my thumb hitting my face. I'm starting to get into bigger loads (starting with Hornady leverevolution 325 grain) and I'm worried about my thumb hitting my face during recoil. I'm going to put a burris fastfire on it, so I don't need to worry about eye relief. 1. I prefer a 14" length of pull on shotguns. If a 14" shotgun fits me, will 14" work on my guide gun? 2. What is the recoil like with the leverevolution ammo? 3. HOW GOOD IS THE 1895 MARLIN PACHMAYR PRE-FIT PAD? 4. HOW LONG WOULD IT TAKE FOR ME TO GRIND A LIMBSAVER PAD TO FIT MY RIFLE just using normal sandpaper?
