Does the 147 have the OAL taller than the 124 or 115? I bought a box of Win 147 HP to see if my gun will eat it. It was shooting fine til one time the round stopped on the feed ramp, an FTF. I pulled back the slide and let go and in it went. Out of a whole box I have this one. A fluke?

Also it shoot low to the POA like if the bullet's too heavy. I had a box of UMC 115 HPs I took along with and they shoot to the POA. Turned out the UMCs are really accurate and worth it for SD. I'll just have to get more of 'em for stock.

I reckon so.
Hey ...... we don't live in perfect don't ya know.

One out of a box? Wouldn't worry about it. Different weight bullets will shoot different, if it's your main carry, make sure the sights are right for whatever your carry ammo is.
