I just got a used Sendero 300 RUM with 20 rounds down the tube. The previous owner shot a qurter sized group @ 350 yds with factory ammo out of it and laso says it's very pleasant to shoot. Just need to get the rail base and rings now to get my NSX mounted on it.
Wil be testing numerous bullets and loads through it to get the best combo.
Just took delivery on a full custom Edge and have a .257 barrel enroute for a 25-06AI or 25-284. Really want to build something suppressed like a .338 Whisper. Need to find out if the .338 Federal will work well sub-sonic with 300 gr. Matchkings to make it duel purpose.
