Home Forums Hunting & Shooting Gunsmithing 300 Win Mag Problem....? HELP!!!

Ok just checking!

Remember the old song "Battle of New Orleans" by Johnny Horton?
We fired our cannon til the barrel melted down. Then we grabbed an alligator and we fought another round. We filled his head with cannon balls then powdered his behind, and when we touched the powder off the gator lost his mind.

Everything was going pretty good until your buddy damn near "melted the barrel down." Now it's been cleaning, multiple barrels, more than one stock, scopes/mounts?, and different loads? I don't know what to tell you, but I'll be interested, once you figure it out (if you figure it out), what shooting it so much/hot had to do with it. That said, unless something else happened that you missed, shooting it so hot seems to be the thing that started all the trouble.

I just loaded up 180 SST / 68.0 / 69.0 / & 70.0 grs of H4350, 9 1/2 rem primers, seated to 3.440 which is .030 off lands... surely something here will work... I sure hope it's the loads.... we'll see tomorrow... if not... it will be scope and mount changing time. I've NEVER had a challenge like this before...WOW.

If it works... I'll be so happy that I will give all you helpful Guys a three night, four day vacation in the Keys...LOL.

Dan I know you have said the scope, rings and base is fine but they are the only thing you haven't changed. Maybe it's time to do that or at least take a different scope in different rings with you to mount on the gun if it still isn't preforming like it should.

Change the barrel nut,it's possible ya'll stretched it during the "how fast and hot session" and it's not quite getting tight enough to actually hold the barrel as solid as it needs to be.

Sell it.
Buy a .30-06.

Sell it??????/ That is nothing more than screwing over someone that doesn't know better. That's lying, deceptive, and dishonest in every way... remind me to never buy anything from you...LOL.

i GOT IT.... so far so good. After installing the 4 th barrel... and a plastic stock, it still didn't shoot good with 150 gr bullets....so... I loaded up some 180 SST bullets with H4831SC, at 68.0, 69,0 and 70,0 grs of powder... and they started grouping. The 69.0 grouped consistantly around 1/2"... which is AWESOME... now i need to replace the laminated pretty stock to see if it still groups. Thanks Guys for your helpful suggestions.

Good for you! Ive gotta ask. 300WIN with a 150gr? Why? 180s are IMO a way better choice and it's not a surprise it shot them well.

I used 180 gr bullets... I couldn't get the 150's to group well

I'm asking why did you try 150s? Seems way to light in a 300WIN. Was there a specific reason you tried 150s? Either way glad you hopefully found an answer to the problem.

The owner was shooting 150's when I got it, so we tried to stay with them... and in the beginning I had some 150's shooting pretty good... but it went south. The 150's put every deer in the dirt when he shot them... hopefully these 180's will do the same.

Could there be a crack in the laminated stock?
Delamination?

The 180s will be fine on deer. Good luck!

I just shot it with the laminated stock and it shoots good now... so now I'm not sure if the whole problem was just the reloads and the barrel... it doesn't matter now since it shoots 3/4 " at the moment... and it's going back to my buddy.... Praise the Lord....LOL. thanks Guys for all your help. May Jesus Bless You All.... Dan
