When 'magna port' first came out I though about stuff getting into the bore of my rifle and how to ever keep it out? It gave me the creeps. What about when it rains and then freezes?
Such holes in a barrel have to increase the blast back to your ears.
As BobinNH suggested above perhaps the gun kicks too much?
I got my Kimber Montana in 270 WSM out and have it up here by the computer. I know that it jumps some in my hands even in 270 WSM but the kick does not bother me. If it shot a heavier 8mm bullet it may well kick too much.
The WSM's barrel here is .560" at the muzzle and too thin for the holes in it if it were a .323" bore.
I suggest that you buy another rifle that kicks less and then sell that one if you like the new one.
All guns should be locked up when not in use!

The recoil is not to much for me at all. Hell I shoot my 358STA off the bench and the 325wsm is no ware near that in terms of recoil. But if porting can help with barrel jump in the Montana I think it could be a good idea...

Yes,
Do the Magna Port!
When you wrote: " All this talk about recoil and barrle jump has got me thinking about Mag-na-porting my 325wsm. Whats the negative about doing this? "
I thought you were talking about recoil and barrel jump but its barrle jump.
Now I know why ................

Randy-seriously if you magnaport it you'll wonder why you didn't do it earlier.
Its good stuff I'm telling you.

Agree with Dober;IMO it's the best choice if a guy wants to go that way.
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

I know this is a really old thread, but I'm considering a Kimber Montana and also considering magna porting. How much difference in noise did you notice? Is the gun quite a bit louder? Thanks

Hello Ryan, I never got the Mag-na-porting done because the Kimber Montana barrel was to thin in 325WSM...

Thanks. Those who have magna ported smaller calibers, have you noticed an increase in noise level?

Interesting. Magnaports website says a min wall thickness of .13". So, you'd have to have 0.583" at the muzzle for them to do it to a 325wsm. What does the kimber .325 measure? Ryan

Not a smaler caliber but had a 300wby mag done and the noise was fine as long as you are behind the gun. If to the side it is verry painful.

I'm a little ashamed to admit it, but I have only shot it once. Working out of town sucks, but at least saved per diem has bought me some cool toys (that I can't play with!).

I have a range pretty close as well, but I'm out of town for all but about four days a month. No bueno.

back to the mag-na-porting since its just ported and not breaked(in other words the holes are not angled back towards the shooter) why do so many say its so much louder, i cant figure out how it would be any louder than a barrel cut to the length of the edge of the first hole from the chamber end of the barrel....the gas isnt going at any different direction than out of a normal barrel, lil more is just directed straight up.....
ive got a Marlin Guide Gun thats got the older ported barrel and i hear so many others who have them claim cause of the porting they are loud....i dont think its any louder than any other short barreled rifle....is it loud with normal loads? yep but its cause of the 18 inch barrel(16 with the start of the ports) instead of the 22 inch every one is used to not cause of the porting
