Thread: Advice on suppressor for Howa 1500 7mm-08

DPT for me and never looked back.
Great product and great service: Read the information that comes with it!!!

I will say it again: Read the information that comes with it!!!

There are two issues around this.
The first one as Tim mentions is that wall thickness becomes marginal with a half inch thread. This probably isn't a huge safety issue as muzzle exit pressure is way down on peak pressure but it's not clever to run anything close to the edge.

The other issue is a potential accuracy one, especially with button rifled barrels. Swaging the rifling into a barrel leaves (outward directed) stress in the area around the bore and if you cut away too much of the surrounding diameter, there is the definite risk the bore dimensions will grow at the muzzle. A belled outlet will never be helpful for accuracy.

So what would be the largest thread that can be cut on a 14,5 mm .308 barrel? Was thinking to get my Savage LWH threaded in the future.
I also see the Kimber Adirondack muzzle brake .308 Win. comes in 7/16 x 28 from the factory. @6x47

My "advisor" says a 13x1 would be probably the best you could do as you need to have some shoulder to pull up on. This thread would be way better than a 1/2-20 as the metric one would take less meat out with the lesser threading depth.

Hmmm ok cheers folks, it's behaving itself at the moment (3shots cloverleafing at 100m with factory ammo) but will bear it in mind if I change it

I have a sonic suppressor on my 7-08, works for me, nothing to compare it to but it sure quietens it down

Thanks for all the advice guys. Think I might get a DPT and give it a go for a while. The modular design sounds pretty nifty to me.

Makes for easy cleaning

I'm a MAE fan, they're Auckland based, they certainly know their stuff, and have a varity of options for you.
You're best to talk to them, yes they are heavier than many but you get top notch gear, I run them on all my rifles .22 - .300 Magnum and certainly won't be changing anytime soon.
Worth checking them out, Gary and Geoff are both very knowledgable and will make to suit your rifle and needs.

Cheers C
