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

@DPT job done. Thread in something common (1/2*20 unf) believe dpt can do threading but may be easiest getting somewhere nearby to do it.

Have had a few of their suppressors and happy with them, much better quality than other cheaper brands I have used in the past, but confess I am not a supressor conassuire. Depends what rifle will be used for, always a choice between cost, effectiveness and weight

DPT second that. Dont get a cheapy. Send it direct to get it threaded.

I wouldn't ever choose that size for a 7mm barrel, especially a hammer forged/ button rifled barrel.
I'd suggest at least a 14mm thread in this instance.

Hmmm have above thread on the 308 and no problems with 50 or so rounds, any reason for a different thread? Could do with losing a few inches off he barrel as it doesn't fit in the car wih the supressor on...

1/2x20 on a 308 barrel is a bit too narrow. If you get the measurement from the deepest cut in the thread to the centre x2 (IE the minor diameter of the deepest part of the cut for the thread) and subtract the bore size for 30cal then the amount of metal between the projectile in the barrel and the outside is very very thin. Minor diameter is 11.14mm- 7.62mm bore size = 3.52mm, divided by two (half each side) = a barrel wall thickness of 1.76mm on each side of the bullet......

I am not an engineer so if my measurements are not 100%exact I apologise, but it does illustrate the point for a larger diameter thread.

Most of the gunsmiths I have spoken too now recommend 9/16ths for a 30cal.
