I purchased a new 16" 300 BLK barrel from BHW earlier this year and wanted to know if anyone is aware of any issues with baffle strikes occurring when shooting heavy subsonic round using a suppressor.
An experienced gunsmith I know advised me to use caution when shooting subsonic rounds using barrels with polygonal rifling since he said they typically do not grip the bullets as well as more traditional rifling.
He also said that a barrel with polygonal rifling would require a smaller bore diameter to correct for this issue.
Just wanted to hear any feedback from fellow users as well as BHW staff before I begin using a suppressor with my barrel.
Thank you

His statement is entirely false. I keep hearing this from people who have never used any polygonal rifling. Glocks are not true poly rifled. In closing I will say FIND a new gunsmith!!!!! |

If you have baffle strikes it is either misaligned or the bullets are not stabilizing right out of the muzzle. The true poly rifling works pretty well on what we shoot out of it and I am afraid I would have to respectfully disagree with the gentleman.
I know one fellow shooting a suppressed BLK with a BHW barrel. He is HAPPY!! LOL

Thank you both.
I know people have preferences for things such as rifling.
Typically my personal preference has been with polygonal rifling since I know firms such as HK and others have used them successfully for years.

If you handload I would recommend working up loads without a supressor attached to make sure the bullet stabilizes with your particular load before testing it with a supressor.

How would you go about doing this? You shoot it on paper and look for holes that are not round or blatantly keyholed. Use of a chronograph is very helpful to get the speeds up but not too fast.

Before I shoot anything suppressed I check the alignment of bore and suppressor. If you are using a Quick Detach "QD" device (flash hider or muzzle break) this also needs to be checked. Attach the suppressor to your barrel and use a wooden dowel or an alignment tool to check and make sure the device doesn't contact the suppressor. If you are using a QD device, some square off on the end of the barrel and some square off on the shoulder at the end of the threads. Lastly if using a QD, make sure you remove it occasionaly and clean the crown of the barrel, you will get carbon build up from some designs. Hope this helps.
