Less then two weeks ago we brought you the news that Kel-Tec had Suspended the Production of the PMR-30 due to keyholeing issues with the barrel's 1:16 twist. On Monday we received an update:
They were originally testing a 1:12 and a 1:9 twist to solve the problem of stabilizing the bullet, but ended up compromising on a 1:11 twist.PMR-30 Status Update V05-23-2011The new barrels are finished and we’ve resumed normal PMR-30 shipments. The new twist rate of the barrels has eliminated the potential for key-holing. It ended up coming out to a 1:11 twist.
IMPORTANT: If your PMR-30 is experiencing key-holing (the bullet tumbles end over end rather than spiraling), please notify us via phone: 321-631-0068 321-631-0068 321-631-0068 (use the Accessory Sales option), or contact our Office Manager via email: email@example.com to arrange for a replacement barrel to be sent out to you. There is no charge and we do not require the original barrel.
The easiest way to see if your barrel is affected is to shoot at paper targets and see if the bullets are hitting the paper sideways. You should be able to see quite clearly if the bullet is hitting abnormally. If the holes look normal then your barrel is unaffected. It is up to the shooter to follow safe shooting practices during this process. Use eye and ear protection at all times and do not point the firearm at anything you do not intend to shoot.
