Some basic data.
Barnes 160 gr X S, Win296 17.8g, OAL: 2.000 Nosler 180 BallTip, Win296 17.5g, OAL: 2.160 Barnes 185 XLC, H4227 17.5g, OAL: 2.160 CombTech 200 BST, Win296 16.8g, OAL: 2.200 Hornady 225 SST, Win296, 13.8g, OAL: 2.105 Sierra 250 SMK, Reloder 7 14.5g, OAL: 2.200 Hawk 300 RN, Reloder 7, 12.6g, OAL: 2.075 |
| I have a 16" barrel Pac Nor chambered by Marty Weems in 338 Specter. It looks like it will come down to RL 7 or RL10 for the 300gr SMK for subsonic loads with suppressor attached. You have to shoot like it is a rimfire because of the time the bullet is in the barrel. JP |

I don't know whether or not you plan to use a suppressor, but here's a data point. I asked Marty whether a regular 9mm suppressor would work and he said that in his experience, yes. I have to defer to him GENERALLY, but mine does not work. I have a YHM 9mm suppressor and it moves point of aim at least 12 inches and opens 338 groups from 1" or better at 87 yards to no better than 7 inches. I have seen no evidence of baffle strike, but something is dreadfully wrong with my set-up.
I am waiting for Marty to get me a 16-18 inch barrel in 338 and after that is built I will probably get a custom-made suppressor from these guys: http://www.awcsystech.com/thundertrap.html |

I am using a SWR Trident and it works without issue, several others are using similar set ups, including the guys at SWR.... see if somehow you can test it with a different suppressor, I would be curious to see how that would affect it. Baffle strike would be difficult to imagine as the 9mm suppressor will have enough clearance for a .355 bullet and you are firing a .338 bullet, so plenty of room. It could be that the baffle geometry of the YHM somehow is causing an issue? Steve at ADCO is using a YHM 9mm on an 8.5" barrel 338 Spectre with good results, not sure if he has shot for groups.

As I said, I will probably just go with a custom-made AWC once I get another barrel from you. Also, I want to emphasize that I think this is primarily a result of some anomoly with the YHM suppressor I have. Again, the 338 barrel shoots great until you hang the can off the end of it. Lee |
