I went out today and ran some pills through my Lane Scorpion all Ti can. First I ran it through the 264LBC/6.5G. 20" BHW barrel 1/8 twist. Much quieter. I had hoped to use a DB meter I have but it does not have a fast enough response. It was hearing safe, ears did not ring after shooting 5 rounds through. First shot had a slight FR POP. Bullet impacted 4" low 4" right. Next four moved left 1" and up 1/2" all touching. This will be easily corrected if I cannot find a load it likes with and without the can. This was from the 50yd line and raining. Did not feel like walking the full 100yds in the rain today. I know I'm a wimp.
Then onto the 458. Used my Rock River upper 16" barrel. It was definitely quieter, though not as quiet as the 264. It was probably just above hearing safe though my ears did not ring. Using the HDY 300JHP they were impacting about 3 feet low and a foot to the right. They were right on the last time I took it out. Maybe a 2" spread but not that far off. It took the full 20 rounds I had to bring it on tgt and seemed a bit erratic. The 300gnrs have not been my most accurate round. I did not bring any others today as I was just comparing sound levels.
Over all the can did what it was supposed to do. It quieted things down to what I would say is just a bit quieter than a 22lr pistol. My ears ring with the 22 but did not with either suppressed guns. It was at a different frequency though, the 458 kind of roars in comparison, while the 264 has more crack. The 264 is moving a bit faster. I will try different bullets, probably the Barnes 300gn TTSX as it is my most accurate. Next is the 325 FTX. Now to work up some subs and see how they run. Will be pushing the 400gn Remington's and the 500gn HDY's. Has to wait until work dies down a bit. 2 shows in April and I have nothing finished.
