Finally got to the range to sight-in the C-more sight that I replaced recently. You can see from the video that the new 9mm Major CFE Pistol rounds I loaded is much more consistent and accurate. Excited to finish off my HS-6 loads and start using the CFE rounds.
Recently picked up Rainier Ballistics as a sponsor and got a load of 124gr RN plated bullets to try out in my Open Gun. Brought it out to the range today to test and I was very disappointed. They didn’t perform as expected but found out the problem later when I went home.
here’s the two groups of 5 shots that I made comparing Rainier 124gr RNs to Montana Gold 124gr CMJ Jacketed bullets. These are shot with 8.2gr Hodgdon HS-6, Winchester SRP, Various once fired brass at 20 yards.
as you can see, the Montana Gold bullets group really nicely whereas the Rainier’s are all over the place, if they actually hit. I only managed to get 3 out of 5 shots on paper.
I’ve also measured the sizes of the plated bullets vs jacketed and the MG Jacketed bullets (out of ten) come in at .355 consistently while Rainer’s come in mostly at .3545.
I consulted my panel of experts and was asked to pull the bullet to see if I’ve over crimped the bullets. Jacketed bullets have a harder shell and are more resistant to crimping, while plated is a soft coating and very easy to dent.
here’s how the bullet looks like after pulling it, as you can see, severe dent from over crimping.
I readjusted my crimp die and now manage to crimp the bullet without marring the bullet.
I’m now looking forward to testing this new batch of ammo to see if I can get as good a group as the Montana Gold jacketed bullets. I’ll be a happy camper if it works!
Ever since I started shooting USPSA Open, I told myself that I’ll push myself really hard and to my limits in the hope of doing two things, 1) go faster physically, 2) get used to the speed so I’ll start seeing my sights and getting my hits at that speed.
and it’s working.
I’ve been giving up a lot of points going really fast and for this latest match at Renton Fish and Game club, I decided to slow down a tad and see what happens. Lo-and-behold, I won my division. Granted none of the GMs and Masters were shooting, but I think apart from the first stage where I was confused as to what I was seeing in my sights, and one stage where I failed to count my rounds (stage 3), I did pretty well.
Here’s the video :
I’ll keep on pressing myself to go faster physically so I can get used to being fast and get my hits. that’s my theory and since it’s working, I’ll keep doing it.
Just noticed a very small detail that was added to the M&P that you don’t typically see in a pistol and definitely not in a polymer one. They’ve added a slight crown to the barrel which is widely known to improve accuracy. Here’s a description of what a barrel crown is and it’s purpose :
The primary purpose of a firearm muzzle crown is to provide propellant gases a resistance free path away from all parts of the projectile as it exits the bore of the barrel. The secondary purpose is to protect the bore from damage caused by misuse. The third purpose is for good looks which is always achieved when the primary purpose is satisfied.
Good Job Smith and Wesson! I’m liking this gun more and more.
