Nope, the snapcap and gun will be fine, though I wouldn't let a plastic one bake in a chamber after a few mag dumps. A lot of us also use dummy rounds we load with no powder or primer.

Yea, Jerry knows a thing or two. Ox, I forgot to mention, that's good shooting for starting out, and those hits will tighten up fast with practice. Asking a friend to hide a snap cap in your mag can be quite revealing if you keep your eye on the front sight.

Regarding your question of how locked your arms should be, take a look at somebody like Jerry Miculek on youtube. Even with heavy recoiling handguns, the gun doesn't flip a lot because he's hanging on tight with wrists and elbows locked. I think the old 60/40 left/right grip ratio for a right handed shooter makes sense. But more important than any of that is not being rough on the trigger, which i still fight with after 10s of thousands of rounds.

And does it work in rain/snow?

Before I blasted my chrony, I used it quite a bit. Do you guys with the Lab Radar like it?

I told my friends that this is what I do to chronos that don't give me the numbers I want to see

Yup, put a 10mm out a 610 through the top corner. One remarkably bad shot. According to the previous shot, it was a 165 gr doing about 1200 fps.

Thanks, when things return to normal, and it's available, I'll check that one out.

Thanks. I wasn't very surprised the numbers on the boxes were optimistic out of a 4.2" barrel.

I chronographed some factory ammo I had today. This was all purchased in the last year or so. Hopefully this is useful for somebody. These are average velocities from 3-5 rounds.

Firearm: Ruger GP100 4.2"

Ammo

Buffalo Bore Heavy 357 180gr JHP
1285 fps, recoil was such that 20 rounds was plenty to shoot for me
Advertised velocity: 1500 fps

Federal Hydra-Shok 158gr JHP
1153 fps, this was comfortable for me
Advertised velocity: 1240 fps

Underwood 125gr JHP
1444 fps, also comfortable
Advertised velocity: 1700 fps

Sig 125gr FMJ
1259 fps, this was a light load and pleasant
Advertised velocity: 1450 fps

I thought it appeared to be very well made and easy to shoot. It's not really a 1911, but close enough that if you shoot 1911s well the Coonan is very familiar. Trigger was excellent. Recoil was less than my 10mm 10.4gr BlueDot 180gr hollow point load. Muzzle blast was way more.

I'd probably never buy one in .357 as it seemed to rip chunks out of the rims and make reloading for that gun a one time thing. The need of a tool to compress the mag spring to load mags isn't something I'd like.

It never jammed on any factory ammo and it was it's first trip to the range. Cool toy or hunting gun The owner knew someone who got it for him for under $1400, so I think he did well.

I've never seen a Coonan at the range. What's with the magazine tool? Something to deal with the rimmed cases?

I almost forgot, the most important part of this range report is a new shooter that loves it.

Also, PP clocks consistent velocities for me, and not just in 10mm. I used to shoot a lot of N340, but PP is significantly less expensive.

Ha! I kinda like the bang and flash from Power Pistol.

I was out at the range today with my G20 for the first time in about a month. A friend who was sort of a new shooter showed up and loved it. 8.5gr Power Pistol under 165gr Blue Bullets, nice volleyball size fireball. Also, I chronographed some Underwood 165 gr hollow points. They came in at ~1340 fps at 5 yards. Fun day. I'm thinking about a holster and making this unit a cold weather carry piece.
