Need someone's help to chrono my RPG-7?

[agb104983]

Long story short, I have an NFA registered RPG-7. I have a military subcaliber training adapter that shoots a 7.62x39mm. The velocity of the round when it is fired is less than when it is fired out of a normal rifle because the training adapter has extremely deep rifling that allows gas to bleed off past the round to decrease velocity. Therefore, I need a chronograph to measure the approximate velocity. So I was hoping someone on here had a chronograph and land to use it. Obviously anyone that was willing to help would be able to shoot it themselves if they wanted to try it out.

I live in Midtown Tulsa but work in Collinsville so ideally someone in the Collinsville, Owasso, Claremore, Skiatook, or surrounding areas would be best. Here are some pictures since I know that's one of the first questions people here will ask.

If only someone would roll up into Tulsa Firearms with that thing.....

The thread title alone is pure gold.

I thought about bringing it by 2A to shoot one of these days but I haven't done so yet.

I dunno what Eric would say, but there's some insanely tight sphincters over at Tulsa Firearms.

Yeah I haven't felt the need to yet. I don't shoot it to incredibly often and I usually have access to land for shooting on a regular basis. Even though the adapter is basically a single shot rifle, I would imagine they might have some issues

Definitely a no-go at the range with that shoulder thing that goes up.

No kidding! When I first saw the title, I thought, "Is he talking about a rocket-propelled grenade???"

In case no one had seen the 7.62x39 adapter before, skip to 10:21:- https://youtu.be/8MrwJM1_kw8
