I have some spare money...

[Ragnarok]

So, I'm closing on the end of the Uni semester, surprisingly with a large amount of cash in my bank account.

As I never bought myself a proper present for my birthday last month, I thought I might treat myself a little with a little of the money - obviously nothing too much, but a couple of things won't hurt.

I sort of have a leaning towards a decent shooting chronograph and 2 d.p. top pan balance so I can work out my muzzle energies nicely.
I have a bodged home-made chrony that largely matches GGDT, but accurate numbers would be even better.

I was thinking either the F1 chrony or maybe the higher model, the Alpha. They're a little pricey, but they get consistently good reviews.
The F1 is the way I'm thinking right now, not sure an extra £42 for the pretty simple auto functions on the Alpha is worth it - 10 seconds and a calculator would do that fine.

I'm also planning on getting a cheapish compressor with a homemade after-booster to get the pressures needed for HEAL's upgrades, but that was planned anyway.

Has anyone got a different suggestion?
I'm not building a new launcher yet, I always design really heavily, and I haven't got a complete design that wows me enough right now.

You could opt for a large rod of tungsten! I'd go with the basic chrony and spend the rest on "other things"

[Ragnarok]

I can't get tungsten rod easily. But a tungsten APDSFS round would be the bomb if I could make one.

I have a nice heavy chunk of 20mm steel rod to make up for it instead that weighs about 300g, less if I were to sharpen it. Recoil will be insane if I ever fire it.

send it to me

no seriosuly, get an Alpha chrony. I have one on loan at the moment, expect some results soon

[Ragnarok]

Well, the Alpha's extra features, aside from the fact it will actually show in m/s, are only really useful if all my ammo weighs the same to within a few percent, which a lot of it won't.

Most of it is just standard spreadsheet or calculator stuff anyway, and that will account for the varying ammo weights as well.

I still want to see how much I'm scaring the sound barrier though...

Dammit I'm all out of 0.12 gram BBs, I really wanted to check how fast they went in my burst disk pneumatic. Fired a couple of shots from my 3/4" pneumatic, I got 210 feet per second for a 28 gram slug at 100 psi, fairly respectable.

My second chronograph (Oehler Model 35P) has separate,replaceable sky screens (sensors) and main unit.
If I knew what was going to happen,,, I would have at least made a "bulletproof shield for the first one.

for what its worth
