Reloading .303 - Indoor Range Limit

[FredB]

I will repeat what I posted above. The .22 long rifle was not originally designed as a pistol cartridge. In the 19th century, the standard revolver .22 cartridge was the .22 short. The NRA has already dot rid of the stupid "pistol calibre" restrictions (which stopped me using a 44-40 in comps at one time) and replaced it with the standard gallery range limitation.

The standard referance I use 3392.... http://www.full-bore.co.uk/viewtopic.php?f=36&t=810
I've safely loaded thousands of rounds based on this info.
Enjoy your loading and shooting.

Excellent info Joe, many thanks. It seems as if Mr Harris is a well regarded and reliable source. I'm sure a few more questions will pop up but this is a great start.

Also check if your range has a limit on Foot Pounds Energy (FPE) as well 1750 FPS, these are two different and confusing limits. What might be under your FPS could be over your FPE. Also our range has been caught out on the HV 'downloaded' centre fire ammunition, as the certificate has been issued by the NSRA (utter fools in my opinion) which we are trying to sort out now.

Very good point hobbesy. As I recall the range cert states a velocity limit of 1750 fps and an energy limit of 450 ft/lbs. Clearly 1750 fps for say, a 150-grain bullet takes it well over twice over the range energy limit at 1020 ft/lbs. Therefore using the opposite formula, I would need to look at just over 1162 fps as the maximum velocity of the same bullet at 450 ft/lbs.

As you say very confusing if you take each limit in isolation but I think it's pretty clear, once it's pointed out of course. I'm fairly certain the cert has been issued by the NSRA as well.
Thanks, David

Would chamber inserts have to be proof tested to be sold in the uk legally ??

They are pressure bearing so I would say yes they need to be in Proof and the good news is chamber inserts from someone like LW would be proofed.

I know C&G want you to have a variation for them

Strange....given they're not a barrel but could technically be viewed as Section 5 by some as they don't meet minimum length rules. ..though I can also see why SOME would want them proofed due to pressure bearing reasons....but you could equally argue that they're a cartridge "case"

They look like a cartridge case, so.....? ? ?

As far as I know they're not. They are non rifled chambers held within the proofed chamber, they are not really chambers in their own right! Because they're not rifled, no variation required, afaik.

I think I will just carry on using the original cases with cast bullets and fast pistol powders a lot less faff on.
