Rather difficult to fire a 550mm torpedo from the shoulder or hip but a few of us sub boys did shoot a 20mm sniping rifle from lower north gun battery in early 86

Quote from: Ds J on May 20, 2022, 10:55 PMWhat is an easy way to measure the bore of the rifle - slugging a 9mm LRN through it?

*******************
I have used cast bullets to slug a bore, usually a bit smaller caliber which I tap from top/front with a hammer to fatten them till they tight fit. If you can find old lead pipe from plumbing it is the best, pure lead in its softest form. If you get a piece, you can reuse it over and over to cast a plug, to make plug smaller roll between to boards, to make it fatter tap the end to squish it out.
Edit: Also, the fishing shops sell ball sinkers, the usually easy to use for this purpose and are surprisingly soft lead some times.

I think StaBALL is likely going to be the RSA propellant of choice, lot of talk - hype about it replacing many powders as the go too. Seems to be a very suitable propellant.

I am still following up, but I believe a large batch of S335 has just been released again. There was talk of problems in the transport sector of the operation, and when discussed, it came up that propellants needed transport and someone had not done their work properly.

Thanks, will see what's available.

I do not own a 6.5 Creedmoor goes against most manly rules etc. Nonetheless, the Lyman 49th edition lists IMR3031, IMR4895, 4064,4320 AND 4350.
Also Hodgdon 380 and 414.
Stabal 6.5 is touted as the answer in Port Elizabeth at present, but I have never seen a tin.
From what I have read Varget would likely be a good choice for your lighter bullets, I use it in the 7mm-08 for my son.
Limited knowledge regarding 6.5 Creedmoor I have.
 

Winchester StaBALL 6.5 seems to be the go at the moment (if you can get it)

From the shoulder or from a control point  I think I know where you going, you mos a Simonstown chappie ey? Rings a "Bell"

Staball 6.5 .

My son is using it for his competition rifles, 260 Rem, 6BR.

500 Jeffery.
