    Whoop! Whoop! Thread resurrection alert!

     

    Why might one need a 'grab bag'? Does this have anything to do with zombies?

    It could be zombies, plagues of locusts, nuclear holocaust, the Greens winning the election - anything that might require a prepared daysack or bergen that is always good to go. It would be the one thing you would want/need to grab in a sheet hits the fan scenario, which would allow you sufficient supplies and equipment to make a fist of immediate survival.

  2. As Andrew says really. What is your aim - cheap and plentiful plinking ammo, robust hunting round, decent target round or platinum laser? It's easy enough to look at a few components (powder, round, brass) and then work out a rough costing. Powder is easy enough to estimate - get an average per round grain weight and divide a pot of powder by that grain weight to figure out roughly how many rounds you'll get.

    Seems so the last owner/investor group must have had the collective head stuffed in the dark and smelly area. Maybe this time they just make a quality product and stop bleeding money.

    Agreed - make good equipment and leave the crappy rubber stocks  and gewgaws off those firearms! Narrow the product line down again and pay attention to fit and finish of the product that hits the shelves.

    I would think you'd get the most un-uniform barrel conditions, shot to shot, for the first few shots. Unless you clean and allow to cool between each shot.

    True the starting conditions should be the same but the first shot will lay some residue down the barrel, the next will remove some and lay some more, and so on. It'll take a few shots before the last bullet fired removes the same amount of residue as it leaves behind giving you the most uniform conditions, shot to shot.It may be predictable but it does alter the POA/POI.

    It's what fouling shots are for.

     

    I agree with that in a targetry context. I should have clarified that this, for me, is mostly in a hunting context, where the first shot should be the only shot (unless there is a second animal to shoot later). So when I zero at 100m, I would want my cold bore shot to be the same as my first shot in the field.

    So you meant, over oiling may cause damage - yes fully agree for the reasons you stated.  A light patched-out oil residue is neither here nor there in my experience and it's standard practice (when I was a lad) in the forces.

    Sure, and probably ok with a very lightly oiled barrel. I have decided to keep it as uniform and routine as possible, so patch out with alcohol, then dry before shooting. That way I know it is clear, and will minimise as much variation as possible (maybe one instance there was more oil than usual, maybe one time it evaporated more than others, maybe a piece of grit gets stuck in some tacky oil etc etc).

     Cold bore shots imho have a different POI due to powder or copper residues affecting barrel pressures on subsequent shots.  That and perhaps a warming barrel/chamber.  I can't see any other reason why a cold bore shot would differ (but they do!).  

    If the warming of the chamber and barrel was a factor, would a string of shots therefore not all result in different POI's? Until you reach a critical temperature and it stabilises?

    "Damage of oil"  ?  Please explain.

    Cleaning out with meths (denatured ethanol) is not necessary or desirable as ethanol is hygroscopic so any absorbed water may remain in the bore.

    Oil does not compress well, so oil in the bore is not a great idea with a high speed high pressure round screaming down the barrel. In extreme cases (a greater amount of oil) a bulge or pressure ring could be created. Plus, oil in a barrel creates a nasty signature puff of smoke (at least with the first round). To wit, I do leave my carbon steel barrel with a light coating of Ballistol, but prior to shooting it is given a patch with a meths patch followed by a dry patch or two. I don't run it through with a meths or alcohol patch and then leave it for days, usually as close to shooting as possible.

  8. A theory I subscribe to is one aired by Ryan Cleckner (shooting instructor). He thinks that it can be directly attributed to the shooter not being warmed up, rather than the condition of the barrel. He recommends 'warming up' by properly testing and adjusting position, dry firing and calling your shots (gauging your dry fire let offs). This makes a lot of sense to me - it's common to see people go straight from waiting around to straight on the rifle and firing. You wouldn't do this if you were golfing, as an example, would you? No, you would at least take some warm up swings rather than the first swing being the warm up (and a rubbish hit).
