Re: Misfires

Do you mean the C shape? That's just the branding. I will try that with the bolt, it has sat clocked in the safe for a long time.[/quote]

Therein lies your problem!! New spring will fix it.

Re: Misfires

Omarks suffer from weak ignition at the best of times. Have your firing pin protrusion checked, replace the spring and if you have an adaptor and aftermarket trigger fitted have the firing pin fall checked. Make sure your primer pockets are cleaned and the primers seated against the bottom of the po...

Re: 6.6-284

Hi all, Interested in 6.5-284 , what would be good powder for heavy pills and 30” plus barrels , keeping in mind better throat/barrel life , would 2217 , reloaded 26 be an option ? Any knowledge appreciated Cheers I don't think it will matter much, barrel life in any caliber with high bore gas volu...

Re: Proj jump - barrel wear

This is a debatable point, any difference in throat erosion rates between jam and jump cannot be measured and will forever be open to debate. Any difference would be so slight and would be lost in all the other factors pertaining to barrel life in general. My observation is that no two barrels of th...

Re: Concentricity

Well you were spot on Graham, I didn't realise how much difference there was in Berger 155.5's. I purchased a Shars comparator from BRT to check the base to ogive. There was 5 thou difference in a 100 pack of projectiles (I measured 2 x 100 packs). First pack had 51 of the same measurement, 34 with...

Re: Ogive to base measurement.

I have no information on tolerances and whether it is worth going to the extra trouble and measuring bearing surface. Could be - maybe ? Most comparators measuring base-ogive use a dial gauge directly on the base. If a small 'tube' was made to fit on the dial gauge stem or thread into the dial gaug...

Re: Sweet's Oil

Keith, You don't know 'till you've tried it! Some have ingredients hot enough to strip a sewerage pipe. That said, no way would I put Sweet's Oil on anything I intended to smell, let alone eat. You do mean Sweet's solvent re the smell don't you John? Sweet's oil has a quite neutral smell, I believe...

Re: Sweet's Oil

I noticed on the bottle it says SHAKE WELL, and not having done that very often, I'm wondering if I'm getting a solution that is depleted in some way. It's thixotropic and you shake it to make it runny. After sitting for a while it goes back to its normal viscosity. Just like tomato sauce :D . I wo...

Re: Sweet's Oil

Sounds like a mine field Keith. So when barrel "x" won't shoot and everything else is all top notch ( lets say it's a serious F Open rifle ) does the gunsmith straight away measure the bore ? And if they do how often is a problem found ?[/quote] Samples of the bullet to be used should be m...

Re: Sweet's Oil

...Alan, it is my firm belief that a barrel that takes an inordinate number of shots to "settle" after cleaning is not clean at all... Keith, this is just a theory, but if you have a bullet that is a tad too small for the bore (or a bore that's a tad too big for the bullet), then maybe it...

Re: 308/260 Rem FLS dies

I use a Wilson bushing type FLS die on my .308s. Given that all the dimensions except for the neck dia and shoulder length are the same, can I use the 308 die with an appropriate bushing to resize 260 Rem cases? Pete Yes, but you may find after a couple of resizings that a small ring will form arou...

Re: Sweet's Oil

Just out of curiosity - is there a reason to shoot the first bullet in a match with oil in the barrel...if so does that apply when doing load dev? I'm curious - I don't shoot with oil in the bore so maybe there is something to learn here (not sure I'm gonna change what has been working but interest...

Re: Sweet's Oil

Years of observation and experience tells me that the first shot through a squeaky clean barrel will "lay" down as much copper fouling as the next five shots... Another question Keith, in your experience why do some barrels do a high first shot. I often see this for the second and subsequ...
