Re: Alpha munitions brass

I have been revisiting the old 6.5x55. It would be perhaps 18 years ago that I started shooting a slightly modified 6.5x55 Swedish as an FO cartridge and it won quite a few shoots back then. Just why I am experimenting again with it is a long story but a few things I have observed may be of interest...

Re: Barnard V block dimensions

Batattack wrote What's your thoughts on heavily relieving (1-2mm) the central section effectively leaving two V topped pillars 25mm long they are still connected by the lower section of the block? If you like. But make sure the hold down screws come through the middle of each 'V shaped Pillar'. When...

Re: Barnard V block dimensions

I have made some a little longer. Depends a bit on your stock design of course. Not hard to make if you need one in a hurry. If you make an equivalent it is important that longitudinally it is never convex - even a tiny bit. Preferably very slight concave of a few thou or else relieved a few thou do...

Re: Victorian Queens Series - 2018

I have started another Topic on which eTargets are goodenough for major events. This is a serious study after years of collecting data and analysis of the impact of less than perfect Targets on the results of a major shoot. I believe it compliments many comments and questions brought up in this topi...

Re: Lee Collet Neck Die

I agree with John and Keith. They work. A little bit of polishing the collet closer mechanism makes them work better and is quick and easy to do. Lee make some crap stuff and some quite good stuff. The trick is to understand and separate them. I think a lot of people miss the point that Lee Collet D...

Re: Volume sorting cases?

By Shoot them once carefully. Preferably all with the same load. I mean it is wise to use only moderate loads first shot. And all fired the same number of times. Preferably with zero headspace or loaded a little into the lands such that the projectile pushes the case fully back onto the boltface. Di...

Re: NECK SIZING

It is very difficult giving advice without being able to see details. Easy to go off on a tangent or miss things. I never considered that case head separation was part of this discussion because the brass is almost new and heavy loads were suggested by some past ladder testing. Good brass will take ...

Re: Volume sorting cases?

I do like JKs last good reason to volume sort using a fine ball powder Namely Volumetric changes are less discernible so you'll worry less Seriously I feel that weight sorting is worthwhile for extreme range shooting at the top level of competition. Volume sorting sounds great until you try it in th...

Re: NECK SIZING

One possible factor that can make nice fitting cases vary in feel when feeding them loaded into a rifle is the depth of a primer insertion. If you are running very neat fitting cases, just a minute difference in primer insertion can make a big difference to feel when shooting. This can be checked by...

Re: Hexagonal Boron Nitride

Pool shops often keep a range of chemicals including Iso Propyl Alcohol in large quantities which is fairly pure. A good general cleaning solvent including lenses and fairly innocuous stuff.

BTW, I will persist in writing it my way despite the IUPAC straight jacketed terminology.

Re: BURRIS XTR-II F CLASS SCOPE 8-40 FFP with MOA reticle

First thing - what will be the intended use of the scope ? FO, FS or FTR. Or other shooting disciplines. Scope weight becomes a factor to consider. 40 minutes elevation is OK with care but it depends a lot on the cartridge and distances you intend to shoot. You seem to be placing a lot of weight on ...

Re: BURRIS XTR-II F CLASS SCOPE 8-40 FFP with MOA reticle

I personally would not recommend a riflescope for F shooting of less than 40 magnification. Most F class shooters that I know of benefit from more than that. A NF BR of 10-42 can always be set down to 32 or 25 if you wish. For hunting or some other type of shooting less may make more sense. Another ...

Accuracy of large PAPER targets

Of basic importance to the choice of using eTargets for top level competitive shooting at long range, is, just how accurate are our present paper targets. Previously, some guesses have been made. Now the result of a study of the accuracy of six 800y - 1000y target faces comprising measurements at 96...

Re: Somchem S365 South Africa , Next World Champs

Rules I think limit caliber to 8mm.

So it is obviously going to be a 338-8mm. Or 338-308 !!!!

Just play around and make no commitment for a while yet. Accuracy and shootability are still paramount and I expect the 7 SAUM still will be a good contender.
