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.

Re: F-Open Calibre Poll - Long Range

I will add that I always shoot free recoil. And that includes the 7 SAUM. I point this out because I don't want people to discount the possibility of free recoil with big cartridges. And I am now forced to shoot what I call the crossover position (no jokes please !) That is from the left shoulder, l...

Re: Mastering velocity ES 284W

Maybe I did not explain my theory very well. I believe with extremely tight or zero tolerances on neck clearance and freebore diameter, jamming the projectile actually works against you with respect to best Vsd. If there is even a minute amount of cartridge runout, the jam will jack the projectile a...

Re: Mastering velocity ES 284W

I have given a lot of thought to the relative importance of neck clearance and adequate freebore diameter in really long range shooting compared to obsessive turned necks and snug fits in short range benchrest shooting. Short range shooting can tolerate far more variation in velocity and more of a l...

Re: F-Open Calibre Poll - Long Range

I think the transition point to a special rifle for the longs should be based on a distance further than 600y. 700y and 800y (an easy target anyway) can be shot well with a 'shorter range rifle' thus saving the special long range rifle barrel wear and tear. If 'long range' includes 1000y yards (many...
