After all the recent threads on HMR ammo issues and viewing the previous threads there is obviously a common fault with the ammo being inconsistent. What are people's thoughts/opinions/knowledge on why the inconsistencies exist and why some people/rifles just can't get on with them.
A few I can think of are,
All ammo (apart from Winchester) is made in the same place so if one brand isn't very good then by some logic all will be the same
The ammo is loaded to the same specs so if your rifle doesn't like that spec it won't produce the best groups
The split necks lead to different neck tension and therefore different pressures and velocity and so larger group sizes
The split necks may cause powder to be contaminated by moisture and therefore different burn rates
These are just my thoughts on the matter and I may be wildly off on these theories so I'd like to hear what others think. This then leads on to changing my HMR for a WMR as by my logic it would remove the split neck issue (and problems associated) and also there is a much wider choice of bullet type and weight so with trial and error I should be able to find a combo that works well in whatever WMR rifle I chose. Thoughts?
