New to the Forum, great place to be with some superb forums, pleased to be part of it.
There are so many myths and opinions on .308 Subsonic reloading (or subsonic centrefire generally).
I would greatly appreciate some input from the forum from people who have a lot more experience in these matters than I do.
I plan to use Lapua Brass with Lapua Subsonic 308 200GRN FMJBT.
So a few questions if I may:
1) POWDER
The first issue I have here in Europe is that I cannot buy Trailboss which is clearly the favourite for subsonic reloading due to burn rate and density.
I can however purchase VihtaVouri N32C (Tin Star), N310 or RedDot. I am favouring Tin Star as it appears the most dense by far if not equal to Trailboss a good second.
Thoughts on these powders much appreciated.
Load wise I appreciate to start high and work down with no Moderator on and try and achieve around 950-980 FPS presuming the Moderator may add around 50FPS when fitted.
2) PRIMER & PRIMER HOLE
There is so much differing opinion here. Ranging from drilling out the primer holes and using Magnum primers to not drilling out and using small rifle primers.
The concern here being powder lying in the case and not being detonated quickly/equally and the issues that will bring, is this still the case with a dense powder like Tin Star.
So what is the answer, drill or not drill, magnum primers or small rifle?
3) BULLET LUBRICATION
Some say lube and some say not needed especially with copper jackets. Some say even with copper go with Moly. I am not sure where to start here.
I would say that, at great expense, I purchased some RUAG factory .308 subsonic (apparently used by police and military in Europe) which has a 200 grain FMJ with a ring of lube around the ogive, see picture below. This ammunition is clearly of the highest quality and they are lubricating the bullets, see picture below.
I know there is a wealth of knowledge within the Forum and it would be great to put these myths to bed once and for all.
Thank you All.
