Meplat Trimming????

[Flex686]

What's the best way to do meplat trimming? What are the advantages to it? I just heard of it, and was wondering if it's something I should look into

I have been doing this. Got the 6mm and 7mm setup from Sinclair's for the berger vld's. I am told it improves consistency but you loose a little of the BC. I am not using it like I thought I would.
Complete new set up available if you are interested.

I only trim meplats on 300 SMKs. I use a small hobby lathe set up for that purpose.

I have not done it myself...but with quality bullets now days, you most likely do not have to worry too much.

I have found that bergers are the best and hornady...well they are not as good but still shoot lights out.

The Hoover pointing die is excellent, and you get punches matching spesific bullets, itis also not made of plastic.

As for trimmer the fastet and most convenient i Tried,is using the meplat kit for the Giraud trimmers.
Accuracy is on par with the Hoover, i do use both as it's sometimes faster not to change heads on the Giraud, and just chuck the Hoover with the drill.
Will be better when i get another trimmer for the task.

So far Only trimmed 7mm bullets though but it works well.
Just dont overdo any of them.

FROM WHAT I HAVE READ...only. I have never done it myself. But I traded some bullets for some that were done, (my benchrest bullets done by a friend. Trimmed only.). 100, 200 & 300 yard benchrest, I couldn't measure any difference after 5, 5 shot groups at all three distances. Shot with my regular bench gun setup.

I started this whole thing with trimming meplats years ago. Each bullet is unique and has different flight properties which show up in variations in BC. In bullets used for longer distances you don't see any gain from having trimmed meplats and thus uniform BC's until you get past 600yds. But after that it shows up on the target. Trimming reduces the BC an average of 2-3%, Tipping adds back 2-4%. It has become apparent that bullets manufactured with a secondary tip don't require the meplat to be trimmed. The secondary tip reduces the effect of a raggedy meplat to the point that you can't shoot the difference. With that said if your doing this yourself trim then point for concentricity and consistency.
