Nice discussion on rebated boat tail bullets.

 Sadly, no real conclusion but their videos is always interesting - especially the ELR stuff.

We use Lapua D46 and MME bullets, both of which have rebated boat tails, and find them to maintain accuracy and  grouping at longer ranges better than conventional bullets. The MME bullets are quite economical too !

In 308? Past 1,000 yards? I like the idea of supporting MME…

[meles meles]

In 6.5 (x55)mm, .308" and .338". The first two calibres to 1200 mards using MME Wimbledon Match and the last using Mistral-T out to 2,000 mards.

I’m impressed - what barrel length in the 308? 155, 168 or heavier.

Thanks, always good to learn something new.

To all accounts a good guy to deal with, and British.

The discussion did get me thinking- I have a Krieger  barrel on an AXMC (338 lm) that shoots Lapua, Berger and Hornady well. When we tried the same loads in my mates AXMC with a U.K. factory barrel only the Lapua performed as desired. He ordered a new factory AI barrel from the USA ( I believe they use Bartlein barrels) and it shoots as good as my Krieger. 

There are too many possibilities ( ogive shape, crowning, throating, chamber specs)but boat tail design maybe affected by all the above. 

I’ve haven’t  seen much love for the 250grn Scenar Lock-Base but it seems to me to be sort of following the idea of a rebated boat tail.

L to R ( lined up on boat tail line) 250g Scenar, 250g Lock Base, 250g Berger Hybrid , 285 ELD-M ( plastic tip missing ). Berger easily has the longest boat tail. Not much difference between the others.
