I have been told to be carefull with my brake design as many people are concerned that it will be blatantly plagerised, like another popular kiwi made brake recently :wtfsmilie:[/QUOTE]


Mr Greg...

Firstly I haven't had alot of experience with the 180gr hybrid but was quoting you from another post saying you had shot alot of them and they only expanded okay up to 850 yards in your big 7mms? and...

The 195gr will be a hunting bullet so should have a hunting jacket? not like the 180gr target hybrid with a thick jacket that even you admit will only expand up to a modest distance.

The trouble with any extreme over bore case like the very big 7mms when you talk about barrel life isn't just that its short its that they are sometimes very hard to keep tuned with the best BC...

The big question of terminal performance and useful case size will be limited by the jacket thickness that berger ends up having to use to get them working well in a 1-8 twist only time will tell....

A 7mm rum should give you 3000-3100 depending on barrel length
The 7mm lapua imp 3200-3300 but dont expect the barrel to last to long.
