Any one shoot a rifle with a very long throat?
With long VLD type bullets seated into a cartridge with a standard chamber, the bullet must be seated well down into the case and this uses up powder capacity.
If you single load and don't use the magazine, then it would be possible to seat some of the VLD type bullets out quite a distance if the chamber is cut with a long throat.
This should be similar to having an improved chamber.
My lattest rifle is chambered this way and I seem to be getting about a 80 fps to 100 fps gain befor I see pressure signs.
I would be interested to hear from those that have tried this as to what sort of velocity gains they are getting over a standard chamber.
