With my home drilled weaver rail now being ok, ive loctited it on the rifle.
Next outing will be zeroing and load development.

Thanks to all your help on this thread Dave (warbucks)

Sounds like good results but a contrary voice if I may?

I would use a faster burning powder.

I use 45.5 grains of H4895 under a 55 grain BT in my 243 and get 4025 fps.

I also use a ASE SL5i moderator and can see the muzzle flash under NV.

With 48 grains of a slower powder, resulting in a MV of 3500, I am guessing the load is lower pressure and there will be more unburnt powder coming out of the muzzle than with my load.

Are you seeing this flash with your mod and under your NV?
