Thread: Subsonic load for 308

I’ve seen people drill out the flash hole to guarantee a god burn rate when using trail boss? Is this necessary or just a waste of time?

I was told I didn't need to, so I don't.

I skimmed through the Hodgdon sheet on using Trail Boss for reduced loads in rifles and a later article on the same subject by John Haviland on loaddata.com. Neither mentioned drilling out flash holes so I will not do it. Incidentally John got about 1050 feet per second from both 150 and 165 grain jacketed projectiles in a 16 inch barrel.

Any body recommending drilling out flash holes steer clear of him he is an idiot, And knows little about reloading and nothing about cast bullets and loading subsonic loads.
I have a note on my pad to message you, I am back casting again, what was it you need I will fit it in some where I have couple of big orders to do but it is good to take a break
and cast something else.
