Does this hold true from 30” down to sub 20”?
That Im not entirely sure of? I know down to 22" from 26" its true and Im not sure you gain at the same rate above 26" either? In general though, its little loss in most normal barrel lengths.

Rich,

you might be able to get a good idea by using quickload reducing the barrel length on a known load and look at the powder burn %. Tweak the heat energy of the powder to correct the vel to match real world.

At some point there will be a jump. Depending on the specific powder burn rate will effect that exact point. Its rarely linear. Between certain lengths it maybe single digits and others jump to 20.

A long burnout barrel and a cutoff saw is the sure way. Issue is with the 338 bore that could be 4k+ rds.

Oh yea, just wait patiently to finish shooting out my win mag barrel. You, rich, are an evil genius, so says my wallet and my wife. Couldn't ask for a better set up for ease of change. I am super tempted to take my wife's 30-06 and set to a 300 sherman but then she wouldn't have to lead me so much to shoot me with it.

Does anyone know if this can be done (barrel set back and reamed out) with a Tikka T3/T3X? They seem short shanked to start with... Donor chamber/barrel would be a 338 win mag. Or is a new barrel going to be required?

Thanks.



Edit post to clarify question.

I will let rich confirm but I am 99% sure it can be because the 7 sherman max will work on a tika t3 so I dont know why the 338 max wouldn't work .

There have been several built. The difference here would be cutting off some shank and rechambering the same barrel. The WM chamber is about 1/2" longer but I dont see where that would be a problem. If you were cutting forward of the old chamber, it could be a problem at some point with strength. Maybe a smith could chime in, but thats how I see it.

Whidden dies and 338 max headstamp brass available now? Do you still need to neck up the brass?

Considering a build on a LA Borden that I just got.
