I am having a McGowan barrel made for this caliber. I am also ordering a reamer with a floating pilot from Pacific Tool and Gauge. My only question is, how long to throat the barrel. I will be shooting 139-142 grain Scenars,VLDS, and SMK's. Any suggestions on overall length?

Thanks for the reply Wade! How far into the lands are you seating in your ackly swede? And what is your COAL? If you don't mind sharing.

I have not had a chance to fire the improved swede yet I just got the barreled action back from my gunsmith and will be putting it into a new stock which is not done yet. On other 6.5's I usually put Berger VLDs 0.005-0.015" into the lands.

Do you think that using a standard chamber would inhibit my ability to use the long bullets. I.E. Losing powder capacity from having to seat them too deep?

Re: Throat length for my 6.5x55 Swede barrel
The original 6.5 x 55 was loaded with heavy long bullets and they always did fine even when loaded to lower pressures as was necessary given the age of some of guns chambered for this round on racks. Loading to modern pressures there is no problem getting enough powder capacity to effectively shoot the 140's.
I went with the AI as it gives me a little more capacity for more muzzle velocity as this is on my F-class rig.

Seems you'd make dummy rounds with different bullets seated to allow moving .rearward for setback and forward for n future throat erosion. Then you'd measure ogive to base and compare to the reamer? I was "told" Pacific AI reamer has 0 freebore by Jay at Pacnor
So a throating reamer for the difference?
Magazine length is relative...
Haven't calculated mine as yet as I can't find bullets..
