I have been kicking around the idea of converting my 116 weather warrior 7mm rem mag into a 7.21 Lazzoroni Firebird.
I hope to gain some information from those of you with more experience building Savages then I have.
The biggest question I have right now is about bolt head. From what reading I have done this far I "think" I should be bale to use the bolt head from a 300 wsm as there is very little difference in case base diameter (.555 vs .583). Does anyone have any experience with this?
I am pretty sure the 7.21 will fit the magazine from the 7mm rem mag but before I move forward I plan in seating a bullet out further in a 7mm rem mag case to mimic the length of a 7.21 firebird.
If all goes well I hope to order a barrel and start this build in the near future.
Thank you for any help you have to offer.
Cheers
Sean
