You did not say what year your Husqvarna m/38 has engraved on the front receiver ring.
Husqvarna was contracted to make 23.5 inch barreled m/38 rifles starting in 1941 when the conversion of m/96 rifles could not keep up with WWII swirling all around Sweden.
They made:
28,672 in 1941
38,781 in 1942
14,156 in 1943
1,969 in 1944.
They also made a few m/96 (29 inch barrel) long rifles for the FSR during WWII.
These are rather sought after.
1943=@8,750 Husqvarna m/96 rifles
1944=@ 5,328 Husqvarna m/96 rifles
Your m/38 rifle has a rifling twist of one turn in 200mm or about a 1 in 7.5in twist.
Your bolt may have been replaced at some time. Husqvarna parts are stamped with a tilted crown. Carl Gustaf parts have an upright crown and the old Oberndorf Mauser factory parts have a crown with a baggy looking bottom.
Husqvarna also made replacement parts for many years. And they also made the upgrade parts for all the rifles and carbines on a contract basis.
So they made both straight and bent bolts.
Many rifles were still being armory re-built and stored up into the 1970s. At that time they used whatever new parts they still had on hand.
You will find that US and Korean(PMC) ammo has undersized brass. It is ok for a couple reloads and then it has problems. PMC is the worst as far as size is concerned.
The BEST brass for hand-loading the 6.5x55 Swede is Lapua. I have some that has been reloaded 14 times.
In fact I just won a match using that old Lapua brass, using my 1943 Husqvarna m/38. And fairly hot loads.
