Update on this thread for the amazing authors
@Dirtdart @HWL @Brian Rothhammer
I have a 6.5MS retailed and regulated by Westley Richards, 1903 type. I understand feed and land depth are tricky on this rifle from all I’ve read.
I tried to look around for good round nose options beyond the Hornady that appears cannot be crimped to the ferrule since its so far forward on the bullet. Norma makes a 156gr Vulcan that has a cannalure very low on the round. Has anyone tried this one as a hunting bullet?
Any other options that feed from the magazine on the British tuned and retailed 1903s you might suggest?
Wow.. I've been upgraded to "amazing author" (along with HWL and Dirtdart)!
I do not own an M1903 but do own and load for a M1910 (9.5X57) and can tell you that proper bullet profile and cartridge overall length are vital to the smooth operation of a pre M1924 Schoenauer magazine.
The matter is discussed in some detail on this thread starting with the third post down:
https://www.africahunting.com/threa...908-m1910-m1924-m1925-or-high-velocity.47277/ .
The essential part is that you must have enough 'meat' at the critical area (on 9.5X57 it's the 'top' third of the projectile) to engage the guides machined into Otto Schoenauer's marvelous rotary magazine.
Once you have cartridges of the proper profile, as fellow 'amazing author' Dirtdart posted; "The beauty of my little MS 6.5x 54 is that when you get the right combination the rounds feed as smooth as any bolt gun I have ever seen."
Build your 6.5X54 like this and they should feed smoother than a hot knife on ice:
I would suggest building at least five rounds (live or 'dummy') to the
precise dimensions of the Eley drawing above, even if it involves cannibalizing projectiles from vintage cartridges such as DWM 477. With five rounds of the correct dimensions to feed to her, you'll know if your MS is properly configured for its original ammo and should see how delightfully smooth a Mannlicher Schoenauer action and magazine are. It should function flawlessly and consistently so.
That will give you a baseline from which to model additional cartridges.
To again quote Dirtdart; "I am not going to waste time working on a load for accuracy or chronograph anything that does not function to complete satisfaction first. If it don't feed they ain't no need."
Cartridges with other bullet profiles, however, may still be used to 'top off' the Schoenauer magazine.
If you have cartridges that shoot wonderfully but don't feed well, either load only two
or load three proper fitting cartridges first and then two of the problematic ones. By doing such one can use the ill fitting rounds with the magazine operating smoothly.
