Rebarreling Steyr 1895 straight pull
Gents, I recently completed this conversion from the 8mm steyr to 7.62x54 R
Completely straight foreward. I used a new 03-a3 bbl from SARCO ($150)
and cut the chamber with a JGS 7.62 reamer with a modified leade and throat.
The stock 7.62 reamer has a 1/2 degree leade starting at the case mouth.
NO throat. I had jGS grind a groove dia throat, with a 1 1/2 degree leade
Easy rechamber.
Rifle feeds and shoots perfectly without pressure signs. Yes I know the bbl is .308
NOT .311. No matter, it shoots around 1 inch at 100 yds.
Recoil on the carbine is stout, so i fitted a muzzle brake for comfort.
This is an easy conversion.
Just FYI, I also had JGS do a reamer for me which I named .308x54R It is similar
to the other reamer but the throat and leade are for .308 dia NOT .311
If you are going to use a .308 bbl, and .308 bullets (because of selection)
this is the way to go.
Turns out , std 7.62x54R sizing dies reduce the neck below .308 diameter.
So, just use a standard .308 neck expander instead of .311, and there are
your 'wildcat' .308x54R reloading dies.
I use Norma, Lapua, and Winchester brass.
Remington 700 PSS bbls on Mosin Nagant M44 receivers will easily hold 3/8ths
to 1/2 at 100yds, with a 9 power scope, new main spring,
and lightened cocking piece.
The ATI stock provides good neutral bedding.
But I'm a military rifle weenie.......
A few other M-N projects....Reduced striker fall (speedlock) and Timney style
trigger. I have designed the trigger, and built a couple of prototypes.
Results are promising, with crisp pulls in the 1.5 to 4.5 pound area.
Still trying solve the ' thumb-safety/bolt-release-in-one-lever issue.'
Regards to all

For those that have converted to 7.62x54, is the increase in operating pressure a worry? I can find no evidence of a M95 blowing up, but I am aware that the 8x56R lives at pressures much less than the russian cartridge. If one were to exclusively reload for this converted rifle, that'd be fine, but what about when your decendents inherit the rifle, they pick up some surplus ammo to run through it.... recipe for disaster?
for the 30-40 crowd, has anyone used a take-off barrel from a Rem 700 or a Win 70? I know the 03-A3 has enough meat, but they're kinda hard to find, and the Enfield 14/17 also have enough meat. but would a barrel blank be a better choice, shank size wise? i don't want to get the barrel too thin over the throat of the cartridge.
is either of these rounds a better match for the M95? i've tried a dummy 30-40 in the bolt, and it seems fit ok, not too sloppy. is the 7.62 tight at all? i know the rim diameter is a bit larger...
Thanks for any help you can provide. I've played around a lot with mausers and standard cartridges ('06, 6mm, .35 whelen, etc.) but am excited about this little rifle!
