Along the way he has responded to a Remington factory re-call notice that required the fitting of a replacement trigger assembly to the 700s action for safety reasons.
The sub-sonic loads for the Russian Saiga mean that he is permitted to use it on our pistol club range. - Our range site is certified for use with all New Zealand legal firearms - but out of consideration to neighbouring properties we have restricted to use of centre-fire rifles (supersonic) and shotguns.
'Cutters' Silenced Saiga 7.62x39mm Russian.
And 'Cutters' - like me - fully appreciates the use of a silenced firearm with its obvious benefit of causing much less disturbance to hunted game, pests and neighbours.
It needs to be said that there is no such thing as a silent firearm - all those movies showing a revolver fitted with a screw-on "silencer" that goes "phttt" when the trigger is squeezed are total works of fiction. - However a generously sized well-made sound-moderator can be very effective in taking the BANG out of bang when fitted to the most suited firearms action.
Revolvers are not suitable because of the leaky cylinder gap - and semi-autos have actions that cycle open before the gas pressure has dissipated allowing noise to escape (unless you lock the action shut).
For best effect with a conventional moderated firearm - select a manual or bolt-action.
- All that being said is as a general rule - However there is a system (Russian) that uses 'captive-piston cartridges' that is very close to silent for covert use.( See my post 10 July 2014).
Sub-Sonic 7.62x39mm:
- Cutters has worked-up a satisfactory load that works in his Saiga when fitted with his 'silencer'.
First drill-out the flash hole from the primer pockets to 9/64 of an inch (and de-burr) keeping these cases solely for sub-sonic loading. The cases are primed using Large Rifle Magnum primers. He is using cast-lead gas-checked flat-bottomed projectiles with a pointed nose weighing 186gn that he buys for 27cents NZ each. He applies a light taper crimp.
The bullets are seated in front of 11.5gns of AR2205 powder (as thrown) and this loading - in his gun - works well and cycles the action when the silencer is mounted. - It does not cycle the action if the silencer is removed.
- Warning: This is an example of a safely developed hand-load - do not copy it and presume that it will be safe in your rifle.

Here in New Zealand this load works-out cheaper than imported Chinese military surplus ammunition.

.300" Blackout Sub-Sonic:
'Cutters' .300 Blackout gun is a pre-owned Remington 700 'SPS Tactical' with 5R rifling in 1:7 twist suitable to stabilise heavier bullet weights.
'Cutters ' is developing loads using a range of projectiles for the 300 Blackout all intended to make sub-sonic velocities (as well as normal super-sonic loads). He has a selection of bullets weighing 120gn, 150gn, 166gn, 186gn, and 235gn .
Cutters comments that the limited case capacity of the 300 Blackout suggests that there likely would not be any issue with too much air-space behind the loaded pills - as the cases are roughly similar in size to a .357 Magnum pistol round - but may be fitted with larger/longer pills.

You'd best be warned that fitting "silencers" to guns is not always a simple job - Cutters has an issue with deflection (alignment) on one of his after-market fitted moderators - and I have a semi-auto .22" pistol that tends to destroy silencer baffles repeatedly (that's again & again & ..)!
Note: Rod (gundoc@xtra.co.nz) says that misalignment problems are readily corrected by a decent gunsmith - even my sloppy muzzle thread issue on my Browning Buckmark can be resolved.
- It all adds "spice" to life eh!
