How To Correctly Seat Peregrine Bullets

Seating the depth of hunting bullets can be very simple. Here is how to do it.

Peregrine hunting bullets are manufactured with multiple seating rings. These rings can be quite easily used as a reference for seating. In most cases we recommend bullet seating such that only three quarters of the first ring be visible outside the case neck.
This will work for most hunting rifles and most of our recommended propellant charges.

The picture below shows from left to right the Peregrine Solid Copper range (VRG2), Peregrine BushMaster (VRG3), Peregrine PlainsMaster (VRG4) and Peregrine Match (VRG5). All four bullets in the image are 180grain 30 Cal.

This will also work to duplicate preferred loads when switching between bullet families by keeping the same weight for the Peregrine Match, the Peregrine PlainsMaster and the Peregrine BushMaster series. When loaded with three quarters of the first ring visible outside the case neck, bullets of all three families will shoot similar muzzle velocities to the same point of impact. To be more precise they will group similarly up to 200 yards. For a 300 yards zero the hunter may have to make small adjustments.

The graphic illustration is just a recommendation for the maximum seating depth as the reloader may want to reduce the seating depth for various reasons, such as increased powder capacity and reduced jump.

Full sizing / neck sizing may be slightly different with monolithic bullets than with lead-core bullets. The bullets may sit loosely in the case when following normal case resizing procedures or neck sizing. This is not due to our bullets being under size, but because the bullet has less bearing surface in contact with the case neck. To obtain a tighter final neck size / case mouth (also for thin walled cases) it may be a good idea to remove the case mouth expander / decapping pin and repeat the resizing procedure. This technique increases neck tension, which keeps our Peregrine monolithic bullets firmly seated.

For bigger calibers crimping can be done just after the first ring.

Please note: Reloading is dangerous and for the skilled person only. Always follow safe reloading practices. Peregrine Bullets may not be held responsible for any reloading suggestions. It is up the reloader to ensure good practice and personal safety while reloading.
