Peregrine hunting bullets are manufactured with multiple seating rings (Please note that the VLR and VRG bullet families are not jump sensitive). These rings can be quite easily used as a reference for seating. For VLR4 and VLR5 Plainsmaster bullets there is normally only a single crimping ring. This crimping ring is usually related to SAAMI specifications to accommodate crimping for factory produced ammunition. As a rule of thumb we do not recommend crimping for bolt action rifles if smaller than 338 calibre. In most cases for VLR type bullets we recommend bullet seating such that the case mouth is in the middle of the first ring. See first three items in the illustration. For VRG2 and VRG3 Bushmaster bullets there may be one or two crimping rings. Any one of the two can be used. See the item far right in the illustration.
It is important to use the same seating arrangement when switching between expanding and non expanding bullets of the same family e.g. VLR4 and VLR5 or VRG2 and VRG3. The graphic illustration is just a recommendation as the re-loader may want to adapt the seating depth to personal preference for various reasons. Also note that reload data on our website suggest seating depths for each load that may be slightly different than the general guideline above.
In general it is advisable that 375 and bigger calibre’s require crimping to prevent the bullet from being knocked deeper into the case due to recoil. It is also recommended to perform a neck crimp regardless of the calibre size if the ammo will be fired from semi automatic or fully automatic rifles. A crimping groove can be identified by one face that is perpedicular to the case mouth. The rest of the grooves are slanted to allow smooth entry into the case neck.
Note: 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. To obtain a smaller final neck size / case mouth (also for thin walled cases) it may be a good idea to remove the decapping pin and then repeat the resizing procedure
