M4-style (narrow) feed ramps may need to be polished/widened for optimized feeding of the Selous bullet – Here is a video on how to do that." and since they cost near what the lehigh does and more than the Makers I decided not to try them. The reason I didn't try the Discreet ballistics 188gr Selous Machined Expander Projectiles is the tips look like they could have some problems feeding and even on their site they say "Note: The Selous projectile feeds best with 300BLK specific feed ramps. There is one I haven't tried and is mentioned above. That alone cost me over $100 in just bullets shooting at paper. To give an example once I decided on the Lehigh as my subsonic home defense round I shot 84 rounds of the 194gr maximum expansions just to make sure they would reliably run in my gun under different situations and conditions. I am just a long time 300BLK enthusiast trying to share what it has taken me many hundreds of dollars in bullets to find out which one works the best. I am not associated with, paid by or have any contact with any bullet manufacture. The Makers worked very well and if you want to save a little money over the lehigh these are the ones to get. They even have a plunger in their bullet to ensure expansion once it hits any soft material or liquid. Lehigh also took a lot of time to designing it to feed reliably in any AR. Out of the two the 194gr Lehigh was the clear choice as they engineered the bullet to fully expand at very low velocities once it hits flesh. įor the makers I haven't tried them all and can only vouch for the 190gr, 200gr and 220gr expanding subsonics which I settled on the 200gr ones but all three did very well.Īll the other bullets could not be counted on to reliably expand or expand as fully as the Makers and Lehigh at subsonic velocities. The Lehigh 194gr maximum expansion subsonic and the Maker Bullets. Out of all my testing there have only been two that stand out: From the Wedge to Rainiers to Berrys to Horanday, ect. I have tried just about every subsonic expanding bullet out there. Subsonic rounds do not exhibit a supersonic crack making them quieter when shot through your favorite can.View QuoteFrom what I could see the 200gr subs from DRT don't look like they would expand very well if at all. Please Note : Subsonic loads are ideal for shooting through suppressors because they help reduce the sound signature. This ammunition is new production, non-corrosive, boxer primed, in reloadable brass cases. This ammunition is built for defense purposes and for hunting medium sized game (50 to 300 lbs) including whitetail deer. Performance of this ammunition meets or exceeds FBI Protocol terminal ballistic test requirements and delivers devastating, threat-ending performance. The Sub-X bullet (projectile) features a lead core with long grooves in its gilding metal jacket, which combined with the bullet’s flat profile and the patented Flex Tip insert within its hollow point cavity help it expand reliably at low velocities. Unique powders optimized for subsonic use result in a low flash signature, ideal for either suppressed or unsuppressed performance. 300 AAC Blackout 190gr Sub-X Subsonic Flex Tip eXpanding 20/Box is designed for accuracy below the speed of sound, and when paired with a suppressor, it’s even more quiet.
