8-10 feet,and look for signs of unburnt powder grains and bullet wobble.

I like to place a target,flag side out,close to the muzzle. Several of the above listed loads are proven performers in their rifles. How well the bullet seals the bore,rifling twist rate, and bore time all seem to be a factor on how well a load will preform in certain types of rifles.

This is by no means gospel, as the Whisper series of cartridges do shoot well. Many years ago Dr.Mann did very extensive test on bullet shapes and true to form, the round nose bullet is the best performer at sub sonic velocities. If I had to pick just ONE powder for subs, it would be Trail Boss.Ī slow burning rifle powder such as IMR-7828 will not give you consistent SD or stabilize the bullet as you'd like. 308 load uses 8.6 grains but it does not fill the case as well as Trail Boss. It is a solid 1.25' performer at that range, which is excellent for a round nose sub.Īnother excellent powder is Unique. At 100 yards, I simply hold over by just shy of 1 mil in the scope. I also use an OAL of 2.65' My 700 5r throws it at 1040 FPS and it impacts about 6' lower than my supersonic loads form the same gun.

I use this exact same load, but I have been using the 180 Sierra Round nose.I believe it is the Pro Hunter.

Lastly, the search function is your friend, as there is a thread posted regarding the Speed of Sound, ambient temperature is the main factor determining it. ALWAYS TEST FIRE WITHOUT THE CAN ON THE GUN, and look for keyholing. I particularly like round nose bullets in the 170gr to 180gr range, they stabilize out of my 5R very nicely. Don't want any pesky baffle strikes, I particularly like this one, and besides with friends like this who needs assholes. The biggest concern is making sure they stabilize out of the barrel. The next consideration should be bullets, heavier is often better depending on your twist rate and barrell length. Its very bulky, 15gr fills a 308 case (Can't double charge), its easy on the hopper, and very consistant. I have personally tried Red Dot, Clays, and Trailboss won out. I have seen people play with Titewad, Clays, Bullseye, Trailboss, and Red Dot. To eliminate that sensitivity you can utilize a wadding material, but that gets to be a pain. Some pistol and shotgun powders will work but are very case sensitive creating uneven burn rate and a lack of consistancy with POI. MAKE SURE YOU HAVE 30% CASE VOLUME.Įxperimenting with several different powders by many people here have led to many threads on the subject, try the search function and you'll see. The occurrance is created by slowed or delayed ignition, that causes explosive gases to build due to the smoldering, and once ignited causes a high order explosion. Secondary detonation is caused by the use of low density pistol powders similar to Bullseye that when in the case collect toward the bullet end and are not evenly distributed creating an air pocket between the primer and powder. As long as the POI is repeatable and consistant you are fine. FGMM 168 is consistantly 3' low at 100 yards out of my 700 5R, and BH 175gr is consistantly 2' low. It is not uncommon for POI to be about 2' to 4' low with factory ammo. POI shift is dependant on the load (Velocity).

In the little bit of playing I've done, I've noticed the bullet drops about 3-4' at 100 yards from a full pwoer load.Īlso, please tell me about this supposed secondary detonation due to not sufficiently filling the case. I'll be shooting in a DPMS LR-308 so I know they won't cycle the action. Originally Posted By: garandmanI'd be interested in your best loads.
