308 SUBSONIC SERIAL

30-30 bullets with the nasty BC's will tend to do so.

Generally, shorter bullets will stabilize at lower spin rates (velocities) than longer bullets, hence the flatter-nosed. This powder is not position sensitive so there is no worry with fillers etc.They should stabilize in a 1:10 twist at that muzzle velocity, yes. around 17-18 gn is great in the 303 and x57sized cases (18-1900fps) with 22 gn being brilliant in the 405 Winchester under a 320gn bullet for 16oofps)Д«lue Dot is the most versatile powder in my cabinet and have used it very successfully in cases as small as the fireball case and through to and including the 404 Jeffery. 20% is the starting load and 50% is the max load. I have used it for cases in varying sizes and it will work for the 375 as well.ДЇill a case to the mouth and weigh the powder. 'A good powder to use is Blue Dot which has a formula for all case sizes. I have never tried it so use it AT YOUR OWN RISK: Here is some information I picked up somewhere (I don't think from Seafire). If the bullet was too unstable, you could have a baffle strike which would not be good for the suppressor. Most 308 Winchester rifles have a 1:10 or slower twist which may or may not be fast enough to stabilize a long heavy bullet. To shoot subsonic requires a heavy bullet (I go with 220 grainers) and my rifle has a 1:8 twist.

I have a 300 Blackout in which I shoot subsonic loads. He says he has had good accuracy with them. There is a poster that goes by Seafire on another forum who had come up with Blue Dot loads for a bunch of rifle cartridges you might ask him. Because why else would someone want a suppressor other than to murder people?

I live in NY and owning a suppressor immediately means that you are a serial killer and/or assassin. It would still be fun with a suppressor though. 308 and stopped using subsonics because standard velocity killed things SO much faster. Grain based fillers will clump from moisture and turn to cement in the case and when it is fired, it blocks the case neck until it is cleared out of the way, at the very least, it will lead to terrible accuracy, at worst it will spike pressure ridiculously.ДЄlas, I no longer have a. Only use dacron or similar stuff that is made for the purpose. What I will say though it DO NOT USE Cream of wheat or a similar substance as a filler. Sorry, I cannot give you data for somchem powders. It took about 15 grains to completely fill a.

IMR just states that you leave an air gap etween the bullet and powder and you cannot possibly overcharge it because it is so fluffy. It is too bad you don't have access to TrailBoss powder, as it is PERFECT for subsonic rifle loads. I don't know what you are planning on hunting with them but subsonic bullets typically will not expand as they are moving too slowly so I personally used to limit myself to coyote sized animals (<50-70lbs.) If you don't want to shoot lead, look to round nosed 150-180 grain copper jacketed slugs.

Flatnosed bullets will kill better than the round nosed variety, but your speed will be so slow I am not sure it will make much difference. I don't remember what twist rate mine was but I think it was a 1-10' or a 1-12' so going heavier than 200 grains may be totally out at subsonic velocity as the bullets will not be moving fast enough to fully stabilize. Also, you will not need as much powder to get the same velocity with cast lead as they are softer and lead is a natural dry lubricant (which is why it was used in gasoline for so long). Cast lead blunt projectiles are as short about as any bullet can be for its weight, and therefore will be easier to stabilize in a standard twist. I think you will find that Blunt Nosed GC lead bullets will work best in the 150-180 grain weights.
