I have used MR 3100 quite a bit in my 308 M1 launching the Lee 200. It's burning rate is very close to 4831 so start with that data. In my rifle 37.5 gr gave a bit over almost 1900 fps, perfect...

My notes say that 19 gr. Green Dot with the above components except a WW hull gives 1100 FPS and good accuracy.

My data says that mixed brass, CCI 41, Lee 155 and 19.0 RL7 gives 1747 fps with good accuracy and perfect function in my 300 carbine.

I have fired buckets of the Lee 155 through my Blackout using AA1680. I use 18.0gr, OAL 2.060 and CCI 41 primers. This loads averages 1768 fps out of my 16", 1 in 10 barrel. So far it's also the most...

I have had fantastic results with the Lee 155 .310 bullets and 18 grains of surplus WCC 680. Velocity is 1740 out of my 16" 10 twist barrel.

I wanted to see what a 10 twist Blackout would do so I took an old take off Win 70 barrel in 30-06 and carved it into a AR barrel. It shoots light bullets great but the interesting thing is results...

Weird. My normal 9mm load is the Lee 125 RN over 4 gr Green Dot. This clocks right at 1080fps so it's not screaming but I never see leading.

I have fired 10s of thousands of cast bullets through factory Glock barrels and have never had a bit of trouble. Those hard, smooth factory barrels lead less and give overall better performance than...

After fighting leading in both Wolf and KKM barrels I gave up and put the factory Glock barrels back in. Poof, no more leading.

Have you chronographed that load?

My current M1 load is LC 66 case, 32.1 gr IMR4895, Lyman 311299 fired by a Winchester Magnum cap. OAL is 3.300. The use of a magnum primer cut velocity extreme spread in half and cut group size...

OK, that makes sense.

I'll increase the charge and let you know what happens.

Could you elaborate on that?

My "alloy" is whatever I dig out of the berm at the range. I quench out of the mold but they run soft. My mold throws bullets that measure .3095 on the base and .305 in front of the first band. I...

I hope yours shoots better than mine. The best I was able to get was with, believe it or not, Wolf HPs and they would stay inside 12 inches on a good day. Cast bullet accuracy hovered around minute...

I knew it was too good to be true. I fired this load offhand for the first time today and it was just a little too soft, failing to lock the bolt all the way back about half the time. It's never...

In a year or so, once everyone has so many primers stacked in the basement that the slab starts to crack, the price is going to plummet and they won't be able to give them away. $50 sleeves, here we...

After years of trying to find a good shooting cast load for the M1A I recently tried SR4759. I have quite a lot of this powder and it's my propellent of choice for bolt rifles but for some reason I...

Nope, I use standard FL dies in both. The SB dies are for those tight chambered bolt guns.

In the '06 chambered rifle I use 30.0 4895, Win LR primer, Lyman 311299 and any case I can get my hands...
