Just a new person on this site, got into casting this year to give me something else to do. So far, I am impressed with my 45-70 bullets and their groups. Now working on a load for. 308 Winchester using the Lee 150gr. GC bullet. It shoots well at 50 yards but opens up at 100 yards. Looking for some load info forthis one.

Moose56, Try the search function; I am sure there is more data on the .308 than you would ever want to read. Brodie

By the way, welcome to the forum.  I think you will like it here.

there are tons of info on the 308. it is usually easy to find a good recipe for it. of course, there are OTHER things to consider. Alloy, lube and powder being a few. What are YOU shooting it thru? WHAT is YOUR idea of ” shooting well"? Do the bullets key hole? Welcome to the group, I'm sure we can help you once we know more about your situation.

Shooting the Lee 150 grain bullets with a gascheck behind 26.5 grains of IMR4198. It is printing 3/4 inch at 50 yards but opens up to about 4 inches at 100 yards. Not acceptable in my book. I have been shooting them through my Remington 700BDL.

Welcome to the board, moose56.

With 30 calibers, best accuracy usually comes in the 1400 - 1600 f/s range and hunting loads compromise at about 1900 f/s. Lyman lists your load as maximum, 2200 f/s. Your bullet just can not take the stress of loading to that velocity.

HTH, Ric

I disagree on your “velocity limits” Ric- With harder alloy @ 1700-1800 you can still get accuracy in the 308.Stan D, shot a 308 at this velocity and held records for a number of years.With 30 calibers in tight chambered benchrest rifles 2000-2200 @ sub 1/2 MOA is pretty common. A velocity if 2000 fps isn't a lot for a 30 caliber to withstand.My Saiga 308 with an RCBS 165 Sil.with 18BHN range scrap and 30g of 4895 is going 1950 and shoots under 2 MOA (in a semi-auto of all things).Look at the national records and data sheets.

I will agree that 1400-1600 is all you need for up to 200.And is loose chambered military rifles those are good numbers.

George, He is shooting 150 grain Lee's through a Remington 700. In my opinion, for what it is worth, you have to have accuracy before you look for speed. Ric

Welcome, I'm a new member myself. Regarding the .308, I've been working on accuracy with reduced velocity loads for several months. Also using Lee 150 GC and liquid alox.

Purpose was a plinking/squirrel/rabbit/raccoon etc.

Out of 700 + test rounds so far, the best accuracy from a 20” barrel Rem. 600, scoped, runs 1.3 inches at 100 for 5 shots from sandbags. I mix my own alloys, and the best accuracy is definitely with a bullet just a tiny bit softer than wheel weights with 10 gr. of Trail boss. Sized to .309, these run around 1100 fps.

Can't seem to get under 2” with a harder bullet and 2400 powder loads, pushing a 150 GC from 1400fps to 1600, but still working on that. Not sure why yet, but most likely should be a .311 sized bullet, but my rifle has a tight throat, so no go on those.

Slow and accurate is really fun to shoot if you don't mind a bit of arc in the trajectory.

SgtPete, Generally 2400 and light bullets don't mix very well. It really needs at least 190 grains to get consistency with 2400. One and a third inches is pretty good with a light barrel Rem 600! Keep working, it will come. Ric

Hi Moose, If you have any SR-4759 on hand, give 18.5 to 20.0 grs a try in .5gr or less increments. While I do not shoot the Lee bullet, I have had reasonable success with a RCBS 30-180-FN and a 311041 from WW seated 0.030” into the lands. Vels are in the 1700-1800 range, with the better groups for 5 shots being around 1.5 to 1.75 at 100yds off the bench. From a stock sporter weight ADL, I be happy. 18grs smokes cases and I have not got around to trying any charges lighter than 18. Have fun. Michael.

Thanks for the information. I just now finished casting a test batch of 173 gr. from a new Lyman mold using WW. Don't have any 4759, but always on the lookout.
