I would agree on the Lube. Not as good as it needs to be. Shootaway could order some good LARS lube or even add some Liquid Lube from LARS over his existing lube works too. Messy but works. I do this myself.

I sized and lubed some bullets today with the RCBS rifle lube.This lube feels like automobile grease-very slippery and oily.I will try to shoot them this Friday.

Clean your bore from the old fouling first.

Half of these I shot had the RCBS rifle lube.The group is smaller than the one I shot last week.It seems like the cleaning and/or the lube worked well.
I shot the group at 55yds offhand.

Well you're making progress, but you shouldn't mix lube by shooting some of one lube and some of another lube because you need to isolate what the problem is. You need to shoot a bunch of just lube at a time. Another thing you shouldn't have to clean your barrel at all if everything is right. I've gone hundreds of rounds in a 308 without cleaning and no loss of accuracy because the lube I'm using, my sizing, my bullet, and my loading are all doing their job.

How long one can go without cleaning or before a desired group size is maintained, depends a lot on the condition of the bore.A new bore can shoot accurately much longer before it needs to be cleaned.
Next time out I will shoot only the bullets with the RCBS rifle lube.This rifle has about 4-5000 thousand rds through it.

Hmmmmm....don't know what to say about what you said without tramping on toes. All I can say is that I haven't found that to be true. I believe bores are much smoother today then yesteryear. Partly because many are button rifled which tends to be a tad smoother then cut rifling. Hammer forged is pretty smooth too, but none of this matters since most companies hone after rifling at least to a degree. I've seen some pretty rough old bores shoot amazing well with good accuracy too.

Most factory barrels are hammer forged now; only the custom makers use button rifling. Except Savage.
And todays barrels are very smooth; I know of no major rifle maker who hones barrels, (meaning Lapping). Not necessary, and too expensive. Cut rifled custom makers, yes; because they need it.

not really but a barrel does need a slightly scratched finish.
about 800 grit is right.

I shot 50rds out of the less accurate of the two 308's I have.It looks as if there was a mediocre improvement in group size.I was shooting offhand.My left arm was recovering from an injury and it was the first time in a while that I did anything physical with it-therefore I did not have a strong hold.IMO there was an improvement in group size.I will try and shoot them again next week and report back.

I am guessing that the quality of the cast bullet itself has an affect on accuracy.Many of the bullets I am now shooting were cast in the beginning of the session when the mold was not hot enough.

Yes sir you had better believe that bullet quality has much to do with accuracy. Besides the normal looking the bullets over for full fill out, flat bases, and no wrinkles, the real test for quality is to weigh them. If they vary more the .1 to .3 grains between bullets they aren't cast well.

How much can it affect accuracy?

A lot............ Until you can cast uniform same weight bullets, your accuracy level will be at 1.5 MOA at the best and well above at the worst. Test yourself and your ammo off a solid bench rest. Offhand doesn't tell you much of anything.

1.5 MOA is still good for what I am using them for.If those questionable bullets were to group over 3 inches apart then I would not use them.

I shot my Krieger barrelled 308 today.It is the less accurate of my two 308's.Before shooting it, I gave the throat a scrubbing and removed some of the carbon ring(a ring I didn't know existed until I purchased a great borescope).All I can say is WOW.My first five shots offhand at 50yds went into an inch.I shot the 308 cast using the RCBS rifle lube.They shoot great!!!

So then that RCBS lube seems better huh? I thought it would. That other lube you were shooting wasn't up to snuff for the loads you were shooting. There are other even better lubes out there. To name a few one is LBT Blue. If you order that get the soft version as that's all you'll ever need. The is look up LARS lube.

Now that I got the rifle shooting I can try the beeswax and olive oil lube again and compare it to the group size I got yesterday.That should set things straight.As for now I know the RCBS rifle lube works well.That LBT Blue lube you suggest is quite expensive.

It seems like the load worked well.I did not chronological it but the 10grs of Unique I uses shot accurate and had little recoil.I need to now adjust my sights for this round.Fun shooting with it at the range.It is nice to know that the accurate mould I have for my 308win will do for my Win. mod.94 lever action rifle.

I discovered yesterday that the cast 30-30 Win loads that I made using bees wax and olive oil lube are only accurate until about 30yds.At thirty they grouped in an inch and a half but at 50yds they were all over the place.I will try using rifle lube next time and if that doesn't work I'll try aa5744 instead of Unique powder.

I would go back a step and evaluate the powders available and used then try varying the type of powder(s) and the amount to find an accurate load. I only saw one powder and load listed. Except for one case of pure luck, I have found that one has to search for that magic combo that gives the most precise group. Many other combos may provide perfectly adequate groups also.
Might as well try 5744 in the gun.

Do you have any of the pistol powders on hand.
Do you have access to the Lyman number two cast bullet loading manual?

As others have mentioned, there are a lot of good lubes out there that may well assist in providing better groups also.

Attached is (maybe it will work) Ranch Dog's 165 out of a full on military Type 99 with 4 different loads same powder 50 yards and on sand bags. Note what just a change in hold did for the one group.

There is a lot of info all over the web.

I tried 20grs of IMR 4064 in my 30-30 today and it shot really good out to 50yds.I also tried aa5744 but the load was too hot and the group was too large.Unique is hopeless out to 50yds but it is a fun load at 25yds.

All I use anymore is Veral Smiths' LBT blue lube. It works for me.

This thread is starting to confuse me. In my experience in developing new/accurate loads I take a given load and change one thing at a time. Here we are trying different barrels/rifles, different lubes, different calibers, different techniques..offhand vs. bench and different powders. Seems like too much is going on.

Just my opinion...

Internet search for "pound cast" to determine the diameter of your throat. Have your cast bullet diameter to just fit your throat (example: 0.0005" smaller diameter of throat).

Don't get lulled into thinking bullet diameter should be a flat 0.002" larger than groove diameter. This is just s generalization. You want to target the diameter of the throat, and have your cast bullet "just" slip into it.

Saeco 315 model design is an accurate 30 caliber cast bullet in most rifles. Night Owl Enterprises makes that design, but seem to be out of stock.

Arsenal Molds has a couple of ~170-175+ grain 30 caliber molds with large meplats which are excellent for hunting, and accurate. These are "Ranch Dog" designed bullets. Ranch Dog is the handle of a member on castboolits.com, who designed this mold (he is a retired airline pilot. He knows his stuff). Arsenal Molds will make the mold to your desired diameter for no additional charge. Great custom sized molds for about $70. A good deal.
