Lyman 357443 in 35rem.

[augois]

I was digging through my cabinet, and found a Lyman 357443 mould that I have not used. I thought this might be just the ticket in my 35Rem. to rid the world of the pesky dirt clod population. The rifle is a 1951 Marlin 336sc. The boolit is a 158gr FN plain base design. I would cast it from WW alloy. I will be looking for velocities in the 1400-1500fps range. Since it is a plain base design, should I water drop these, or do you think air cooled would be sufficient?

My Marlin shoots cast bullets quite well, but it seems to have no throat at all, and I have trouble chambering many designs. Still, the groups that I have gotten that were under 3/4" at 50 yards make playing with it worthwhile. In your case it sounds like you have a pre micro groove gun, and that would be different. If your bore is reasonably smooth I think air cooled wheel weights would be fine at those velocities. I am shooting the gas checked RCBS 35-200 with the same load as the Hornady 200 gr roundnose, and have had no leading so far, and great accuracy. I have shot the Lee 158 RNFP crimped gently over the ogive with up to 11 grains of Unique with no leading too. I've used boolits sized at both .358, and .359 with good results. I just found a mold for the Lyman 358311 160 RN, and am anxious to try them since they will chamber when crimped in the crimp groove. I guess I'm going to have to trim some brass for use with the other boolits I like. :-)

From the basis of your question, your thought process is all wrong.

You need to think about what powder you are going to use to do what you want to do. If you are going to try to reach 1500 fps with bullseye, then by all means water drop them. If you want to try and use 4227 on down, then I would stay with ACWW.

You always hear about how its about matching hardness to pressure. That's only half of the story.

It's also about the "rate of pressure" combined with bullet weight because a heavier bullet is going to have more inertia. You can take a bank vault and push it closed with one finger. But if you try to kick it closed, you will break your leg. Inertia.

Bass said what I was going to, only his makes sense and my explanation is gobbldy gook.

So, if I understand this right......If use a slower powder, and give the boolit a gentle push then I should be okay.

Try that bullet AC'd first. Accuracy will depend on how far out you can seat the bullet. You will want to minimize the amount of bullet below the neck. Unless you plan on a wad or filler the powder will adhere to any lube below the neck. This in and of itself can cause problems. Quite frankly while I've not used that particular bullet I have tried several other cast .38 pistol bullets in my .35 Remington (a M91 Mauser with 26" Shilem 14" twist barrel). I've not found any decent accuracy above 1200 fps with any PB'd pistol bullet. I define that as less than 1.5" at 50 yards or 3" or less at 100 yards.

I do get that accuracy with a 358156 GC cast of WW=2% tin and WQ'd over 22 gr of H4227.

However best accuracy has always been with Bullseye powder and velocity under 1200 fps. With 358477 over 5 gr Bullseye velocity is 1094 fps with 1" groups at 50 yards. Lee's 356-120-TC over the same 5 gr Bullseye runs 1166 fps and normally shoots sub 1" at 50 yards and 2-3" at 100 yards. That is my most often used plinking load in the .35R. Note that the 358477 is equivelent to a +P .38 load and the 120 TC is equivelent to a 9mm load. Both those bullets are with AC'd WWs+2% tin. Lube is Javelina.

definately do not start with 13 gr unique and acww's.
unless you wanna see how far down the bbl lead will go.
see what bass said above.
i believe i would go the water dropped route and a slower powder to your velocities.

With 6 to 8 gr. of a medium-fast pistol powder - WW231, UNIQUE, 800-X, AL-5,etc. you can get fine accuracy with the .35 Remington. That particular bullet should do well also, although I have only tried it in the .357 Mag with 2400, and didn't fool around with it much because it seemed finicky to load with the very short nose and lots of lube - messy to size and load.
Why do you need 1400-1500 fps? The dirt clod doesn't know how fast the bullet is going. I like the above range for pistol bullets becasue they are accurate and pleasant to shoot, so I can use them to instruct young shooters and novices including women.

[augois]

I don't necessarily need 1400-1500fps, it was just sort of a ballpark figure.....Let's just say I want more than 800fps, and less than 1800fps.
