Britrifles: Thanks for showing those pages it was much appreciated!
I used data from Lyman 49 for .358 Win using IMR4895 with 225 Sierra Game Kings. Starting at 44 gr for 2180fps 38,700 psi 45 gr for 2230fps 40,880 psi. My standard load for my .308s with 147 gr M80 Ball pulled bullets is 45 gr of 4895 for 2700 fps only load I have ever used in my Ruger Scout Rifle. With 250 gr bullets Starting at 39gr for 1980fps 40,200 psi 40gr for 2020fps 42,475 psi The highest that Lyman 49 goes for .358 Win with 4895 for 250gr bullets is 43 gr for 2180 fps 49,300psi So apparently they toned those loads down considerably as Speer's starting load is 45 gr? This is exactly why I was trying to dig up any info for the .35 Win that was out there as that cartridge more closely resembles the .35-303. I know that powders change slightly from lot to lot . WW2 Military Loads for .30-06, M2 Ball for Garand's ranged from 45-48 gr depending on the lot and they were tested for velocities before the run was started, so they would end up the same or very close to 2700 fps so that the trajectories of the bullets would match the graduations on the sights. The current Hornady Manuals have a separate section for Garand Loading. Anyway, thanks for your input, the screen shots of the manuals were a valuable resource. Randy

You’re welcome Randy.
The old data for .358 Win seems stout to me. Looking at current data for .308 Win on the Hodgdon website for a 215 gr bullet, IMR4895: Min 38.0 gr, 49,900 psi Max 41.0 gr, 60,900 psi These would be piezo peak pressures and not CUP. I don’t know how a larger diameter bullet at the same weight affects pressure (.358 vs .308), perhaps it increases case volume and reduces pressures somewhat, explaining the higher charge weights. Hodgdon online data also has .358 Win, for 250 gr Bullet, IMR 4895: Min no data Max 43.0 gr, 51,200 CUP So indeed, the .358 250 gr bullet has a higher max charge than a .308 215 gr. Bullet! I’d probably load your .35-303 with 250 gr bullet starting at 36.0 gr then work up to maybe 40.0 gr. Stop if the bolt handle sticks. Regards, Geoff |

I will be starting with the 225 gr Sierra Game Kings and a 250 gr Cast Bore Rider Boolit from Accurate Molds. If there is the possibility of a moose hunt in the Yukon in my future I'd surely work up a winner with the 250 gr Game Kings.
Will be using 5744 for the Cast Boolit and I have enough experience with 5744 and Cast Boolits to be able to work up a load safely. I already use it in .308, .30-06, .303 .45-70, so the .35-303 wont' be much of a stretch. You simply start below and work up until the Trajectory becomes useful and not too much Recoil. For my .45-70 with a 325 gr RCBS .45-300 FNGC I started 25 gr as recommended by Members at Cast Boolits. That was useless so I went up to 33 gr in 2 gr increments. 33gr yielded a usable trajectory for Short Range Silhouette, with a tolerable level of recoil. I could shoot 50 in a morning and not hate life. I tried 35 gr but the Recoil increased with no significant change in trajectory. I'll do the same thing with this round. The Boolit from the Accurate Catalog is Accurate 360-250D Randy

I also printed out all your pictures to include in my .35-303 Load Manual. ;>)
This is the most useful info I have been able to find in one place during this whole thread. Thanks again!

I knew these old reloading manuals would come in handy some day, glad I could help Randy.

So I just received my new Boolit Mold from Accurate Bullet Molds for the 35-303.
It is a 250 gr Bore Rider style Boolit which should feed well from the magazine as the nose section is about twice as long as the Lee 358-200 boolit. As you can see the mold is Machined Brass Jewelry! I will cast a bunch of these up this weekend and get them sized and loaded up. Will be starting at 26 gr of 5744 and working up until the velocity is between 1700-1800 fps which should be the sweet spot for this type of Boolit. We'll See Randy

Looking forward to hearing the results. What alloy will you use? 5744 should be a good powder choice.

I cast just about everything from regular Wheel Weights. I got a bunch of wheel weights from a guy who worked for Sears Automotive for decades. I got 11ea. 5 gallon cans full for $20. @1100 lbs.!
I smelted all of it on a Memorial Day back when, and when I got to the last can I dumped it into the pot and it was half full of Gear Oil! It did belch smoke for about 30 minutes and my wife cussed me for the rest of the day! Stunk up the place pretty good! Haven't done that since? Plain Wheel Weights are just easier than futsing with a bunch of different alloys. I get really good results because most molds are cut with dimensions that result in perfect sizes with WW. Most hardly even need sizing. This first batch will get sized and hand lubed so I don't get Alox in the die. After that they will get PC'd and ran thru the die to size the driving bands and install the Gas Check. He cut the Bore Rider section on the minus side of the the tolerance so it should drop at .348, which with the PC will be right at .350 which is the bore dia. of this Barrel. Grooves are .358. I may put some of these in the Lathe and Drill for HP's. Won't need that many as I have the 225 gr Game Kings waiting in the wings. Randy

It took the mold about 30 pours to start producing good Boolits. After everything got heated up and running right it made this one. I ran it thru the sizing die and installed the Gas Check. The driving bands were only about .0005-.001 above the .360 sizing die so not much happened to them.
 I loaded one into an empty case and it fed OK off the magazine. Randy

Exactly what you want. Looks good. I assume you will lube the grease grooves? What groove diameter is the rifling, .358? |

Yes the grooves are .358 on the nose. JES Reboring did the barrel and he is good.!
I will probably Powder Coat these Boolits as I have had really good luck with PC in Rifles and Pistols. There is no leading with PC, Gas Check or not. but the cool thing is that after shooting a bunch the only thing left in the barrel is the gun powder residue from the last shot. The next ones will get the Gas Checks installed after PC ing. Randy
