MY Sporterized Parker Hale Deluxe Sporter

 I used data from Lyman 49 for .358 Win using IMR4895 with 225 Sierra Game Kings.

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 of IMR 4895 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.

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

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.

I have 200 new and primed Hornady .303 cases that a friend gave me to make into .35-303. That is a Separate Operation so the Expander and De-Priming Pin is backed out so I didn't push out the new primers.

C&H lists .35-303 dies but I didn't call them to see availability as I already had the .358 Win dies.

Hope this helps.

I still haven't got to shoot this gun or anything else due to our Range being closed from the rains earlier this year. They are saying opening the road by Labor Day but Caltrans is notorious for being FOS so we are hoping.  I'm going to be pretty busy up there after we get back open as I've got several guns to deal with Load Development and Sighting In as well as lots of Shotgun She!!s to burn up on the Skeet Field.
