Springfield 1903 in 358 Winchester

[youngda9]

I sent off my Springfield 1903 yesterday to JES to get rebored and rechambered to 358 Winchester (3-groove rifling with a 12" twist). The rifle has a 24" 243 Douglas barrel. I have a Timney trigger on the way and will also install a Lyman 57 peep sight with target knobs. The barrel mounted flip up sight and front sight hood will most likely be removed. This 358 will be used to work up a load for the Accurate 36-280B boolit (Lyman 358009 clone with .18" meplat). I've read such great things about JES reboring on here that I just had to try it for myself !

Edit: Probably should've posted this in the Military Rifles forum.

Indeed! What a heartthrob!!!!
This will be one rifle you will likely hold onto. JES does absolutely stellar work. I recently had a barrel board out by him in 35 caliber as well (although I went with 14 twist).
Just wait till you look down that barrel! When you do, keep in mind that he uses a hand operated rifling bench to lay in those perfect spirals.
Simply amazing.

Thank you Larry.

I thought about a slower twist to try for really high velocity out of the 200gr RCBS boolit (NOE clone) but decided that I just wanted this rifle to have peeps and throw the big heavies out of it.

I'm going to start with H4895 for load development since I have plenty of it and it seems to work really well with the 230grain boolits I shoot in the Ruger. Looking for a load around 1800-1900fps I recon with the 280 graon boolit. Should be around 35-38 grains of H4895 I figure.

If I don't get good accuracy with that, I've read (source (http://www.leverguns.com/articles/paco/small_charges.htm)) that 2400 is a good powder with this boolit. 22-23 grains of 2400 should give 1800fps or so. Anyone know if that load would need a filler? I don't want to have to deal with fillers. That's a big reason why I like H4895...a full case is a full load.

I'm certainly glad you didn't, as I might have missed it. Beautiful rifle, and great cartridge.

Take care, Tom
