Good Starting Loads for 270 win and 357

jomdlcrs · March 19, 2011, 08:13 PM

As I am getting ready to place my order for reloading equipment I have been reading different books on reloading. And I was just wondering what loads would be good for starting out. They will be shot out of a 357 ruger security six and a 270 winchester

H4831 with either 130 or 150gr projectile for your 270Win, start low and work up, where ever best grouping occures which usually occurs 2-3grs below a max load stop there. William

You did not state whether you will be shooting cast lead bullets or jacketed bullets so as I only shoot cast bullets in my .357 Mag. S&W M28, that's what I'll pass one. I'll shoot either the Lyman #358477 (150 gr. plain base SWC) or #358156
(156 gr. gas checked SWC) with one of two loads. For the 150 gr. bullet either 5.0 gr. of Unique for a light target load or for more romp & stomp 14.0 gr. if Alliant #2400. I'll use either Remington or Winchester brass and the standard WLR primer. For the gas check bullet, 14.0 gr. of Alliant #2400. The 2400 load is considered max in most manuals these days. Both loads are very accurate in my revolver. Bullets are sized to .359" BTW. Bullet metal is cleaned wheel weights.

For the .357, try 8.0 grains of Herco with 158 grain hard cast bullets (SWC or RNFP) It's a good compromise between economical and powerful.

What W. Watt said. Try 130 or 150gr bullets and H-4831 powder and work up loads. IMR-4831 is a good choice also, I like H-4831 because it is temp resistant.
In other words, it works better in colder temps. But, they're both good choices for your 270 Win. Good luck in your loading.

....as a new reloader, I suggest you start with jacketed bullets as they tend to be more forgiving and easier for a new reloader to make accurate loads with. Also as a new reloader, I suggest you purchase at least one quality reloading manual and refer to powder manufacturers websites for published and tested loads. Published loads are what every new reloader should be using. Suggested loads from the internet are fine, but always confirm them by referencing a published source which has pressure tested them for safety. Find a bullet and then find a load recipe to match. In the .357 I suggest stickin' with 158gr JHPs. Start at minimum and work your way up. Do not load under minimum or over max listed unless you can verify it in another load manual. If you do not have a chrono, I suggest you use factory ammo to compare recoil, accuracy and primer appearance. Also, at first do not load large quantities of any load recipe until you are sure it performs well in your gun.

And don't start out using H-110 or 296 powder. It has a very narrow operating range.
