    .270 Winchester

    Never really thought much of the .270, seemed a weird bore size, but I picked one up a few years ago as part of a package trade and because it was the only kind of centerfire rifle ammo that never sold out at our local Wal Mart during the scare. I put a few rounds of factory ammo though it and set it aside to play with other things, but did pick up a set of old dies for it when they presented themselves cheap.

    This past Winter, we cleared my folks out of their house and moved them into assisted living. Have been going through all my Dad's reloading stuff to figure it out. Dad never owned a .270 I can recall, but there sat a coffee can full of nicely cast Lyman (I think) 280412s, lubed with some kind of black lube that had hardened up over the years. I'm pretty sure these were cast by a friend of his that died about 35 years ago and Dad got some of his stuff. Anyway, I figured I'd try my hand at loading for the rifle. I lightly tumble lubed these just in case and loaded some in front of 11.5 grains of Unique and shot them this evening. Considering the cheap scope and windy conditions and twilight lighting, they grouped alright and didn't lead. The 11.5 grains was starting load in my Lyman manual, but I think I'm going to drop it down a grain or so next time and see how that does.

    Not many cast .270 shooters it seems. The rifle is an old Sears 54, commercial Mauser. Any thoughts or advice? Not sure I want to get into casting for another caliber, but I'll sure use these up.

    I bought a lyman 150 grain mould for the 270 back when they had the huge spring clearance and have yet to use it, picked up an old RCBS .278 lube die a few months back on ebay and now all I have to do is get to it hopefully by fall.

    I load the .270 with an RCBS 150 grain GC boolit, max load of 4198 according to the RCBS book for around 2,000 fps. I think I also used 4227 for some loads. Major disparity in POI between cast and 130 grain jacketed so I've loaded cast very little.

    Many years ago a 150gr Lyman GC bullet over 4227 (unknown gr). Was a great practice load for a new rifle shooter in a left handed Savage 110. My first left handed rifle shortly after we move to New Mexico. I learned the rifle and how to shoot in the high desert. Wish I still had the rifle! Still have the mold.

    I never warmed to it; it's too versatile. Stuck between two of my favorites, the 25&30-06, I've let all three I've owned go. That Sears 54 is a good one to have. I noticed .270 ammo on the shelf during the drought as well. Good luck with the CBs!

    We have a 270 that also just sat around for years and I also picked up a rcbs 150 mold and lyman 122 gr mold but I never played with them till last year. I decided to see what happens and that was the easiest gun to shoot cast in we have. I regret I did not use it years ago.

    I would be interested in what loads you all have found to work in your .270. I have been playing with one but have not found a working load yet.

    270's move pretty fast for cast. I picked up a bunch of stuff and there were some boolitz's. so I haven't got around to casting any yet. After all yearly round count is pretty low. I've got about 500 pc of brass with maybe 30 reloads on hand.

    My 270 up to now has been a jacketed bullet rifle, but I bought a 150 grain GC mould last year. I just have to break the mould in, but there are lots of projects in the queue and it has low priority right now.

    Here are some loads with 130 grain bullets that I have found useful:

    130 grain Winchester Power Point
    RP cases, OAL 3.325"
    Winchester LR primers
    52 grains of H 4350 powder

    Av: 2875 fps Es: 41, Sd: 17

    Accuracy is 1.5 MOA day in and day out

    All components same as above
    54.5 grains H 4350
    Av: 2,995 fps, Es: 55, Sd: 18.5 (for 10 shots)

    Accuracy is just over 1 MOA for 10 shot groups

    My rifle is a Pre-War Model 70 Winchester equipped with a Weaver 330 (3X) scope in Stith mounts. I believe the rifle will shoot tighter groups with a modern scope and mounting system. The Stitch mount has slight play at the objective end of the scope. I'll leave it as is though as it is the poster child of a classic rifle from the 40s and the 50s.

    After shooting this rifle, you'll understand why Jack O'Conner was so smitten with the Model 70 in 270.

    Major disparity in POI between cast and 130 grain jacketed so I've loaded cast very little.
    Poygan,

    That is quite common and to be expected. I have had up to 12 MOA difference depending on the load used. A good aperture or scope sight with repeatable adjustment will solve any issues in zero between cast and jacketed bullets.

    I guess I should have been more specific. I am looking for information on cast loads for 270. I have the Lee 277-135 mold and I am interested in other people's experiences with cast in the 270 at velocities under 1600fps.

    I have several 6.5 molds. I wonder how paper patching one of these up might work? Never tried patching before.

    I have a couple of 270 molds and 270 reloading data if anyone is interested. I have yet to shoot my 270 Encore pistol with cast but have used both molds in my 6.8SPC.
