140 gr 270 bullets

reddnek

I recently bought a bunch of 140 gr 270 bullets (blemished) from Midway .I have no way of telling what brand they are. Can I use reloading data for any 140 gr spitzer point boat tail bullet??? I have on hand IMR 4350,IMR 4320,and IMR 4895 powder,would any of these be suitable???

As long as you use the starting loads and work your way up you will be fine, all three powders you listed will work with the 140's. IMR 4350 is my powder of choice for the .270, it is slower burning than 4320 or 4895. This results in better consistency and accuracy in most of the rifles that I have owned and helped others work up loads for.The following is data provided by IMR, they were calculated with an oal of 3.280.
Powder Start Max
4320 41.5/2614 fps 44.5/2775 fps

4895 40/2627fps 42.6/2768fps

4350 49/2737fps 52/2870

I'd prefer H4831 but 4350 will do. The others are a bit too fast for load density to be very high.

The bullet weight is what you go by in the data, unless the bullet is a solid like barnes etc, then the different characteristics of the material change the data.

I'll go with Justin on this one, H4831 gave up some of the best groups ever using it along with heavy bullets in a 270........

Another good powder for the .270 is Reloader 22. I find it is similiar in burning rate to the old suplus H4831. In other words, it's a little slower than the present H4831. I use it as my standard load in my .270's with the Sierra 130 gr. flat base bullet.

I use Jack O'Connors load for 130gr with 140 gr Nosler Accubond with no signs of excessive presure. They shoot in the same hole as the 130s. I wouldn't have beleived it if I hadn't done it. I load 59grs H4831SC with a Win WLR primer and the Nosler 140gr Accubond. You should start a couple of grains lower and work up for safety sake, look for presure signs.
