Your Quesion is now answered:
150 gr Nosler boat tailed ballistic tip
Federal large rifle primer
57.8 gr Hodgson 4831 powder
energy.....3050 ft lbs
This isby far the best,most accurant load that I have used in 35 years out of a Remington 700 BDL
Ya might want to work up to that load. I don't have my "Nosler" manual with me but according to my "Hornady" manual 58.7 grs is a max load.
I'm not a big fan of the .270 but I used one years ago, A Harrington Richardson on a Sako L61 action. I don't recall the load, most likely as hot as I could get safely and still shoot well. But my favorite bullet was the 140gr. Prior to the introduction of the 140 gr, I had alway's believed the 150 gr the best bullet for the .270.
It's 57.8 gr not 58.7.. I wouldn't want to go any hotter. 58 gr in max load. You're right with the 150 gr bullet.
I know a fellow older than me that has been loading the 270 for at least fifty years. He used a bowl filled with H 4831, sccops the cae full and taps it down to about a quarter of a inch from the neck, and force feed a bullet in it.. Not something I would recommend, but for curiosity sake a filled a couple of cases with his method, emptied and weighed.. amazingly consistant but some scary.
Jack O'Connors load was 61 grains of H4831 over a 130 gr. bullet. I have used this for many years (approx. 3 decades!) as it does make a pretty group out of my Rem. 700. It has been a totally excellent whitetail round. It is a real full case, but I prefer high loading densities, as I think they offer a safety factor, and maybe an edge in uniformity of ignition.
The current manuals would suggest this load on the "hot" side, so you should start a few grains lower and work up to it in your rifle. In the early 70's, I used a case full of WW 785, at similar velocities, for a few years, also around 60 grains.
I have found quite a variation in case capacity between the various manufacturers of the 270. I am partial to Federals & Winchesters as they have always seemed to be significantly larger than Remingtons.
As a Taxidermist I look at hundreds of Whitetail Bucks every year. I know that I have seen many different ways people judge the size of racks on live deer. I think for the most part they all are pretty close. I'm going to give you some measurements that I have noticed being right on in just about every deer. We have used it in the last couple years and have only been off by about 5-6 inches. We do study the deer while bowhunting so we get a little more time to look at them....
