NR,

First of all if your getting close to 1" moa then that is not all bad. Secondly, instead of trying this and that willy nilly you need to organize your efforts. Run a search and find some info about Creighton Audetts ladder method. It is a systematic way to find the most accurate load for "your" gun with a given combination of components by starting low and gradually increasing your powder charges and then tracking their placement. The "sweet spot" in powder charges will manifest itself as the smallest group.

Actually for deer Jack O'Connor liked the Remington Bronze point, Speer, Sierra, the Western Silvertip in 130 grain and the 120 grain Barnes. This is the silvertip which has a cap of tin and the barnes was a cup type bullet with a jacket of almost pure copper. He felt "some of the controlled expanding bullets didn't open fast enough". Of course he didn't mention the Partition. Being old enough to have read Jack's writings while he was alive I remember the paucity of what we call "Premium" bullets". To get a box of Nosler Partitions was a mail order proposition. If your gunshop had any at all they were likely to be 180 grain 30 caliber bullets. The Silvertip was his favorite large game bullet for Elk and Moose. He felt that a bullet that traversed the chest to be found under the hide on the far side has adequate penetration for those animals. He preferred above all else to put the bullet behind the shoulder possibly angling toward the far shoulder but did not care to aim directly for the shoulder on the side he was looking at. This is not quoated but accuratly brought to you from O'Connors book "The Hunting Rifle".

I started reloading way back when Jack O'Connor was King.
H-4831 was THE powder to use in the 270. They talked about cramming 62+ gr behind 130s, and 60gr behind 150s. O'Connor liked Win cases because they were thinner and had more capcity the most others
I tried loading that way and found that heavily compressed loads would often "grow" in length. Quite often one of these would leave the bullet in the lead when I extracted a loaded round, dumping powder into the action of the rifle.
Bad ju-ju for a lot ot reasons. I finaly settled on 56gr of H-4831 behind 150s. Tight but not compressed.
I sighted in on a target that was two 3" circles, one above the other. At 100 yds I aimed at the bottom one and made holes in the top one. By todays standards this would be pretty sloppy, but you know, that damned 270 killed every thing I shot at.

Hi New Reloader,

I must say, I'm always impressed with Allen Day's posts. You cannot argue with experience, and the 130 Partition just may be the standard go to bullet for the 270.

However, I will say this. The new triple shock from Barnes has impressed me more than any other bullet in the 270...the 130 grainer on Re19, 57.0 grains. I've never been more impressed with any other bullet all around, and I've killed a lot of deer with a lot of bullets. Dead is dead but some kinds of dead make me smile a bit more. And reloading is fun, and there is a bit more satisfaction in killing a deer with something you put together as opposed to buying off the shelf...IMHO.

I've never killed a deer with factory ammo.

If you gun shoots Rem. factory ammo moa, it is fundamentaly sound. Just work a bit on your loads. Good Luck.

Dakota, I had similar results using O'Connor's H4831 data. In fact, I could not even get his max load into a .270 case. I also tried similar charges of H450, and found that it gave serious pressure spikes earlier than H4831. I was able to use 57 grains of H450, but no more than that. Accuracy with both powders left something to be desired also.

I didn't have a chronograph in those days, so have no idea what velocity I got from my 1/9" twist 20" Mann. Schoen. carbine barrels.

I switched to IMR 4350, and found I could get my best accuracy with the 150 NPJ at 53.5 grains, and 55.5 with the 130 grainer. When I finally got a chrono, I discovered that the 130-grain bullet gave 2880 FPS from the 20" tube, and the 150 came all the way up to 2850.

I used the 150 NPJ for all hunting for three years in AK, and switched to the 130 grain when I returned to the lower 48. The 130 is plenty for anything down here except moose and bull elk, and I am still amazed at the killing power of that little .277" 150-grain Nosler Partition on most anything in America.

Eldeguello:
Back in those days I owned several 270's, one at a time. A mod.70 Win, a husqvarna feather wieght, and my favourite, a 1952 Mannlicher carbine. It had a rather high comb that was tough on the cheek untill rasped down. I had a weaver K-V, 2 1/2 to 5 in a Pachmeyer low swing that was inlet into the stock, hiding the screws.Set it on 5p and forgot it.
I shot a lot of Bronze Points till I found out Core-loks were better. When I started handloading I settled on Sierra 150's cause they shot well and were pretty.
I corresponded with Jack O'Connor a little and he guestimated I might be getting about 2800fps with 56gr of H4831 behind the Sierra 150 out of the 20" bbl.
I know it really worked because I killed a trainload of game with that outfit. I was in my mid 20's then and that was more than a few yrs ago.
About 20 yrs ago my oldest son was having trouble hitting game or hitting them right. Good on paper but not on game.
I had a little chat with him and convinced him that the Mannlicher was embewed with special ju-ju. It couldn,t miss.I gave him the rifle with my blessing, and to date he has had a succession of one shot kills.
He doesn't hand load. IN about 1995 he was shooting Rem. Extended range 140's. We chronographed a few at 2660fps from the old Mannlicher. We were hunting the Missouri Breaks in Montana and he shot a very nice Mule deer Buck at a lazered 326 yds. the bullet entered just behind the last rib on the left side and came to rest just under the hide on the right shoulder. The deer dropped in its tracks.
He still has the rifle, says its "retired". I couldn't wear it out, and I doubt he could either. Outstanding rifle and a great caliber.
