i havne't had any luck reloading for mine. i loaded up 5 sets of 6 rounds of different charges of imr4350. i'm shooting 140 gr hornady sst.

51 - ok group
51.5 - group gets bigger
52 - group gets bigger
52.5 - group gets smaller
53 - similar group to 51...

not sure what to do next. I've done this twice to make sure it wasn't me. same thing happened.

Should i try different charges? maybe 53.5? i did not have any pressure signs.

Zeus, try AA4350 or IMR 3031, those are the two that I use in the 2 that I use in the 270 mostly. Sometimes, I have toyed with IMR 4831 with decent results.

I would try a different powder. I had sorta similar results. I did the same as you, but with 3 different kinds of bullets in 2 different weights. I get patterns. Factory loads shoot good. I even loaded to the same overall length. I was using IMR4831 as I had it on hand. Just haven't got around to trying different powders yet.

I use IMR 4350 and the closer I get to the max listed load with this powder, the better the rifle shoots. Happened with a Remington 7600 and a Winchester 70

I'm sure you checked gun over every thing tight, i have only loaded 130,150, and 110 gr. bullets and only used H4831,IMR4350,IMR4064. If it were me i'ed take a 130 gr. Bt. and stay with that get it to shoot around 1" group with one of the powder's just switch powder stay with one bullet. You don't want to hear this but my Ruger shoots almost anything i load. I hunt with Rem. Factory Core-Lokt 150 gr.soft point most times. I sight in so i can shoot 130 and 150 with out adjustment, for i use 130 in open fields and am mostly shootin far. If you want or care read some stuff about the 270 by Jack O'Conner and you'll notice the 130 gr. is the bullet for 270's .. Anyone i know with 270's weather Ruger's Rem, Win, Sav., shoot good....later

I have my best luck with a 130 grain ballistic tip or hornady interlock bullet over 56 grains off h4831. I don't think you can beat this load.

So I bought some H4831SC but haven't had a chance to use it yet. I did open it to look at it. It doesn't look much shorter then imr4350. I could not get imr4350 to work well with my powder thrower... how does H4831sc meter better if it isn't much smaller?

I use IMR 4350 and either 53.0 gr. or 55.0 gr with a Speer 130 gr. Sptz flat base or 130 gr. Sierra Spitz. Flat Base. Depends on the velocity I want. I put these loads up in Winchester cases with an R-P 9 1/2 lg. rifle primer. The 53.0 gr. load is the load I use for PA whitetails in a Ruger No.1A with a 22" bbl. Velocity is about 2800 fps. Good luck.

Don't overlook using magnum primers in a standard cartridge or standard primers in a magnum caliber. They will often change the accuracy of a load (for better or worse).

I had a .270 that wouldn't shoot for anything until I tried Reloader 22 and CCI 250's with a 130 Sierra Gameking.

General rule of thumb is charges over 60 grains should have a magnum cap along with certain spherical or ball powders regardless of charge weight....

As a general rule I use slow for caliber extruded powders, aka higher charge volume. I'm currently using CCI 450's(magnum small rifle primers) in my .223, CCI 250's(magnum large rifle) in my .243AI & 25-06, and CCI 200's(standard large rifle) in my 300WSM. The 300wsm would seem to require magnum primers (and I tried them) but in the end it shoots better with standard rifle primers. With the other calibers I've had better luck getting uniform ignition out of the slow for caliber powders with magnum primers. Their was a measurable decrease in both velocity ES & SD when I switched to the magnums.
