Anyone have any great loads worked up for the .270win?

I have a Ruger MKII M77 .270 bolt action. Thanks< !--color-->I have h-1000,imr-4350,imr-3031,130gr bullets

Rifleman, For what you have on hand right now, load 53 to 55 grains IMR4350 with the 130 grain bullets. I have the same rifle and I have got the 130 nosler BTs to shoot well with the 4350, but the seating depth had to be right, more so than should be. I now use 150 grain bullets with RL22 or 4350, whichever the gun likes. All the 270s I have loaded for have liked 4350 with 150 grain bullets, and it is only recently I have used RL22 with the 150 grain bullets. I am getting better velocity and about the same accuracy with RL22.

you, do not have it listed but the venerable load for the .270win is 60grns of h4831 under a 130grn bullet. this load goes back at least 40 years. i use 59.5 grns of h4831 under 130grn sierra gamekings or pro-hunter and shoot 3/4" at 100 yds and 1 3/4" at 200yds.

i forget the velocity on this load but i have never had to shoot a deer more than once with it. they were not drop dead kills but the deer has never run more than 50yds when hit.

consult several loading manuals and start out at the lower end and work up looking for signs of excessive pressure.

good hunting

As with any load development, start at least 10% lower and work up slowly - *** your rifle IS different from mine ***. Having said that, I agree with 59.5grs of H4831 topped with a 130gr Nosler Partition or 130gr Barnes Triple Shock or 130gr Sierra Game King. A combination of the right charge of H4831 & a good 130gr game bullets seem to shoot in just about any .270Win. Get the best group via powder charge changes that you can and then work with the seating depth - you should be able to achieve .75moa or less, just be patient and look carefully for pressure signs. A chrono is an invaluable tool.

Good Shooting.

You've come to the right forum my friend. The .270 is my favorite caliber and I've loaded a bunch of rounds for more than 7 different guns over the past 12 yrs.

I have long custom barrels though so keep that in mind.

Here are some of my favorites:

130 Triple Shock over 57.0 Re19
130 Ballistic Tip over 57.0 H4831SC
130 Ballistic Tip over max IMR4831
130 Sierra game king over max IMR4350
130 Speer over max IMR7828
130 Hornady SST over max VV165
130 Scirocco over H4831SC any charge!

I would work up the IMR4350.



Now for the unsolicited part:



I shoot 150 partitions (150gr Sierras for practice) over H4831. Used to be IMR4350 but H4381 got the accuracy edge (right at MOA in Ruger Mk1). Both are old-data loads, now over book max. I took a bunch of deer with this load before I started playing with other calibers. If any ran more than 50 yds I can't remember it. Except for a few neck shots, all were lung shots; about half the broadside shots dropped instantly.



I started with 130gr bullets but came to see no use for them in a case this big. Funny how 150gr bullets are screaming fast in an /06 but neck that case down to .277 and 150gr bullets are slowpokes. If the 130gr bullets are any flatter-shooting it's negligible on a 8" vital zone. And of course the heavier bullets do better at the longer ranges that supposedly the .270 built its reputation on.



Nonetheless, if starting out now I would try the heaviest Accubonds or Interbonds to have pretty tips to look at.

I am also considering loading H4831. I see a reference to H4831SC. Is that a differen't powder?

Thanks MarkB! I feel like I learned something today!!!

I use 53.2gr IMR4350 with Hornady 140gr BTSP interlock and winLR primers,hornady brass.Chronied at 2900 fps in a 22" remy.mtn rifle.Groups 3shots under an inch @ 100yds.

Hey now... we forgot to mention IMR4064? I've been using 46.5 grains of IMR4064 to push 130 grain Nosler partitions into 1/2 inch groups at 100 yards since I was 14. (No, I'm not turning 15 tomorrow... though I wish.) This load is well liked in my Mauser and continues to prove devastating on the PA whitetail population... that is for the ones I don't run an arrow through in the first season. Nonetheless as previously stated, please be sure to use caution when trying new combos in your gun. Think safe, be safe and always identify your target. PLUS what's behind it. (There's a story... but I'll stick to the Readers digest version on this post.)
