Just bought a M70 Extreme in .270 Win. Looking for a some loads to start with. Would like to use bullets in 130 or 140 grain weight. What has worked for you? Please share.

Using a Model 70 Ranger, with an after-market stock, I have shot 140gr bullets from Sierra, as well as the Nosler BT and Accubond, from my 270, achieving MOA accuracy with each. The powders I've used include IMR4350 and H4831, among others, but those two have performed the best, for me. I hesitate to give charge weights but if you follow the load books and try a few different components, I'm sure you'll find a combination that makes you realize the limiting factor is the guy squeezing the trigger. ;)

I use the following in my Ruger M-77 MKII .270 rifle:

53.5 grs. / IMR-4350/ 130 gr. Spitzer Boattail loaded in Remington Cases. Received the best accuracy with this load and the factory loads also group in the same point-of-impact, so no re-setting of the scope.

I've shot most the powders the other guys have mentioned except for H1000 and I've obtained the best results with RL 22 in our Rem 700's. I've wanted to try H1000 but haven't yet, but I've thought that may be a good one too. My #2 has been Ramshot's Hunter and though I haven't worked with it a lot, I think it could give RL 22 a good run as my top 270 powder. I have a M70, but have not worked with it a whole lot, so I cannot say decisively that the results I got in the Rem's would be the same in the Win. But on that note, in the Sierra loading manual, they list RL 22 as the accuracy and I think top hunting load for all 130-150 grn bullets except for one load with the 140 grn IIRC and that was with a Savage rifle. If you check the links at the bottom, one is titled 270 Win load info, I have pics of groups posted with RL 22 and the Rem's.

Remington brass, 60.0 gr. H4831, Nosler 130 gr. Partition bullet, Federal 215 primer. 1" groups on paper and so far about 30 deer, 1 pronghorn, 2 caribou and 1 elk, all one-shot kills from 40 to 300 yds. and only one recovered bullet. Oh, yeah, and 6 prairie dogs (didn't recover a bullet from them either).

60 grains of H4831 and any good 130 grain bullet is THE STANDARD 270 load. If that load won't shoot in a 270, sell it.

I haven't done much load development for .270 Winchester, but I did try out some new Beger 140 VLD bullets today, and they are so far my most accurate load :D

The data I used was from Berger (they'll send data for their bullets if you email them. Seems to be the only way to get the data).

Using H-4381SC I loaded up (close to their max of 57.3gr), in Winchester cases using CCI primers. I used the published cartridge OAL and have yet to play with different distances off of the lands.

55.8 Gr -> 100 yards 6 shot group, center to center 0.45" wide x 0.9" high.
56.8 Gr -> 100 yards 10 shot group, center to center 0.65" wide x 0.9" high, with one ugly flier about 1.5" away from the group.

My .270 Winchester is a Browning 1885 Highwall and it has a Bushnell 3200 Elite 3x9 on it. All shots were fired from sandbags front and rear.

Edit: I also tried 52.8gr, 53.8gr, and 54.8gr but the accuracy was significantly worse for those loads.

Trade it for a 7mm of some sort, hehehe :D

Im kidding, but Chris' suggestion of the Bergers is definetly worth looking into. The more info I find about them, the more I'm liking them.

My favorite load is:

Fed cases
Nosler Ballistic Tip 130gr
RE22 60gr
CCI 200 primer
Lee collet neck dies

I'm shooting this out of a Savage 111 w/Mueller 8.5-25x50 scope with amazing accuracy and hunting results.

Best 3shot group at 100yds is .123"

You can see the 3 shots that are circled (other holes are from friend and non-shooter Brian as marked). There was zero crosswind and you can see that the group split the line pretty good on-center....

Though I've owned several 270's over the years I never really reloaded much for them. One thing I did notice from my shooting experience with them was that, to a rifle, they "either" prefered heavier (150gr) bullets or lighter (130gr.) bullets, BUT NOT BOTH !!! For some reason the rifles that liked the heavier bullets wouldn't group lighter ones and vice-versa. Maybe it was the twist or the inherent nature of the cartridge itself, I'm not sure. I still own and hunt with a very accurate Model 70 and it has an amazing fondness for 150gr. round-nose bullets of all things. Ragged-hole, 5-shot groups at 100 yds. !!!!!!! HD1

My experience is the opposite of yours the ones that I have worked with shooter the 130, 140, and 150's equally well

I load the Nosler 140 grain Accubond with RE22 powder in RP cases with a Rem 9 1/2 primer.

Here's a 5 shot 100 yard group from my Browning.


You can see it was actually a WInchester factory load. However, sometimes the factory loads expand out to 1 to 1.5 ", and they're expensive to shoot.

I get my best consistant accuracy with 55 gr of IMR 4350 130 gr Nosler Ballistic Tip and Winchester LR primers and cases. Sierra Game King shoots exactly like the NBT, so I use that for practicing and occasionally for hunting.

130 Grain Hornady w/ 53 grains of IMR 4350 Shoots 1" groups, 140 grain trophy bonded w/52 grains of
imr 4350 shoots about 1 1/4" groups. This out of a 25 year old savage model 110 with an aftermarket ram-line synthetic stock, and a 20 year old tasco 3-9 x 40 scope.

Have never played with any other loads for it as of yet.

I have also found several powder/bullet combinations in 130, 140 and 150gr that have shot well, from my Model 70. The one thing I never did find was a load I was satisfied with when shooting the 110gr varmint bullet from Sierra. I finally gave up on using my 270 for anything but big game and the only bullet it has seen in the last few years has been the accubond.

how can a load in one rifle be accurate in a totally different rifle.- it may be, but you have too many variables.a 270 is not as inherently accurate as a 222.-my point being- each rifle is a law unto itself.-a good loade in one may be a good starting point in another gun with all due dilligence taken.
