Reloading help for .270 Win

Ok, So I finaly got my reloading bench set up and going. I loaded up some Nosler 130 gr. Ballistic Tip's with H4831sc with CCI 200 primers. 3 loads 56 gr. 57.5 gr and 59 gr. 5 shells each. First load (56gr.) was the best group right at .75 moa and the last load (59gr.) was second best at just over 1 moa. While .75 moa is not bad, I am hoping to get something better! and would prefer it to be more on the HOT end of the scale than the lower end. So now for my question...

What is the next step or load you would try? Diffrent powder? if so what..... Diffrent bullet? if so what.......


Oh yea this will be say less than 500 yrds, and mostly deer sized game with some thick skinned 400 to 500 lb Rams.

Thanks for your help.

Adjust the COAL on your 56 grain load and see if you improve from 0.75 down to a smaller number. I suspect you will see a difference.

Of course, what was the COAL of the loads you shot? How close to the lands? You didn't state those items in your first post.

Re: Reloading help for .270 Win

You didn't mention bbl length or if velocities were measured

It's difficult to get enough 4831 in the case to get decent velocities. Back in the days when 60 grains was supposed produce 3000 FPS MV. Never happened for me in a 24" bbl.

For deer or the thicker skinned stuff you may wish to go with the 140 Accubond. The same MV can be expected as with the 130. BC is better as will terminal performance.

Stick w/the non-mag primer. CCI 200s do well.

If the temperatures you hunt in are close to the temps which the load is worked up Reloder 22 is a great selection. Most certain to get better vel than the slower powder. As always start low and work up cautiously.

Good luck...

The coal is as long as possible to still fit in the magazine. No more room to adjust here without becoming a single shot.

24" bbl. And no velocity was not measured. Don't have a chrono yet. Temps will very from 100 deg to mid teens.

Thanks for the replies! Keep them coming!!

Re: Reloading help for .270 Win

You can back the bullet away more. Load it shorter and see what happens. You can change make of primers and you can go to mag primers and see what happens. Just back off and work back up. Sort your cases by weight. Deburr the inside of the case primer flash hole has added accuracy for me. Uniform your primer pockets. Check your run out on the bullet to case. Clean up the necks of the case to uniform neck wall thickness. Check your shooting form, unless you do EVERYTHING the same the bullet will not strike the same point. I always got between 3000 and 3100 fps with 60 grs H4831 and 130s in 24" barrels. CCI BR2 primers always produced good accuracy for me. You did not mention what rifle you have. If it is not a full blown custom barreled tricked out and tuned rifle you most likely have about topped out in accuracy. It is kind of like what happened to a fellow I know who bought a Weatherby rifle a number of years ago. He could not get it to shoot under 1" groups. He wrote Weatherby about it to see what they could do. He got a post card back with these words. "Weatherby makes a hunting rifle not a target rifle."Don't expect off the shelf rifles to be target rifles.

Re: Reloading help for .270 Win

So if I stick with the 56 gr. Load and just do some find tuning, do you think this light of a load will still have the velocity needed to make clean kills out to 500 yards?

What would be a good fast burning powder that can still tolerate temperature changes in the .277?

Re: Reloading help for .270 Win

I just finished loading my friends Remington 270 Win getting ready for our deer hunt in Neb.. He had been shooting Factory 130 Silver BT and I wanted to load 130 Accubond bullets for him. I started just like you did. I used H4831 since I have had great luck with that powder and 270 Win., I started with 56 grains and worked up to 59.5 grains without succes. I changed powders--H4350 and bingo, 54 grains gave me 3 shots under 1/2 inch. Since my friend said he wanted accuracy over velocity I did not chronograph this load but to say the least he was very happy to get a load that shot under 1/2 inch when his factory loads shot 1 1/2 or more and my first loads with H4831 did not break 1 1/2 inches.

My advise is to either work up your load to 59.5 grains or even 60.0. I know that most manual now show 59.0 as a Max load for 130 grain bullets, or you can switch to another powder and see if it works better. H4350 is good, RL-22 works great in the 270 Win, and I have had great luck with N165 and Hornady SP's in one of my 270 rifles.

By the way this was Remington's cheap 710, (I think is the model number) but I never though that I could get this gun to shoot better than one inch at 100 yards.
