Home Forums Reloading Big Game Rifles 270 Pre 64 model 70 loads

Went to the range this past weekend after getting all of the copper out of the barrel. I tried several different loads and bullets. I ended up getting very good results from 54 grains of reloader 19 with a 130 grain Sierra. I shot a 5 shot group with this combo and it was just inside an inch at 100 yards. All of the loads I tried with the Sierra's was inside 1.5 inches with different powders. The other bullet I tried was a 130 grain Nosler Ballistic Tip, my gun just doesnt like them, I didnt get a group inside of 2 inches with the Noslers. It doesnt make sense but I am going to stick with the Sierra's.

Well whaddaya know!!! I just knew that "hunk o' junk" would shoot. Congrats and you might play a bit with seating depth or even another powder for the Ballistic Tips. Anyway, congrats.

My post-64 Ranger .270 likes 130 ballistic tips (or Accubonds) over 60.0 gr of H4831SC. 3 shots in 7/8" at 100 yards with the bal tips.
I just got this rifle last Friday, and I have not yet shot Accubonds in it.

I know the IMR powders are not real popular, but I have had great luck (at or just under MOA) with 130gr Partitions 57 grains of IMR-4831 and a 210 Fed primer in around 6 different 270's including a Pre-64 FWT.

If you get a chance, try RL22 with the Pro Hunters.

I just went to the range again last night and had even better results with 47.0 grains of IMR 4064, 130 grain pro hunters and shot a nice tiny cloverleaf, all four shots were touching.

Nice. I've not tried that powder but have had excellent results with it in other rifles. I know a guy who had had excellent results with an '06. Seems to be a very versatile powder.

6.5:Before RL 22 came on the scene,and after stocks of the old H4831 dried up,IMR4831 was THE powder in the 270Win.Shot piles of it and used the stuff in several 270's.It is still an excellent choice but not many talk about it these days.I have a 7 Mag that loves 66 gr with the 140 AB for over 3200 fps.Good stuff.

centralpa:Glad your rifle shoots now!If you want a load with the 130 partition,sneak up on 59-60 gr of RL22 and the 130 Partition.IME if the rifle shoots a Sierra, it'll shoot the partition.But sometimes the Partition needs a hotter boot in the ass to upset the base in to the grooves of the rifling (obturate).Try it; it may shoot well.

60-RL22-130 Partition has been one of my standard 270 loads for years.

Bob, here is a bullet question. I have never used the partitions, I was told that they are not the bullet of choice for PA sized whitetails. I know they are the bullet of choice for larger sized game, but do they expand enough for whitetails?

Centralpahunter this is not directed at you personally, you just brought up the subject.

How long will it take before folks realize that the front end of the Partition, at least in the small to middle sizes, is deliberately made soft?

No experience here with the 270/130 but I use a 308/150 NP for deer with excellent results. I use a mild but accurate load of 3031 to get to 300 Savage speeds. Very little meat damage with quick stops.

central:Mathman is correct in his post below.They are designed with a "soft" front end,and expand well at both short and long range.Jackets vary in thickness,hence toughness, between Partitions in different weights and calibers,but 130 gr Partitions are suitable for a very wide range of game IMO,and work as well as anything else on deer of all sizes.

I understand where some guys come from when it comes to whitetails because Partitions expand very quickly upon impact and at close range will blow off the front section back to the partition,which presents a small frontal area and small exit,leading to the erroneous conclusion that they "did not expand".This is not true as everything between the holes is generally a train wreck.

I have shot coyotes with them and seen very extensive damage I have also shot scores of pronghorn bucks and does, deer of all sizes from smallish ones to very large bucks at all sorts of distances,from 20 feet to as far as 400 yards, with the 270 130,and 284 140,and 100 gr 25 caliber,and they have been very reliable.I have even shot woodchucks with them

That said,are they necessary for deer? No,standard cup cores work pretty good on deer,too,but IME no better than a Partition; but I like one load for my rifle that will cover a pretty wide range of game,and Partitions do that.I would prefer them over other stuff when ranges can be either short or long;in brush and open. I use them here in New England as well as the west,and were I coming to Pennsylvania to hunt, I know what I'd use.

If you whack a deer in the chest with a Partition and don't kill him, ya didn't whack him in the chest

I brought it up because I thought you were having trouble getting them to shoot,but may have misread your post.If so, sorry about that.

I've shot 3 deer with 165 partitions out of a .30-06 here in PA. None of them took another step. I've shot a lot of deer with cup'n'core bullets, but very few dropped like the ones shot with partitions. 150 Accubonds do about the same thing.

Rich: I'm at a complete loss for explanation when someone has a problem with the terminal performance of a Nosler Partition on a deer,and similar stuff.Some of the stuff I hear and read is like Grimms Fairy Tales.....

Bob,
I bought a box of the 130 partitions and tried your load, not bad at all. I got .75 inches with two different 4 shot groups, I think I may stick with this load, I also bought a box for my daughters 243 in 100 grains, it shot .25 inches with two different 4 shot groups. I may give them a try in my oldest daughters 25-06, I am just not sure what grain to get them in for that caliber.
Thanks for the info., needless to say, I am extremely pleased with the results in the 270.

central: 3/4" from 1.5 inches is a good improvement,I think.

I assume you tried the RL22 load,and I'm glad it worked for you. It usually does in a good many 270's.H4831 works very well also,and sometimes ( rarely) a rifle will show a slight preference for one over the other.

I think you're done with the 270; you can use the Sierra for practice, woodchucks,etc,and the Nosler for hunting.You can try shaving groups some more, but not much will be gained.Try the load at 300 yards, if you can. I think you'll like it there,too.

For the last 50 years I been filling a case with some old surplus 4831, about 62 grs, the old Jack O'Conner load and getting a tad over 3200 FPS in my long tubed M-70 pre 64 std. wt. just like Jack did.

You can't find that powder anymore and I bought a 150 lbs SS keg way back when. Today I would use 59 grs. of IMR-4831 or perhaps the short core stuff, it should work great..The 270 and 4831 are kinda like bread and butter..

My favorite bullets have always been the Nosler 130 gr. but about any bullet works well as the caliber has been around long enough that they pretty much have them perfected to its obtainalble velocities..About the only bullet I didn't like was those damn Remington bronze points, they either slammed them to the ground or they ran plumb off!!

Ray: I've seen those bronze points work....nasty! Never saw one pencil but have not seen many used either.

I have a sneaky hunch that IMR7828 MAY be more along the lines of the old 4831 you have and might work well in the 270,but have never messed too much with it to find out

Godamighty, another guy with a pre-64 in 270....BobinNH was a big help to me early on with mine (it was posessed by an Elmer Keith deamon or something). Mine will be shooting a 130 grain Partition this fall behind 58.5 - 60.0 grains of H4831 SC.

Bob, you mentioned 60 grains of RL-22 under a 130 gr NP. I have not checked the Nosler manual yet, but is that a hot load??? As you meniton that being your go-to load, I may want to see if mine likes this....as you know, she's a 1949 vintage.

Have a great day
