I sighted in my 270 Model 70 today and it chrono 3230 with 60 gr Rel 22 and the Hornady 130 gr Interbond , barrel lenght 24 inch's. This load is under a inch at 100 yards.  Every deer i have taken with this load was on the spot dead. Great long range load. I also sighted my 257 STW with 81.0 gr of Rel 25 and the Barnes 100 TX. The load is right at 1/2 inch and chrono 3750 . Barrel length 27 inch's. This rifle is very flat shooting  dropping only 3.62 inch's at 400 yards and 14 inch's at 500 yards after being sighted 2.94 inch high at 100 yards. I'm leaving on my Colorado elk hunt in nine days and will use the 257 STW for my hunt.

I also use the 130 gr. Partition. I seat it over 60 grains of RL-22 which is the Max listed load in Lee's 2nd edition. I get 2970 fps from a 22" barrel and shoot 4 shots into .547". I also use whatever brass is handy and have found no variation in groupings.

My old Ruger 77 (in .270) loves 130 gr Sierra Game Kings over 55.0 gr IMR 4350. It also shoots 150 gr Partitions over 53.0 gr of IMR 4350 just as well although these end up 1 inch lower at 100 yards. Both loads are consistently moa in the old Ruger.

morning gentlemen.  i had a load worked up in my .270 using the 130 gr. ballistic tip (molied) that was put together a while ago.  since, i've kinda passed on the moly mess and am going to redo my load using the 130 gr. accubond.  i'm going to use r22 for this development and see there's a couple fellas using it here.  what primer are you using?  the brand's not a concern.  seeing your performance, just curious if you're using a standard or magnum rifle primer.

i dropped the standard primers for a federal magnum primer in my .25-06 and .280ai (both using r22) and the combination really responded well.  i'm going to try the same in this .270 development.

I use CCI 200 primers.  Never have tried a magnum primer with the 270.  We'll be interested in hearing how well you do with the r22 and accubonds.

thanks for the info.

will report something as soon as i have it.  i don't forsee any issues with the mag primers.  and will be happy to get the accubonds rolling in this round.  from all data i've seen, my max load should top out around that 60+ gr. charge.  a decent amount of powder that should respond well to a mag primer.  we'll see.

now i just need nosler to come out with a 120 gr. 6.5 accubond and i'll be set with all my antelope and deer cartridges accubond equiped.

later.  korey

i just finished load development for my 270 and 140 hornady btsp's. tested h-4831, rl-22, and ramshot hunter.

hunter was a disappointment again. i have had zero luck w/ the ramshot line in several different chamberings and have decided i'm done w/ the stuff.

rl-22 did ok. took it to 60 grains and got good velocity and pretty good groups.

h-4831 was my best performer. took that one to 60 grains as well and settled on 58 grains and a cci magnum primer. velocity wasn't quite as good as rl-22 but was close, and accuracy was outstanding.

i didn't get any obvious pressure signs in either the rl-22 or h-4831, but did note the primer pockets were beginning to loosen up after 2 firings at the higher end charges. not real loose, but just enough to notice a difference between the hot loads and their cooler brothers. the ramshot stuff gave no pressure signs at all until i broke the 3000 f/s barrier and then >wham!< pressure signs at 3003 f/s. didn't care for the rapid run up in pressure, and accuracy was lacking...

fwiw... in my 25-06 and 270 loads i use magnum primers. seems those cases are right at the 'breaking point' between needing a mag primer and needing a standard primer. i went magnum because sometimes the weather during hunting season will dip below zero, and i don't care to deal w/ ignition problems on a hunt. however, the 30-06 gets standard primers and does ok w/ those, being a 30-06 and all...

bea175,

That 81 gr of Reloder 25 in a .257STW must be a compressed load?(I'm not familiar with that cartridge.)

Jesus H.Pelosi,that is bound to be a screamer out the muzzle!

And re: using magnum primers,my rule of thumb ( :confused:prob'ly wrong!) has always been to use 'em for any load of 60 grains/powder or more,but they did tighten my .270 groups at less than 60 grains,plus all of the short fat & super short fat magnums we load for (5 total) group better with the Mag primers,somehow....

I should hasten to add this disclaimer: none of our rifle loads are Max loads;usually a couple grains under Max seems to work OK.Having Quickload has been a great help there.

Just my opinion....and most of you folks have forgotten more about handloading than I know!

gnarly... your rule of thumb about the 60 grains of powder needs a mag primer is also one i adhere to. however, like any rule of thumb, exceptions abound - as is the case w/ my 270 load. i do not know where or why i picked up the 60-grain rule, but it is what i use...

I reckon I learned the "if over 60 grains;then use Magnum primers" adage from an older gentleman,well over 20 years ago, who thought he could teach a real knothead (me!) how to handload.

And he  insisted that I refer to the art as "Handloading".

He said ,"Reloading is whatcha do before yer daym gun is empty!"

Recently have read articles from 'loading writers & notables,saying: any long cartridge MAY benefit from Magnum primers in order to completely ignite an (extended) powder column.

And regardless of primer fact or fiction,if I am ever fortunate enough to hunt dangerous game,you betcha I'll use Mag primers!

Recently I began my own research  < insert MickeyMouse here!>  on the effects of heat/cold on my hunting loads.And had even asked about which powders you folks found to be temperature-sensitive...and got great answers!

Here in KY,we do most of our load development in Spring/Summer-and test 'em in 60-95 degree F weather. Don't get me wrong;we target-practice at least every 3rd week,but usually have more time to work up 'loads in the late Winter/early Spring...Yep; that's wrong-thinking! Especially since it's usually 10-30 degrees F when we hunt the beloved deer....

Quickload has made me aware that anything CLOSE to max 'load in Winter/early Spring may be edging up into the Red Zone on an 85-90 degree day.

So forgive my rookie mistakes! And my longwindedness....

I like what cci 250's do with top loads with 7828 and h4831. If I were to use rl22 I would use a mag cap. Anything else wlr large rifles get the call, except ball powders mags are generally called for and I have notice a little tighter groups with that combination.
