what is your .270 win. 150gr. Pet load ?

[Pathfinder]

In the past Ive stuck by 54gr. of IMR-4831 and its worked well in several rifles. This year Ill be doing most of my hunting with a new to me Sako 85 finnlight and I thought that I might change things up. I was reading about someone getting very good velocity with RL-25. What has worked well for you ?

 

[Canadian_Zuk]

MY 2 most accurate 150gr loads are: 53 grains IMR4350 under Nosler Partition and 55.5 grains H4831 with Hornady SST.

 

[Eagleye]

My best load is 150 Partition, chased by 56.5 grains of Norma MRP.
Flirts with 2900 in a 24" tube, and shoots very well in my Vanguard.
I still hunt more with my 140 AB load, using Vihtavuori N165.
Regards, Eagleye.

51 grains IMR 4350 with a 150 partition

I noticed that my 54gr. is ruled as over max by Hodgdon. I cant imagine what the data in the manuals will list 10 years from now.

Using IMR4350.....51 grains ,

56.7gr reloader 22,150gr partition 2940fps
56 gr reloader 22 ,140gr tsx 3000fps
22 inch barrel

56grs IMR 4831 150 serria spbt (over max a little in some new manuals) OK in my rifle.
My old Hornady from 68 listed 57 grs of 4350 with a 150 gr bullet, now that was way to HOT.
The new resent Hornady manual list 54.6 Max. That's about max in my rifle.

CAUTION: Never start in loading with someone elses MAX load...your rifle might not handle it.

I use the same 56gr of IMR4831 charge as NB above does with a Hornady 150gr sp...But only chrono 2800fps through a Remington 700 with a 22 inch barrel.
Myself I prefer a 130gr spbt pill with 59gr of IMR 4831 chrono's @ 3100fps outta the same Remington 700....Over the years I have killed a lot of critters with both loads but I find the 130gr load hits much harder and in real world terms kills with more authority....Not to mention shoots flatter and groups better.
One other thing, I reload for my brother's Sako .270 with 24 inch barrel and use less IMR4831 to obtain same pressure signs and on average another 150fps more velocity...Each rifle is for sure unique...Makes you wonder what kind of performance fellas are getting when they use factory loaded ammo.

 

[H4831]

I noticed that my 54gr. is ruled as over max by Hodgdon. I cant imagine what the data in the manuals will list 10 years from now.

Yes, some of these "Maximum" loads in modern loading books are quite amusing.
There is a Hodgdon reloading chart in the 1964/65 Ellwood Epps catalogue. In that chart Hodgdon's show for a 270 Winchester and 150 grain bullets, 59 grains of 4831, for a velocity of 3105.
I used quite a bit of that loading, but dropped it back one grain, to 58 grains of 4831, in my L61 Sako. Five cartridge loaded in mixed cases and charged with a powder measure set at 58 grains, chonographed with an Oehler, averaged 2919, with a spread of only 22 fps.

 

[Rugdoc]

58 grains of H4831SC and a 150 grain Hornady Interlock bullet sparked by a CCI 200 primer.

 

[beretta boy]

From the late 60's, I used 58 grains of H4831 , Winchester primers & brass, Hornady 150's.
60 grains with 130's and 62 grains with Sierra 90's.

 

[horseman2]

Nosler still lists H4350 at 52.0 grains(max.) as the most accurate powder and most accurate load but the velocity is shown at 2782.
It performd from the start, and the load was worked beyond max. with fasvourable results.
Velocity was never recorded.

Yup, the on-and-on lawyerizing is kind of bleeding many cartridges dry.

I inherited a Brno ZKK600 in .270, along with about fifty rounds of handloads from my father in law. I took apart three cartridges, and checked them against his records. He was running an even 60.0 grains of IMR 4831 over CCI 200's, pushing 150 grain flat base hornady's. He had been using his load for about thirty years. Well, I took a chance and tried his loads in his rifle, and found they grouped right around an inch at 100 yards, were clocking right at 3000 fps on my chrony, and I was not seeing any pressure signs. I decided not to pull his reloads apart and start from scratch; it seemed his apparently way over-pressure load was actually working just fine.
