Reloading the .270 Win

[Oldtrader3]

My .270 Win seems to like the 55.0 gr IMR 4350 load just fine. In my Model 70, this load has been shooting around 3/4 inch at 100 yards for the past 40 years with 130 grain Nosler Partitions. No reason to complain about that performance.

Not at all Charlie... Not at all!

What do you shoot in yours Pat?

For what ever it's worth, for all the 270 lovers on this site[thats me] If you have not already read this great article on the 270, you owe it to yourselfs to take 5 mins and read this one . Written by a guy with thousands of kills to his credit that has seen it all.
After almost 40 years of guiding we have come to the exact same conclusions, as he did. This is worth the read!

I have read that a few times, I like Ross Seyfried a bunch, also the 270 Winchester. It does alot of things well. Plus, it is easy on the shooter.

That's a great article, the 270 is a great one which is why it has lasted so long and done so well over the years. Cartridges like the 260 Rem and similar rounds, 270, 7mm-08, 7x57, 280 and 30-06 are capable of a lot more than people think when loaded with a good bullet in the hands of a person who can shoot them well.

Depends on the target Charlie. For basic summer fun and practise I load 49.5 of IMR4064 and 130gr BT's. Super long brass life and easy to shoot in a T shirt. Plus it makes mince meat out of groundhogs ( when I used to live in Ohio).

For whitetails I run the same powder charge but swap out the BT's for Partitions.

For Elk and Mulies I run 52gr of IMR 4350 and 150gr Partition Gold Moly free's. This combo is just plain awesome in my opinion. I have three recovered bullets ( 2 from backstop at range, one from an elk). Average retained weight is like 138 grains. Just an awesome bullet.

I DIG those 150 grain PT Gold's in my 270 WSM..

Charlie; My only complaint is that I cannot find IMR-4350 anywhere. We have a lot of reloaders in Wash state buying it all up. I see H-4350 everywhere. Guess people don,t know how good it is. I picked me up some . I,m going to give a go. I just got back from Idaho where I found cci-200 primers at Black Sheep sport shop. Can,t find cci-200 nowhere in my area. That place is stocked up with everything. They had every powder you want except IMR-4350.

 

[Oldtrader3]

Get some Hodgdon's Hybred100V. It is just a little bit slower than IMR 4350 but not as slow as 4831. I use it in the .257 Roberts and it is accurate and fast, plus it meters great. Nobody knows what it is and several dealers still have some in stock. I bought another pound a few days ago when I could not find any IMR anywhere.

 

[hubcap]

Good point Charlie. I,ve seen H100V everywhere I,ve been. Its on my list. I can see real potential in the .270 and 30:06. The good thing is every store has it because no one knows what it is for. Thats a good thing.

 

[Oldtrader3]

What the heck, if it will do the job in the .30-06 and .270, plus it meters really well.

 

[DrMike]

I would think H100V will perform quite well in the 270; it is excellent in my 280 with lighter bullets.

 

[hubcap]

I think it will work just fine Dr.Mike. I will find out within a week or two. The only thing I will need is load data. Does any one have nosler 7 manual with load info for nosler 130,s using H100V ?

Powley Computer for Handloaders was a cutting edge tool in the 60's. Quickload today provides the reloader another cutting edge tool. I used to read reloading manuals at bed time and fall asleep working out solutions on the Powley Computer. Now I read information to the wee hours of the morning comparing data generated in micro seconds. I am a happy man :mrgreen: rofcrs

 

[Oldtrader3]

I used to do the Powley Computer calculations on my trusty slidesrules as well as, back in the 1960's when there were no alternatives. Actually the powley still has uses and I use it occasion for case capacity to bore ratio.
