fellas just got the dies an projectiles for the 270win... only.ptoblem is im going to use Vargrt to beg with, a 130gr bullet will do.about 2800fps...
I want to hear what you have to say about that, in general and mostly for paper but if all goes ahead accuratly certsinly be using on fallow deer....

thanks

Yeah rightio, im going to do some testing an see how I go for a decent accuracy. I might be able to get around 2900 with a max load but see how the pressure signs are by then.

Im actually thinking that having the 100yr velocity wont hurt, especially with the cup an core Corelokt projectile, which isn't the hardest projectile around by any means but may penetrate a little better!?


I also read up on a google search about something along the lines of with a 2700fps start , the drop at 300y was around 15 inch and with a 3000fps the drop at 300 was 11inch... so that doesn't really worry me an I doubt shots will go over 300 very often.


Was hoping to load up some rounds tonight but I did forget the Macrometer and cant be 100% my brass is short enough to be under Max length, although its only once fired brass!?? :/

hopefully tomorrow.

cheers

I load 110 gr vmax at 2900 fps for my buddies 270. Small game still turns inside out. I know this is not a deer load but it's what his rifle likes and he couldn't afford to play with other powders at that time. I'm sure a deer won't notice the difference in speed of your 130s.

At 300 yards the drop my be only 4" difference but the energy delivered will be a lot less
 
The targets and Fallow Deer will never know the difference, and your bore will last longer. I routinely load mild to mid range load data for my rifles, they generally also give you a larger safety window for pressure on really hot days in the tropics- powder dependent of course. Sounds like you're still pressuring out, so that benefit won't be there, but the loads will certainly work.
 
Are you doing this WL because you have a bunch of 130 CLs and want to use them up? If not why wouldn't you go to 150s and the lower velocity but better BC and energy on target? No critisizm, just curious. Or is it a powder limitation thing?
 
A 130 will kill those wee deer with no fuss. A big buck only runs 200ish pounds live weight. Our whitetails weigh that empty.
"...110 gr vmax..." Those are totally unsuitable for deer sized game. They're varmint bullets.
 
cbfmi - i just purchased the 130s but the limitation is more so the powder. Im tryin to put as many calibres as i can into the 2208, but if the tests dont give me the accuracy im after then at that stage i will move to a better suoted slower powder an also possibly change bullet weight.

You may not be giving up as much as you think. Hodgdons site has Varget and the very similar 4064 within spitting of some of the slower powders. I mention 4064 because the listed speeds are nearly identical.

When I started reloading many years ago the .270 was my only rifle and JOC was the supreme authority on all things .270. I had a book of his that mentioned in passing that he had found a load of 49.5 grains of 4064 typically gave consistent accuracy in many sporters so I went with that. (load is 2 grains over today's Hodgdons online data, take that for whatever you want) That load followed me around through many .270s and I can guaranfriggentee you that no animal ever came back to life over 70-80 fps that may or may not have been missing.

Not sure where you are getting the 2800 fps from, but I think you should do better than that with Varget and a 130gr bullet. That being said if you do get 2800 plus out of it you will be fine. just make sure you know your hold over at longer distances. Full load 270 is lots for small deer.
 
WL, I see where you're at, using the varget as your constant it would be better suited to 130s or lighter, just not the best velocity even though it may be a max load, kinda like using 4350 in a 7 mag with 175s.....usable but definately not highest velocity powder suitable. If you can get 27-2800 and good accuracy it should be just as lethal as a 260, 6.5X55 etc.
 
Where did you get the 2800fps number from? According to Hodgdon's web site Varget should push a 130gr TSX to over 3000fps and a 130gr Hornady to over 2900fps out of a 24" barrel.
 
Well I actually loaded up some rounds with 43gr up to 45gr an shot them just now. I'll post up some photos an such soon!

Heres where I got that number from

http://www.adi-powders.com.au/handloaders-guide/rifle.asp?Calibre=270+Winchester

copy N paste from same page

130 AR2206H 24" 42.0 2780 - 45.0 2920 -
130 AR2208 24" 43.0 2795 - 46.0 2930


Accuracy is definatly there.... I think im happy to sit on 45gr for now an do some more target shooting to make sure things are consistant!

pics to come

Ok so Today I had my Remington 700 , out on my backyard "Range"
Im setup at 50ms for now to make sure hits are on paper with the first loaded up rounds ive dne for a .270win.

The first 3 shots were loaded at the Start of 43gr, accuracy wasn't there but as said above main aim was to make sure hits were on paper!

Box of rounds in different grain - NOTE** the marks on the primers? Whats this about?

44gr marked with the Blue texta, although the Box was turned upside down to fire the new group. 45gr hits in black square.

finally a close up of the Black box with all the 45gr x5 shot group. using 130gr Corelokts, 'partially fls' rem 9 1/2 primers. Win once fired brass running right at or close to 2.540

I actually met a guy today who has a Chrono..... so one day in due time.. il run em over it!!

Yep CBFMI! I think you are right!!

I rekon its more accurate than that too, but with the rest an with my habit that was the results :) Loading up some more shortly an hoping to get to test out on some Game this weekend!


Ideally how would you sight this load in?
i'm thinkin of around 1 inch high at 100m.

I'd just use the rule of 3,3,3 and 3.

Take most any cartridge at about 3000 fps, sight it in 3 inches high at 100 and hold dead on to 300 yards where it'll be about 3 inches low.
