Reloading Data

jgchevyman · Posted: Fri Sep 11, 2009 9:54 pm Post subject: Reloading Data

I am looking for some reloading data for a 270 WIN. I have been searching for as much load data as I can find for this caliber for a while. I am new to reloading and just trying to get some stuff together. I have been online on the powder sites and have there data, but I was wondering if anyone has data that they use that works well for them.

Welcome. As you get into reloading you will find that each gun likes it's own recipe. The best thing to do is find a bullet that you like and find one of the recommended powders and start working up a load. Always start at the low end and work upward in .5 grain increments. I usually load up three rounds of each of the .5 gr increments. When you shoot you will be able to see which load gives the tightest group. After you find your group then you can start adjusting seating dept. For my .270 I like 130gr Sierra boat tails with IMR 4831 or IMR 4350. I have recently switched to Hornady 130gr SST's for the simple fact that the Sierra's went up by $10.00 a box. The only reason I use IMR powders is they are what my father and grandfather used so all the secret family recipe's have been worked up years ago. There are a lot of places to get load data but I really like having a couple of big manuals plus the "One Book / One Caliber" manuals all the data is in one book. In this day and age Powder and bullet availability in you area could be a consideration.

Thanks for the welcome wiersy111..... I have been thinking about reloading for a couple years now, as it worked out my father-in-law had a RCBS JR3 press he does not use anymore and he gave me the stuff he had. I am really getting excited about reloading my own ammo, I have been looking and trying to decide on what bullet gr, powder etc. to start with. I got the newest addition Lyman reloading manual and have read it a couple times already. I think I am going to start with a 150 gr bullet just cause thats what I normally shoot. I really think this will be my new favorite hobby while saving money in the meantime, I realize this will be a learning process and will appreciate any tips anyone is willing to share.

THANKS IN ADVANCE

Starting with a bullet weight you already know how performs in you gun is a step in the right direction. I find reloading very relaxing so I spend a lot of time at the bench. And in turn spending more time on the bench gives more ammo to take out and test so more shooting time which means more reloading time.It's just a terrible viscous cycle.....I love it.

Welcome to Reloading............... I don't have a 270 ww but I do reload 270 for my brother-in-law. For deer I load 130 gr Hornady with a good dose of ww 760 powder and for Elk I load 140 gr nosler with another good dose of ww 760 powder. For details email me at m1895ss @ yahoo.ca

i like the 150's and 160's with imr7828 but everyone I load for like the 130's w rl22.

The link below is a good source for reloading data for the .270 Winchester. I prefer 130 grain bullets and IMR4350 powder. Hope this helps. All the best...

I bought my Tikka .270 Win in December and started reloading. One of the most significant factors that has affected my load accuracy has been the brass. I started with a Winchester brass that I had bought new and has some Remington brass left over from the box of shells I used to break in the barrel. I was getting frustrated with my groups not being consistent then finally realized it was the brass (newbie mistake). When I separated the brass, the groups started making sense. I tried all the powders and brass combinations. I found out that my Tikka likes Remington brass for whatever reason (1/2 MOA compared to 1.5 MOA). I found the same issue with brass on my .308. My .270 also likes the IMR 4350 powder the best.

I now work up a load by loading up 3 shots each at 1 grain increments skipping the min and max load. Shoot those in groups then determine the sweet spot and load up 5 shots each (15 total) in .5 grain increments; 5 below, 5 on the sweet spot, and 5 above. It takes me a lot less time and fewer rounds to find the best combination for my rifle. I only need 2 shots to tell if a load is bad. You need multiple groups to know if its a consistent performing load.

Also, Take a look at the Barnes bullets. They have been doing well for me and I'm achieving higher velocities with hardly any fouling. Their 110gr TTSX is great on deer and shoots very flat with a muzzle velocity around 3400 fps.

i loaded some 130 grain sierra sp bt for my father-in'law and he wanted to start out with 44 grain of imr4064 .took it to the range and at 100 yd and 3 shots later ,he could cover all three bullet holes with a nickle..said he did'nt want to change a thing. load them all the same way he say's..... hahaha

I load 130 gn Sierra SPBT with 45.5 gn IMR 3031 and get sub 1/2" groups at 100 yards with my 270 WIN Tikka. Also, use same bullet with 56.5 gn of IMR 4831 and get sub 1" groups. Cool

Chevyman:

The .270 Winchester is one of the easiest calibers to find good loading data for. It has been around almost 100 years. It is also very accurate and shootable with almost any bullet weight, and will do for most any beast in the continental U.S. with the exception of the great bears, and an old time Alaskan game warden used it and 170 gr. bullets to take a potful of brown bears, soooo..you take your choice, there.

Find another reloading manual or two, read them, then choose a load (not max., at first), and have at itl I have had good experience with 130 gr. bullets, but the 140 gr. are no slouches, either.

IMR 4350 or 4831 gave me the best accuracy/velocity in my .270, but YMMV.

Good luck, and have fun! Smile

+1 on that.

You do need to get a manual or two. At least get the powder manufacturers freebees.

A Lyman or Hodgdon loading manual would be a great as set to any new reloader. Actually, they are all quite good but those two may be the best choices for a newbie.
