My CZ 550 in .270 shoots best with 130rg Sierra ProHunter bullets over 54grains of IMR4831. I use winchester brass (match preped) and WLR primers

For mule deer and similiar sized game which bullet do you think is the best choice in this caliber for accuracy, terminal performance and sex appeal. And which primer, powder and brass do you use to push it out the tube.

I used 52.5grs IMR4350, Win primers, and brass with 150BT, very good accuracy @200yds. Jay

Mulies are a little heavier than our typical whitetail and I'm a big fan of heavy bullets. In my 7x57 I use 160 and 173 grain bullets and 150's in my 270 (although I don't hunt with it much anymore). My personal preference would be to stick with at least a 140 grain bullet in the 270.

308Sako,

The 130 grain bullet is the classic western deer load in the .270. I worked up a load for a friend using the 130 grain Swift A-Frame bullet and RL 22 in Federal cases with Winchester primers.

Your rifle will tell you whether it prefers 130's or 150's. The classic .270 load with 130's is 60 grains of H 4831.
The classic load for the 150's is 57-58 grains of H 4831. I favor WW brass and WLR primers, but that is personal preference. My .270 likes the 150's better, so I bought a couple hundred Nosler Partition cosmetic seconds for about $12.50 per 50 at the time. It tips deer and antelope over just fine as far as I'm inclined to shoot at them (200 meters).
If you are indecisive you can use 140's.

One of the cool things about the .270 win is that the bullets for the most part are driven at predictable velocity. The .270 weatherby and the newer 270wsm while both are good cartridges the bullets are designed for the standard .270. To me that means since the cartridge has been around so long , they shoul have it right by now.
I would play around with 130 grain bullets till I found 1 that shot well at the 3000 to 3100 fps. Using H4831 IMR 4350, RL 22 or H 414 in that order sould get you there.

Tough to pick a wrong buller for deer sized game in the .270. I really like the 140 Hornady btsp for deer, but just about any 130 & up will work. I'm using 150 Noslers this year, but my Muley hunt is comboed w/ black bear, so am erring on the side of caution. I tend to use H-4831SC these days in my .270. Some powders give a bit more velocity, but H-4831SC is near the top and is temp stable. IMR-4831 is also a favorite and produces excellent velocities. RL-22 gives great velocity, but I have had bad luck with lot-to-lot uniformity w/ RL22, so am close to giving up on it. Magpro looks to be very promising in the .270 and velocities over the chrony match the lofty published specs (3200+ fps w/ 130s), but I'm too happy w/ H-4831SC and it's predictable performance in the .270, so saved the magpro for my .270 WSM. I generally use Winchester cases, but Remington work equally as well. Rem cases are a bit softer & have a bit less capacity, so loads are generally a grain or two lighter than what you can fit in Win cases. I used to use CCI-250 primers, but have recently switched to FED 210M primers. No particular reason, nor have I noticed a diff yet.

Good Luck,

Lou

308:
I personally like 150 gr. bullets in my .270 Win. but then again, I use it for sheep & caribou, not deer. I had problems finding a consistantly accurate load using the "standard" .270 powders, ie the 4831's & 4350's. I've since gone to 56.0 grs. of Rldr-22. I'm getting consistant 1" or less groups and velocities at about 2880 fps as measured from the chrono. The std. deviations are in the single digits as well. Once you find the most accurate charge, start playing with seating depth, I suspect that will make a difference. I think that seating depth is second in importance only to using the correct powder and always measure cartridge length to the ogive & not the OAL.
Hope this helps some. Bear in Fairbanks

I agree with the idea that it really doesn't matter. The 270 will kill equally well with any good bullet between 130 and 150 grn. If you get into the ballistic stats past 500 yards then the 150 gets an edge but a really meaningless one for most of us.

150 grain Nosler Ballistic Tips over 58 grains of H4831SC would be a great round for the game mentioned.

The 150 Hdy. SPILs (over the same charge) are very accurate too. It really depends on how flat you want to shoot.

You might want to start at 56 grns H4831 and then work up.

Good Luck!

Gentlemen, Thanks so much for the experienced view. I have been loading with R22, and IMR 4831 and IMR 7828 which I had on hand. Trying all with the 130 and 140 grain weights. Generally good results, but there is so many bullets to choose from these days it's a wonder we ever get to shoot more than one caliber! The chrono really likes the R22 and so do the targets, though the IMR has given tighter groups the R22 has been more consistant in the SD's and roundness of the groups.. The Interbond has been a tricky devil to get accuracy from, but the speeds are mighty tempting. Since I am a Libra, and therefore pre-disposed to indecision... I'll be trying the Nosler Accubonds next as Nosler products haven't let me down yet. Thank you all nce again... it does help the thinking process!
