I'm shooting a Sako 75 AV in 270 winchester. Currently I'm getting 3.5-4 inch groups at 100 yards. I'm shooting remington core-lokt 130 grains. I know its cheap but what else should I try, going heavier maybe 150 grains?

I had a Browning A-bolt at one time in .270----130 grainers----5 to 6in pattern

150 grainers---1 to 1.5 group

140 grainers---SAME HOLE!!

Amazing.

With my .270 I shoot winchester 130grain softpoints. It gets me .75" 5 shot groups, sporter barrel and everything. Give it a shot, what the heck.

the load and brand of loading will make a big difference... just wait until you start handloading!!! :what:

Those core lokt Remingtons are trash. Take a few out of a box and look at the tips. They are all a little different. That lead tip deforms badly. Get something in either a ballistic tip or bronze tip. If you are going to hunt with it don't go cheap. Premium rounds really do perform better. For target, the $27.99 I spend a box gets expensive quick. But it's only like two boxes a season. For what it's worth, I use Federal Premium with the Barnes Triple Shock X bullet in 130 grain. I get three bullets touching at 100 yards. This is with a Tikka T3, which is made by Sako, so I know your gun can do it too. And make sure you have optics that do that rifle justice. Personally I have a Zeiss ZM/Z on mine. ;)

I had a .270 that liked 150's much better than 130's.

I put a bushnell elite 4200 2.5x10.

It seems to have pretty good optics. I bought the firefly reticle. which works ok not a replacement for an illuminated one.

I'm surprised that a Sako would shoot that poorly with any commercial ammo. I have not used a 270 for a long time, but I have owned several (Winchesters, Remingtons, and one Howa.) They all shot very well with 130 gr bullets. I usually handloaded Sierras. Definitely try another type of ammo. Your Sako should do much better. Watch-Six

Try a different brand, your gun will find one it likes. Also, make sure your scope mounts are rock solid, that could be a factor. More likely it's the ammo. You're shooting from a solid benchrest, right? And, of course, let that barrel cool between shots if you are looking for tight groups. A hot sporter weight barrel will open up groups.

I've found that my Remington BDL .270 absolutely loves the Hornady Light Magnums in 140 gr. I can get .5 to .75 on a good day if I do my part. But it'll only do 1.5 - 2" at best with Remington 130gr corelokts. Once you find the ammo your gun likes, you'll know.

Thanks again for all the good information you all have provided. I was shooting off sand bags with a solid bench underneath.

Bayou Boy, I discovered years ago that as you shoot from a full magazine with lead-tipped bullets, the battering is progressively more with each round shot.

The thing is, it affects accuracy or group size very, very little.

I've done comparisons with single loading the cartridges, and it just doesn't really make any difference. Aw, maybe from 3/4" at 100 yards up to 7/8", but that's not enough to worry about. Just as easily could have been my shooting and not the bullet deformation...

Flattening of the nose is likely to affect the trajectory out beyond 300 or 400 yards, I'd guess, which would lead to vertical stringing--but that's beyond normal hunting distance.

My usual handload for the .270 was with the Remington 130-grain Bronze Point. I used surplus 4831 powder, just pouring until the case filled and then compressing the load. From the literature, that was around 45,000 psi or so; less than max. Quite accurate. Reasonable exit wounds on cross-body shots on Bambi.

Art, I'm not talking about the battering in the magazine. This is brand new bullets out of a Remington box. All of the tips are mushed differently. in my mind, I prefer shooting bullets that are exactly alike, every time. Looks like you do too with the bronze points. ;) I guess that I just realized that there are better bullet designs now than the old lead soft point. Better performance ( in the air and in the animal) are worth more to me than a few bucks at the store.

Hokay. What you're talking about might indicate an imbalance in the bullet. This might induce varying amounts of yaw and result in patterns, not groups. :)

I'm mostly a deer hunter, and the Rem BPs, Hornadys and Sierras have always worked well for me. That's what has kept me from bothering with premium bullets, not the cost of them. But I do avoid the cheap stuff.

I have a Ruger #1A in 270 and the 160 gr Nosler partition will out shoot the 130 and 150 gr bullets of any style. the 160's are good for less than an inch for 3 shots at 100 yards. the 160 is the only bullet I use
