There have been several discussions here on THR about the T/C Encore. Some people hate them some love them. I myself love my rifle and have 9 barrels for it.

8 of the 9 barrels have always preformed very very well. The 9th being my 28" pro-hunter in .270win has been difficult. I have tried hand loading I have tried several brands of factory. Always having basically the same result. Best groups of around 1 1/4 average close to 1 5/8-1 3/4"

I have kinda given up and decided heck its just a hunting gun why do I care about MOA or sub-moa results. The desicion was made to just go with a premium bullet from a respect manufacture and go with it. I purchased three boxes of the Hornady custom line ammo in 130 grain SST.

We were working at the range today building a new pistol berm. Three of us stacked railroad ties 36 feet long and 7' tall to be backed with dirt. by the time we were done all were tired. Yet here I am at the range and wanted to sight in with my choosen rounds. I fired 8 shots and was satisfied with my sights and decided to shoot three 4 round groups. The wind was blowing at 15-20 mph at my 7 o'clock and gusting up to 25 mph. temp 63 degrees. For a really basic setup I think it did real well.

The first group was 1 1/2" only do to verticle stringing no flyers. So that was me being tired and still probably breathing heavy. The second four shot group was right at 7/8" and the third and final pictured below. a nickle will cover all 4 rounds. Granted this proves little and someone will say it doesn't matter unless you shoot 10 round groups.

I am impressed with the ammo and this is the best this barrel has ever shot. I can't do this well with handloads. So I just ordered 4 more boxes of the factory.

this is definitely interesting. Just curious but how extensive were your load developments thus far with the .270 barrel

I have a picky .270 too. It is a great feeling when you finally get to see tiny groups like that.

I own two other .270 winchesters and they both shoot pretty well with handloads. Not sure why this particular barrel is so picky. My other 8 encore barrels seem to shoot spitballs reasonably well for a hunting rifle.

As to the question above on how in-depth I have gone in reloading for this particular rifle.

I have tried the following bullets

130 grain Hornady SST, 130 grain Hornady interbond, 140 grain Accubond, 130 grain soft points I think they were Sierra. 130 grain Barnes TSX, 130 grain Nosler combined technology.

Always used Hornady brass
always used Winchester large rifle primers

Powders RL-22, RL-19, H-4831

Full length resized and fire formed neck sized only.

Usually start just below mid-line on velocity/pressure range

I make 7-8 test loads. Five rounds per load going up the scale by .3 grains each time.

I run each test load with a clean barrel. Cleaned between each load of 5 shots. I fire one fowling shot with just cheap winchester power point. Then the five shells for the load. Time between shots is typically one minute or close to it. I weigh each and every bullet, and powder charge. Hell I have even weighed each case for consistancy at times.

If anyone has any suggestions beyond what I have tried please let me know. I like rolling my own but I am out of ideas.

Maybe the barrel likes to be shot dirty? I have several rifles (including 1 encore barrel) that perform better when the barrel has 15-20 rounds through it without cleaning.

Another thing it could be is the barrel itself. Could be the chamber was just a tiny little fraction off. I have several rifles that are kind of picky and one that will ONLY shoot one bullet, one powder, one primer, and even just one case combination. I have noticed that most all of my TC barrels (centerfire) seem to like Hornady brass the best. Could very well be the thickness of the brass. They seem to like Lapua at a very close second and Federal a very close third. Another thing it could be is your lockup with that one particular barrel. If in fact you are getting vertical stringing with all your other loads, it is more than likely that. Could be the pressure of the Hornady round that you found seals it up just right for a good shooter. Barrels can be a very funny thing and can make you want to pull your hair out at times.

I am going to get out in the next couple weeks and try this load at 200 and 300 yards. I would love to see this round hold up at these distances. If so might not be worth loading for anymore.

On a side not during reloading I have tried seating the bullets at .012 and .015 off the lands as well as seating to manual specs. We have taken a couple deer with this rifle and barrel. Its a hunting rifle so 1 1/2" at 100 and roughly 2 1/4" at 200 is plenty accurate for whitetail.

This is the second group fired for the day. 4 shots in the group; there is a fifth hole but that was from sighting in. I apologize for my dirty hands:)
