    Here's hoping that Zeiss makes it good for you. Lots of time they will look at how old the scope is not so much how many rounds it has seen.

    I found that reloading worked out for the best with many .270 that I had and as like you, did not get satisfactory accuracy from factory loads. However that was many years ago when I was messing around with the .270s. I gave my last one to a daughter in law with the warning that it was a great shooter out to about 200 yards and she was tickled to get it. I think she has traded it in on a 6.5 Creedmor since and I agreed with her on that trade.

    Maybe I just had bad luck with .270s but I didn't find them to be an accurate caliber for me. Mine struggled to keep things under 2.5" at 100 yards. I stepped up to a 300 Win Mag and found much more accuracy.

    Good Luck on the scope side.....maybe look at a Vortex is Zeiss craps out for you.

    I have already submitted an application to Leupold for the LE/military discount program. I am looking at a VX5 2-10x42 if Zeiss doesn’t make right for me.

    I have 200 Federal brass in the tumbler right now. Too bad I don’t have an optic to use.

    I’m going to go ahead and load up a few starting loads.

    I’m bored.

    I’m headed to the range tomorrow. Since my 270 is sans optic at the moment I am working on a few test loads to try out in 30-30

    It’s a Marlin 336 with a Leupold fixed 2.5x scope. It’s a great little brush gun, but not really the setup to get MOA groups with on the range.

    But I think I can do better than the 3 moa groups it typically shoots with factory ammo.

    I have some Sierra 170g flat point bullets and I am loading up some test loads from the Lee manual with 4064, 4895, and BLC2.

    I plan to chrono and shoot a 5 shot group with each tomorrow. Hopefully one works out well. I have plenty of BLC2 and 4064. Be nice if one of those works out.

    Well that didn’t go well at all. It did not like my starting loads with any of the three powders I tested.

    5 shot groups that were all 4-5 moa. Very disappointing.

    Guess I need to find a different bullet.

    Zeiss has my scope back at the mothership. No word yet on what they are going to do to help me out.

    I have a few test loads ready with 130g and 140g projectiles and 4064 and 4831.

    Hopefully one of them shoots well. I’m looking for about 2700 FPS. I want them nice and soft shooting. I’m beginning this with the start loads from my Lee manual. I’m looking for accuracy, not interested in them being hot.

    You need to start thinking thinking in terms of BURN RATE. BLC2 and 4064 are medium burn rate powders better suited for the 308. The 30-30 has a smaller case relative to the bore size when compared to the .308. BLC2 might work OK but 4064 might not. Traditionally the 30-30 as been loaded with 3031. Look at a burn rate chart to see where these powder fall in order of burn rate.

    the Smaller the case capacity relative to the bore diameter, the faster the powder needs to be, and teh smaller the bore diameter relative to the case capacity, the slower the burn rate need to be The reason the 270 need slower burning powders than the 270 is that while the case capacity is the same for both cartridges, the bore diameter is smaller for the 270.

    That’s good info. My local shop should have a pound of 3031. It wouldn’t be a big deal to pick some up, but I was hoping to use that I’ve got.

    Zeiss contacted me by email today. They are willing to replace the scope free of charge. They offered to replace it with a 3-12x44mm scope that is a couple hundred dollars more MSRP than my original scope.

    Problem is it’s a 30mm tube and a larger objective. That’s means new mount and rings on my part. That’s a great deal if added expense. I have a Leupold one piece mounts and low mount rings now.

    I have responded and am negotiating to receive a comparable scope with a 1” tube.

    We will see what happens.

    So Zeiss USA is the biggest bunch of nations I have dealt with in a long time.

    They don’t make my Zeiss scope any longer so they offered to replace it with a newer comparable model.

    They asked what I wanted and I said I wanted a 1” tube, 3-9x, 40mm objective. Small compact hunting scope for killing deer inside 250 yards, but with good glass because the woods in my area are dark in the winter.

    They write me back and say they are going to replace it with a 4-12x 44mm objective scope with a 30mm tube. They stressed that they would not ship anything without my prior approval.

    I responded that I didn’t want to have to purchase new rings and asked if there any other options.

    Today a 4-16x giant 3 pound rifle scope with parallax adjustment, elevation turret, and 30mm tube arrived on my door step.

    A nice scope no doubt........for Lang range competition. Certainly an expensive scope. But not at all what I want for my needs.

    I’m debating selling it and buying a Leupold VX5 rather than deal with these goobers any more.

    Most 130 grain and 150 grain bullets are flat base bullets.

    Most 140 grain bullets are boat tail bullets and I get really good results with them.

    Favorite 270 Winchester powder for me is H4831sc.

    Some rifles like 130 grain bullets, but not 150 grain bullets, while some rifles like 150 grain bullets, but not 130 grain bullets.

    Most rifles shoot well with 140 grain bullets, but there may be some rare exceptions.

    IMR-4350 usually works well.

    Accurate 3100 has been discontinued, but was made at the same Canadian factory that makes the IMR powders and was similar to IMR-4831.

    H4831sc is still my favorite for 270 Winchester,

    I finally got my scope replacement mounted and made it to the range this afternoon.

    It was hot and humid as hell.

    I got some decent results, but nothing sub MOA. Plenty acceptable as a soft shooting hunting load.

    I also got a decent result with some cheap Speer Hotcore SP 130g rounds. I’m not a fan of ballistic tip hunting rounds. Those will be a great soft shooting hunting load for deer inside 100 yards. At 2500 FPS they had the recoil of a .243

    Very pleasant shooting.

    White tail buck won't know if bullet hits him at 2900 or 2850.

    Well exactly, and it isnt changing bullet drop over any reasonable hunting distance.

    Yes. 100 yards shooting off of sand bags from the bench.

    The gamekings are pretty decent shooting bullets. I would exoe t something close to 1.5moa or better in a decent rifle.
