I think the remaining may be the either the press or the lube or both as you guys suggested. They are the only variables left.
Finally an excuse to the old lady to buy that T7 ive always wanted!
Sighted,
OK, the variance more than .002" is sounding like equipment but it is still a huge improvement....Why don't you load up a few rounds at .002" and see if they are reliable.
As you increase the bump past .002" the divergence could be because your case lube is not working consistently. Or it could be the press. But, no need to throw the baby out with the bathwater just yet until you fire a few rounds and see if your gun reliably cycles. If it works on .002" that'll be the best of all solutions - then you can decide to upgrade on your own time and terms.
I also recommend holding off on your home-brew lube and going commercial. It's not a big cost. I use RCBS and a roller pad. I use One-shot spray for bulk handgun cases but it'll work on bottleneck rifle cases. I don't like spray getting inside case necks when accuracy counts so its a roller pad for me.

Home Lube - 99% Isopropyl alcohol, or the standard 88 or 91 Isopropyl you get at the grocery? Pure Lanolin or ???. Gotta be the 99%. Gotta be the Pure Lanolin. Gotta me warm-ish like 90* when you mix it. You have to shake it up before you use it.
Yes the Pure lanolin and 99% alcohol is pricey, but for 8oz of lanolin and 16oz of Alcohol, you will never have to buy lube mix again...ever. I am still on the same 10:1 10oz mix I made in 2009 and I have lubed well over 15k cases.
Clean your die, don't over lube your cases. 150-175 cases in a gallon ziploc bag and 10 spray pumps from a hair spray type bottle for the first time, 6 for the following, shake and roll the cases around, dump out on a cookie sheet and let sit for 15 mins, reuse the bag for the next batch. If you are using a large spray bottle like a bath and kitchen cleaner type, then 3-4 for the first, 1-2 for the following. The alcohol will loosen up the leftover lanolin in the bag.
I presume you are not trying to resize the same case over and over. One and done, they don't play nice when trying to move .001 each time.
Clean those 1.210~ cases of lube and see if they will chamber and the bolt will close on them. If it does, run it. I'll bet your next cases come in at 1.214ish.
Check your trim length also.

Catchy sig line here.

Direct die to press engagement or you have those quick change bushings in your press? Could be getting play in the bushings if you are using them...possibly.

As far as case lube,I have buddies who use one shot,imperial wax,home made lube and all other kind of stuff.I stick with the ol reliable 2 oz bottle of RCBS case lube and RCBS pad.onlything you need to know is not to overlube or you will get dents in cases when you resize.

I had the same problem with one of my Grendel barrels I had to back the die out and aim for .004" bump.
My BCA barrel is head spaced perfectly for factory ammo so I used two die sets, one for each rifle.
I was about to dump the oddball chambered barrel until I picked up a third Grendel barrel and it is head spaced nearly the same. The .004 bump for barrel #1 gives .003 bump for barrel #3.

That's all I use as well unless I am doing neck expanding and then I use the Hornady spray to make sure I get inside the necks too.

If you fire formed them to 1.211. Why can't you just push them back to 2.010-2.09 and call it good? Did I read it right that you had success with just this little bump?

Good point Klem on trying the 2 thou. I guess i was so fixated on getting 3-5 thou it just hadnt occurred to me.
It’ll be a couple weeks before i get to the range again but i’ll let you know how it goes.

I use the lube recipe and exact same alcohol/lube that the 6.5 Guys did an article on a few years ago.
So yeah %99 and also pure lanolin. And yeah one bottle of lanolin and two bottles alcohol will probably last years.
Im gonna try the 1.210 rounds soon as i get a chance.
Thanks

What you are probably seeing is variance with the press camimng not caming over as you adjust the die in and out. Either get a better press or get some redding competition shellholders. With the redding shell holders you can run max stroke on the press and adjust the bump by changing the shell holder. The shell holders are sized to bump in .002 increments.

As I mentioned in post #18. Cornbread is correct, when you have solid contact between the shell holder and the die, you will have the most consistent sizing possible. Eliminates all problems with "press slop".
