Guy I'm buying it from seems to have had some luck with it and I'm hoping to have some more tweaking and see if I can get it down to 1/4 MOA or better. He's got some things going with it that are at and below 1/2 MOA with AMAXs. He hasn't put Bergers through it yet. I'm hoping to get good results with the 140s.

Re: 260 Rem Load Recipeies?

fellas thanks for the info and this is all realy interesting reading. as for the 2.875 seating depth for the 260 i did that for only the first 20 break in rounds for my new krieger barrel. throat polishing was the only intended intent there and kept the load low and wasn't too worried about speed or accuracy, surprisingly i did get both though even with the seating depth. as you can see from the picks it did really well and i already have another batch of test loads. my buddy's 260 is one holing groups at 100 yds and he is shooting the same caliber. just need to polish up the load and get dialed in. i am starting off with the lapua 123s and then going to work with the 140 amax. i might trythe smk and berger just for kicks. thanks fellas for the info.

2.875" is different than the originally stated 2.785". Maybe the first was a typo?

Re: 260 Rem Load Recipeies?

jtkratzer, sorry man i just had refractive eye surgery monday and it has been a little hard to see the computer screen 2.875 was a typo and i shot the first 20 rounds at 2.785 just to polish the throat. they were simply break in loads and krieger barrels come through with pretty tight tolerances so i figured backing the round out with a little jump would assist with not jamming the bullet. i have found that 2.795 is probably the optimal seating depth with just a smidge of jump because it is so tight. i loaded up another batch of test loads based on my previous data and i have not jumped those bullets yet but set them at an even 2.800 which is factory COL. I got some bergers as well and most guys know that those like to be slightly jammed so i am going to try that as well once they come in. thanks for the info. take care.

Lasik or PRK? I'm guessing Lasik if you're reading already. I had PRK done about 16 months ago and it was one of the best decisions of my life. I'm 20/15 in each eye and about 20/10 with both eyes.

Have you measured your chamber/throat with an OAL gauge? You may run into your magazine being too short to feed rounds loaded to touch the lands. I found a load that didn't mind the longer jump, but it's not ideal for Bergers, which I haven't tried in that rifle.

Re: 260 Rem Load Recipeies?

Hello everyone,
Hope you dont mind me throwing my question in here! New to all of this, site, LR shooting and reloading. Recently purchased my 260, the guy I bought from gave me a little load info. He said "its throated a little long" he was running 142SMKs at about 2.95" COAL using H4350. I was planning on starting with Varget, got the reloading data through Hodgdon and my manuals for starting load. Question is does that change when the COAL changes? Hope I'm not asking a Mr Obvious question but I figure when it comes to reloading the ole "only dumb question is one not asked" applies!
Thanks for any help
Scott

Are you using the same bullet he was for the load data? If so, first off - why change the load or was it not good enough? If you are using the same bullet, that length doesn't need to change unless you want to work on the seating depth for better accuracy?

If you have an OAL gauge and bullet comparator, you can measure the length from the base of the case to where the bullet ogive touches the lands.

If you haven't read The ABCs of Reloading, start there and read through your reloading manual. There are loads of people who can help you out here.
