Loaded some 260 rem today

[6MMsteve]

it was hot but I loaded my new 260 build with some peterson brass, let's start from the begins it's a 260 rem 26in criterion barrel, with big bastard brake on a stock rem 700 headspaced tight on the go, with a Jewell trigger set at 7oz that's what it was from the maker. heavy palma 1n8 match chamber, loaded 44.5 grs re23 behind 142 smk with br2 primer, topped off with a Kahles 10x50moak krg stock leaded down in rear but I'm gonna maybe get the wt system for it, got 50 loaded will chime back in when I shoot some groups, starting at .010 off the lands. 1 test fire shot shoulders grew .002 close to what I was expecting, atlas bipod with arca rail mount for the krg, back to loading it was hot upstairs so I used my lee dipper 3.1 to charge cases lazy me but I may be onto something

Careful with using the dippers or a powder measure and RL23, it does not have uniform kernel size. Even trickling it can be finicky.

the good thing is it's slow burn powder only reason I done it this way, I'm shooting at 100 yds, it's not the ideal way to do it, and it's slow, cool down is next week

 

[Fast14riot]

I'm shooting 45.5gr RL23 under a 153.5 in my 260AI. Just got back from fine tuning seating depth. Its a great powder for the heavies in 260 and 260AI.

I shot mine today also, I'm using a bipod 1st time ever it's gonna take some gettin use to, but 1st 3 shots cut a hole then I was trying to figure out how to get back on target gonna get a squeeze bag, I kept trying to shoot like I was in a rest it don't work like that. The Big Bastard brake takes all recoil away it's like a 223 I love that part, it's gonna be a shooter no doubt

I tried the small primer in my 260AI and with good results.

I tried to get a 260ai from northland but it was a 26wk wait, I'm glad your having great results.. the 260AI I use to shoot on a kreg barrel I used srp it shot well too I still have quite a few lapua brass for it and some loaded, that's why I tried to get the 260ai plus I don't have to trim brass or worry bout it

 

[Bill Norris]

I definitely love the "no trim" aspect of the 260AI. I measure each time I reload but it just don't seem to grow.

I never trimmed my 260ai brass, I shot some cases maybe 8x never had an issue

 

[Bill Norris]

I have some brass that is at 8 firings now aa well.

that's a good article I think I read that bout 4 yrs ago and it prompted me to 260ai land, it's a great cartridge I think it's much easier to tune than a 65284

This was my seating depth testing yesterday with the 260AI and 153.5 Berger. The two groups on the bottom are fire forming with 130smk pulled bullets. Its a performer for sure.

I had ignition problems with my 260AI using small rifle primers in Minnesota when temps dropped below 20 degrees using 4831. Just sayin.

 

[Bill Norris]

I have not shot any of my small rifle primer brass in the winter time but it may be O K as we don't hardly ever get down below 20 degrees here.

Winter temps here are in the high 50s low 60s. I don't worry about cold. We might get 3-4 nights in a row with high 20's as the low and a freeze warning gets issued.

Small primer and big charges in cold temps normally don't mix well.

I 'm gettin ready to make some srp 260 brass will be using rem 7 1/2 primers, with n160
