Range Report 260, 123gr velocitys

[krw]

I am currently having a 260 built. I want to shoot the 120-123gr class bullets. It will have a 22", 1-8.5 twist, 4-groove Kreiger bbl. Can I expect to get 2900fps? As this will be a hunting rifle, rifle will never see 2k rounds so bbl life is not an issue. Thanks krw

Should be easily obtainable.

2,900 should be doable with 123gr Scenars and Hodgdon H4350.

I am getting 3,175fps out of my 26" 6.5-08AI (260AI). With 120gr Barnes TSX bullets I am getting 3,200fps with some pressure signs.

It shouldn't be a problem. I was getting 2950 with the 123's out of my 26" 6.5x47.

krw, I shoot 123 scenars out of my Creedmoor.

3020fps
44grs H4350
26 Rock 8.5

You should be able to get 2900fps out of your 260.

Work up to it!

I was getting 2925 with the 123's from a facotry barreled gas gun that was only capable of throwing 140's at 2700fps.

You should be just fine.

260, 26" schillen, r-19 41gr, 123amax = 3130fps

Re: 260, 123gr velocitys

2905fps @10ft 43.7gr H4350 123 amax' 24" dpms 1:8.5

R17 can add around 50fps, but the H4350 was more consistent for me.

3020fps- over chrono @ 10 ft H4350 45.7 gr.- 22.5" bartlein with b/o brake.
nosler 7-08 brass
Wolf LR primer
I would think that 3000fps is attainable, but work up to this load.
