Sorry it's taken a while. Checked my notes and I'm running 43gr which is pretty much a starting load. Haven't chronoed this load but estimating 2700fps. Not fast but I don't care. The bullet has enough accuracy and BC to make well placed shots.
Ok in my 260 I can't get enough H4831SC in a case to get pressure even with a 147g pill best I could get was just under 2710fps in a 24" barrel now with H4350 with a 147g pill 2850fps was easy with a cci 200 primer and still had radiest edges so I figure yeah you should get pretty close with a good load in a 20" tube .So you are saying that 2648 fps with a 139 grain bullet out of a 20" barrel is too slow and that I will get another 150fps if I use H4350 without pressuring out? Really?
Yeah, I don't think so.

So yeah I'm saying 2648 foe a 139g pill is creedmoor slow or slower .
I have a tikka forest 260 remington that I loaded some berger 130 vld hunting bullets for. Berger says with varget 33.5 to 37 grains max getting 2481 to 2703 fps. I got with 36.6 a speed of 2593 , i know their chart says they use 24 inch barrel and I have a 20 inch. My question is can I increase my speed safely , not much on pushing the limits but i see speeds of 2700 on this site can iI get there with shorter barrel . Second I noticed in write ups it says 300 plus yards for berger 130 vlds ,I get all my deer here 100 or less. will it not open right ?
Well I think any case lapua or not that will take 9 loads and neck size with very little resistance on a bolt is not a over pressure load .If you are pushing a 147 grain bullet at 2850 out of a standard .260 Rem 24" barrel, you are significantly overpressure, regardless of what your primers look like. Physics is physics.
Additionally, the 6.5 Creedmoor is essentially the same ballistically as the .260 Rem, so I am not sure I am getting your comment that it is "Creedmoor slow or slower". The .260 only holds about 2.5% more powder than a Creedmoor, but is a 60K cartridge, while the Creedmoor is a 62K cartridge.
At the end of the day, you do you. I will continue to chase accuracy over velocity and stay within sane pressures.
With regards to speed, I'd say that you should be able to get more than that out of a 20" barrel, but I'm not sure if you can do it with that powder or not.I have a tikka forest 260 remington that I loaded some berger 130 vld hunting bullets for.
