260-h4350-143eldx

So I ran this load over the magnetospeed this weekend.... 45.6gr H4350 under a 143 ELDX in virgin rem brass with CCI BR2. I was getting 2850fps with es 9 and sd 4. This all out of a 22" barrel with SiCo Omega supp. Does anyone else run a 260 at this level? Am I overdoing it? I wasn't getting any hard lift or flattened primers, no real evidence of over pressure. I'd like to stick with the load because it gives me great downrange ballistics and .5MOA accuracy.

Magnetospeed sporter tells me I am 2890-2898 over 10 rounds with h4831 sc and a 142 smk out of a 28" barrel. My rifle is long throated (.210") and I am at 46g of powder. Cci br-2, once fired lapua brass, bartlein barrel, rem 700 action. Book lists this as a compressed load but I do not feel any crunch when seating bullets and can hear powder moving when I shake a loaded cartridge. Shoots lights out as long as I do my part. I have only had it about a month but I am loving me some .260.

I was running 46gr H4831sc with the ELDX, and was getting 2700 on the nose. I went to H4350 to try and pick up some fps with the shorter barrel. I think some of the speed may be thanks to the suppressor, but haven't tested that yet. There was zero POI shift from the H4831 @2700 to the H4350 @2850, weird.
