I shoot berger 155.5 fullbore bullets in my .308 Palma rifle. Depending on the temperature, the calculator shows around 1.44. They shoot great at 1000 yards with high x counts even with 4000+ rounds down the barrel. I would expect you will be fine, but the only way to know for sure is to shoot...
I shoot my 30" barreled Palma rifle with 155.5 Bergers at 3050 fps or so. Small primer brass handles it fine. I know guys using coated bullets at 3150. Still not 300WM equivalents though.
If you ever want to turn your case necks, a FL die will size the neck all of the way to the shoulder before turning. Bushing dies do not typically do that.
Here in Arizona I used 10x on a tripod for 20 years before switching to 15s. Bought the 12x50ELs when they first came out and the 15s and then the 10s went down the road.
Still use 8x30s for elk in timber. Nothing beats the 12s in normal open country glassing in my opinion, and can be hand held...
I have 2 pre 64s in McMillan hunters edge stocks. A 30-06 with aluminum bottom metal, FWT barrel and 2.5x8 Leupold weighs 7 3/8 pounds and a 6.5-06 with steel bottom metal, a Rock No.2 and Mark 4 10x weighs 8.25 pounds. S&K rings on both.
My old Lyman M5 will easily read to a kernel of Varget or H4895 that I burn in my .308 Palma rifle for LR target shooting. Wouldn't fret over needing that weighing accuracy for sporters as neck tension is likely more important.
