I bought 200 Norma 6.5mm Creedmoor cases a month or two back - not cheap at £120 / 100 including the UK 20% VAT (sales tax). Actually, at that price, I intended to buy 100, and the dealer gave me two bags thinking they were 50-ct. They seemed a bit heavy, and by the time I got home, my wife says a panicked gunshop owner has been on the phone saying he'd given me 200 by mistake! Anyway, after weighing / measuring a sample of 25, I went and gave him another £120 rather than return them - they are that consistent. They're a bit heavier than Hornady and have 14-thou thick necks v 13-thou for the US brass. Weights are within 1.5gn, a very few examples per 100 aside, and most are within a 1gn range. Necks are very consistent, 90 odd % within 0.0140-0.0145" and consistent around the neck measuring at three points.
I've only just started using them for load development in a Savage 12 LRP, and kicked off with the old low-BC 140gn Nosler CC that groups well with H4350, not quite so well with the new IMR-4451. However, the initial star was with Reload Swiss RS62. This is from the same manufacturer (Nitrochemie) as Alliant Re17, but without the added nitroglycerin treatment - ie a single-based 4350 speed powder. It is longer-grained too. Three round groups found a promising node at a modest 2,725 fps in the 26-inch barrel factory Savage and I was persuaded to use it in the 'Factory' class of our first UK Bench Rest Association 1,000 yard league round at Diggle in Northern England last Sunday despite limited load development and a rough new Savage barrel with less than 150 rounds down it. This is going to be disastrous I thought on Sunday morning wishing I'd taken my Stolle 6.5-284 Light Gun instead and the sighting-fouling rounds predicted a poor performance with terrible (like REALLY TERRIBLE) elevations - 30-inch groups here I come I thought. However, the barrel seemed to settle down as it fouled and the first three 5-round groups were all lateral with wind changes. Group 4 saw the wind drop, but an elevation based spread from mirage. The 4 x 5-round group 'agg' was just over 10-inches and the smallest group was 180mm (7.08"), so I was really pleased and not a little surprised. I was 5th overall in a field of 31 and 2nd in class. The Savage is a slow shooter as it's a magazine rifle and throwing a round into the port doesn't work - you have to 'fiddle' it part-way into the chamber with the finger tip or the round hangs up.
That was batched and prepped Norma cases (neck-turned to 0.014" as a light 'clean-up'), flash-holes uniformed, neck-sized in a Wilson arbour die and then expanded with a Sinclair E26 mandrel, CCI-BR2 primer, 140gn Nosler CC BTO-batched, trimmed and pointed at 20 thou' 'out' and 42.2gn RS62.
I've not done a water capacity check yet to see how the internal capacity compares to the Hornady brass. We'll have to see how robust the cases are too, although I don't intend to push them hard. For hot loads, I'll re-form Lapua 308 'Palma' small primer cases. Next on the agenda is 123gn bullets and one of the higher-BC 140s.
