What rifle are you using? Is it 50 caliber?

That bullet, unlike it's sister (Hornady SST) should load relatively easy in 50 cal rifles. The only time I experienced tough loading with T/C sabot/bullets was when I experimented using Ballistol & Lehigh Valley lube as swabbing agents between shots. The bore, when warmed, would get sticky/gummy.. making it difficult to load bullets. I've since went back to alky/windex spray which keeps the bore smooth & non-tacky.
