At present, groups are nothing special to write about...using the 160gn Hornady RN Interlock, they're coming in at around 1", & 1 1/4" - 1 1/2" MOA with the first two loads I tested.
Good enough for me to take three feral billy goats at 75yds. They dropped like stones.

Next to try is find out whether backing off propellant charge gives an improvement with that bullet. I don't really want to adjust seating depth as the bullet is 'roll' crimped into the cannelure.

Also on the list is the 140gn Hornady SST. This round I know doesn't load or feed as smoothly from mag to chamber, but it's passable. I haven't actually fired any of these rounds yet as I was waiting for Lee to supply a custom made Factory Crimp Die...that's now arrived & I crimped the rounds yesterday.

Incidentally, the guys at Lee Inc. were very helpful and turned around the custom die within the eight weeks they quoted for supply. The only problem I had was mailing an inert round to them. Royal Mail wouldn't touch the item. Fortunately, A good friend in the USA was on vacation in the UK and carried the round in his hold baggage and mailed it when he got back to the USA.
Lee returned the inert round to me along with the new die.....and Royal Mail handled the return!!! funny that!

We shall see what happens! - Hopefully, next weekend.
Cheers, deeangeo
