I recently mounted a Williams Receiver Sight on one of my Winchesters and took it out to the range for a few minutes to get it dialed in. I was fortunate that it only took a few rounds to get it adjusted. I then shot three 5-shot groups of three different bullets without adjusting the sights to see how it would behave. For reference purposes, the loads were:

1. Bullet: 44 Caliber Saeco #433, 292 Grains (rich in linotype)
Powder: Acc. No. 9, 18.0 Grains
Primer: Federal 150
Case: Winchester

2. Bullet: 44 Caliber Lyman 429640 HP, 265 Grains
Powder: H110, 21.0 Grains
Primer: Winchester Large Pistol
Case: Winchester

3. Bullet: TLC-432-285-RF (Ranch Dog Custom), 265 Grains (rich in linotype)
Powder: H110, 21.0 Grains
Primer: Winchester Large Pistol
Case: Winchester.

I was shooting at 25 yards, and with the exception of one flyer got a nice tight group about 2 1/2 inches high. The 100 yard lanes were all filled so I didn't get a chance to see where it would print at that distance, but I'm happy. Lots of fun and smoke.

I certainly enjoy shooting the Lyman 429640HP. In both 21" TC barrel and in the .444 Marlin Winchester Timber rifle the bullet shoots very well. Its hard to beat Winchester 296 or Hodgdon 110 but Hodgdon Lil' Gun seems to come close. The Winchester primers make a good difference.
