Thanks Jim C. That's the kind of information I am looking for.

John I don't have a customer lined up yet, so can't ask. If I knew the rifle was going to be used for deer sized game only I might go with the `150 grain bullets. But I live in Wyoming and the "common game" here is elk, so I want to zero for a load that is good form them. I do expect to sell the SMLE "Speed" to someone in Wyoming just because there are many men and a few women here that are "rifle lovers" and is seems that about everyone in Wyoming hunts. I don't have to mess around with any federal regulation either, if I sell it to a Wyomingite.
Not that I would not sell to someone somewhere else in the USA, but I won't advertise it outside Wyoming at first. If Ic an't find someone in Wyoming that wants it in the first 3 months or so, I may "put the word out" in the rest of the USA.

If anyone here on this site is interested, please contact me before I finish the zeroing, if you have other preferences. I can do it any way I am asked to, but I am taking a guess as to what would be best.

I think that because the 3 balde rear sight will have zeros at 100, 200 and 300 yards, there should not be any disadvantage for the hunter of smaller deer. You simply flip up the sight that is closest to the range and hold dead on. An "elk load" kills deer ok. So other then a heavier kick, I see no down side to using a 170 to 180 grain load.

Your thought?
