Yes, if you're going to be out in the sunshine on day in the low 80's, it's VERY nice to have some shade. I KNOW if kept some of the "red" off my neck! Rickey, don't let me forget it again!
Anyway, on to the results... they were VERY, very surprising... nothing that I expected. The ammo, .45Colt cases ( a variety of manufacturers were represented... To have been more scientific, I should have segregated ammo by case mfg'r. All bullets were 200 grain RFN, .452. Powder (for the most part), was Clays, 5 grains... but that ammo can also held some loads with RedDot, but should have been an equivalent loading... This was the left over rifle ammo from my son's & I excursion a coupla weeks ago to the Texas State Wild Bunch Championship! In chronographing the rounds for match qualifying, they only took one round, and if it passed the minimum power factor (150), then they didn't test any more. With the 200 grain pills ammo only needs to be 750fps to make the 150 power factor. As you'll see, mine did this.

Thanks RKrodle for the SD formula. So if there's any problem there... blame Rickey... the Ave. Velocity is mine own fault.
What I found interesting was the apparent sameness of the data from one rifle to the next... except for that little 1894 Marlin Cowboy! Either it just didn't get ANY of the low-speed ammo, or it's a little tighter chamber than the others. None of the loads or rifles were shot for group or to adjust POA or POI. Most shot "high" above POA. What I observed of group sizes (50 yard targets), is that they were between 2-3 inches. And all but the 1894 Marlin had a flyer or two! Go figure! It also has a rather large round bead front sight, which just obscured the entire bull of its target. (All five rifles were shot at individual targets, all of the same pattern). (I'd post pictures of the targets... but before I thought to take one, we'd taped new targets over those to sight in the new .223. Different subject, and will get its own post)!
