Anybody need a new electric lawn mower (corded or battery)? I've got a $150 credit at Home Depot towards the purchase of a new electric mower. It's good at any of 9 select Home Depots around the Valley. Will "sell" it for $75 so you save $75 on a mower purchase. I'd prefer to meet at one in N. Phoenix or Scottsdale to apply it toward your purchase. Thanks, Bruce

Are you looking for gas or electric?

+1

Are you sure about that? Lyman made the Cutts with interchangeable tubes too. How do we tell the difference from the picture?

Orig plastic grips too?

Yeah, very nice! If the serial number is less than 2,600,000 it's a "pre-64" and then they skipped 100,000 and restarted with 2,700,000 when they changed the components.

Marlin Glenfield model 60 semi-auto .22 LR. $100 FTF in N. Phx. Stock has light scratches as shown in pic, bluing nice, no rear sight ramp. Must be an Arizona resident and not a prohibited purchaser. Sorry, no trades

Have a Ruger 77 in 7 mm Remington Magnum. It's the center safety with red pad vintage. Serial number 77-23xxx dates it to about 1971 (no warning BS on the barrel). Gun has been hunted so shows some blue wear and a few scratches in the walnut stock (original finish), but overall in very nice shape for it's vintage. I've owned it for many years and never shot it so I do not know the round count, but the rifling looks perfect. 24" barrel. Checkering is sharp. Buyer can have choice of regular or high Ruger rings. $375 . FTF around Shea and the 51 in Phx. Must be an Arizona resident and not a prohibited purchaser. Sorry, no trades.

I'd like the old Kollmorgan scope and if I read it correctly, one of the bases is for a Springfield. I could use that also. I'm in Flagstaff, but will be down in the Valley the middle of next week.

I have a pair of Leica 12x50BA with all original accessories, box, paperwork. Original owner. $950. Glass and exterior like new. Replaced a few years ago with Leica 15x56. Just FYI, I'm a big Leica fan with 8x32s and 8x42s. Nothing against Swaro's, but I prefer Leica's. I'm in Flagstaff and will be in Phoenix in a few weeks.

Thanks dse for your insight with respect to twist. That makes sense to me if the custom rifle has a faster twist that is not too fast, which I know can harm accuracy. I'll have to study the physics of the spin as it slows down. Since it takes more twist to stabilize a bullet at higher velocity, it would seem fine that the spinning slows as the bullet's velocity slows, but they may not be proportionate. " I have a old almost factory hunting rifle that will not shoot better than 3/4 moa at 100 yds, but I can shoot 1/2 moa at 800 yds all day long" Now that is fascinating. Intuitively that would seem to defy geometry. Once the angle between two lines (bullet paths of two shots) is established once the bullets are in flight, for that angle to change and always get smaller is hard for me to understand. MOA is "minutes of angle" and for the angle between the lines to always bend together with increasing distance is hard to explain.

I need an education please. I'm 70 years old and been shooting and handloading since I was 15. My academic background is mathematics (geometry). I'm admittedly not a long range shooter and have owned many rifles and only one custom which was willed to me by a good buddy that passed so it was not built for me. Some on this thread have implied that a factory rifle may shoot fine at 200 yards but not at 600 or 800, whereas a custom rifle will hold groups out to those distances. Can someone please explain the science behind such? If I have a factory rifle that shoots .5moa (or .2 or .3 whatever) at 200 with load X and a custom rifle that shoots .5moa (or .2 or .3 or whatever) at 200 with load X, why would the custom do better at 600? In my mind, the trajectory of each projectile is established by 200 yards and beyond that the wind, etc will affect both the same way. The bullet does not know what rifle fired it and the path is established. The bullet was clearly well stabilized by the twist of each rifle or it would not shoot at 200 so twist is not a factor. I'm serious and hope to learn why between 200 and 600 or 800 etc. the path of the bullet would differ between a cheap rifle and an expensive rifle that both shoot the same size groups at 200. Thanks, Bruce

"Inexpensive" will be the tough part for a cartridge like the 300 H&H. Good luck with your search. The old M70s in such calibers are neat guns.

Perhaps given the tone of this thread, he is justified in not feeling like he has to explain anything to us. Someone earlier in the thread commented on the decline of comity on the site. Perhaps we all should take this opportunity to reflect on the way each of us conduct ourselves. I will. Bruce
