I replaced the front mounting screw on my lott with a new one and decided to tighten it with greater torque to see if it would make any difference.I received a SS screw instead of the normal blued,used some red loctite and started tightening it to 65 lbs-the setting I usually use.I then got out my Brownells screw driver and put a huge monkey wrench to the tightening nut.I then gave the screw an extra half turn,where it came to a stop.After cycling the bolt action,I felt a smoothness that I never felt before.The bolt would suprisingly work so much better at this torque.It would be interesting to see if it shot any different,I thought.With the new torque,the rifles POI was higher by 8 inches.The rifle would also shoot lower when I shot it offhand, compared to when I shot it off the bench(what it really should do),instead of higher.It shot very close to the point it shot off the bench.Accuracy improved and flyers where very few.Solids and softs shot to the same spot.I struck gold![URL= ]100yds off the bench/5 shot group + 1 fouler[/URL] [URL= ]100yds offhand[/URL] Five shot group includes two Woodleigh 550 FMJ's and 3 Woodleigh 500gr PPSP. | ||

Please note, not just an ordinary monkey wrench, but a huge monkey wrench no less!! Kind of reminds me of the old shade tree mechanic motto, "get a bigger hammer and we'll beat her 'till it works." I am absolutely sure that Ruger Firearms would like to be made aware of this method of improving the performance of their rifle. Holy Crap Batman!! | |||

So let me make sure I got this.... red loctite on an action mounting screw? red? really? And torque the screw past the yield point with a large monkey wrench? And it now works beautifully? Wow. | |||

65 FOOT POUNDS on a 6 MM / 1/4" bolt? STRAIGHT SLOT screw? I think you mean INCH pounds, don't you, flinchie? a SCREECHING stop, as it SHEARED OFF if you put 65+ft-lbs on a 1/4" screw its because you hands are numb from the "beestings of the bolt shearing

The key to shooting a Ruger .458 Lott is to be smarter than the equipment, in this case that might be a fairly tall order. | |||

I don't mean to offend if this was in fact a serious post, but this sounds like a spoof. If the torque has that much effect on the bolt travel and accuracy, it is a bedding issue. A properly bedded rifle doesn't act this way. PA Bear Hunter, NRA Benefactor | |||

Airgun, its a spoof .. georgie knows what he's doing, and likes yanking my chain.. i think it takes him days to dream up the dumbest possible combinations of things to say... like using 1 ring on a 458 winmag "jedi shooting" .. just focusing on the target in general, but not aiming wearing a skidoo helmut to shoot beating bullets, from his knees, with a wooden maul and lots of other things he's gone back and edited out opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

The fact that it's a Ruger magnum and a lott and has a special,large recoil or mounting screw,changes the rules. | |||

I don't know whether to leave this thread here (where it will devolve into yet another waste of electrons), move it to 'Gunsmithing' as a shining example of what NOT to do, or move it to Humor. What say you? George | |||

Tighten every screw until you feel it 'relax' then give it another 1/2 turn. Hunting is getting as close as you can, shooting is getting as far away as possible. | |||

I wanted to add an update to my original post.I was out at the range today to see if anything changed.It seems that the POI dropped a bit and settled a little lower-closer to the POI I had before adjusting the torque on the mounting screw.After firing the rifle offhand,I found that it still groups above the POI I get off the bench-the way it did before and in the same way my 308 does.So,the POI when shooting offhand is always higher than what is is when shooting off the bench and nothing has changed.The bolt does cycle smoother,however.The three shot,offhand group above was probably shot after the rifle settled to its new torque causing it to strike lower than the 5 shot group fired off the bench.I did some chrono work too,and got 2098 fps with 550 gr molly coated, woodleigh RNSP and 76.5grs of H4895 and 2139 fps with 77grs. | |||

Here is a 100yd,offhand group that I shot yesterday.The rifle needs a slightly higher front sight in order to bring the group down a couple of inches and the windage adjusted to the right by the same amount.It seems that I can't do anything about those flyers.I believe that some rounds take such abuse in the magazine,from recoil,that their accuracy is effected.Some bullets tips are really bashed.IMO,rifle magazines in such powerfull chamberings,need to have as little as space as possible,to prevent rounds from getting a running start,before smashing into the front wall.I am really happy with the group.With some more practice,it should get smaller.Preparing a powerfull rifle like this,the right way,will not crack any stock,feed any time and any place,will not misfire,shoot tight groups and keep its POI forever!

You would raise the front site to lower impact,but, I suggest you leave the elevation alone. Call it zero for 150 yards. Fine. I agree, you might move the rear a smidge to the right. There has been some pretty good suggestions for various standing shooting rests. One was a ladder, and another was a surveying transit tripod or camera tripod. Its looking pretty good. Maybe try one of those rests and fine adjust the windage. Edit: Its not clear to me, is that two 4 shot groups with a sight adjustment before the shooting of the 2nd four? Anyway thats my assumption and its pretty darn close on the final 4 shots. Edit2: You mention red loktite? That is supposed to be perminant. I believe it can only be released with heat from a torch. Ok, third edit: I looked at your photo. that is Permatax not Loktite. Thats a crescent wrench not a pipe wrench. You just say these things to get a rise out of jeffe? lol | |||

Thanks for the correction,fourbore.I need a higher front sight to lower POI.The size of the group is not caused by unsteadiness,IMO.I can tell that the hold I have is strong enough so that my front bead is not moving.What causes a slight error IMO,is the diminishing daylight during the time I shoot and how light itself reflects from the target to my eye.There is also "warm-up" to take into consideration.A slight warm-up,usually 6 or so rounds,is required before the shots hit home.What you have in this target,are the first three shots hitting orange(where they should not),then four shots striking home(to the left) and a single(corrected)round striking home,in the orange.In answer to your question,to the best of my knowledge,that is loctite and that is a monkey wrench-at least that is what I learnt in school,although my brother calls it a Westcott??As far as loctite or Permatex,you need it to shoot well-no doubt about that! | |||
