Thanks Josh!! It gives us newbies with the SML an idea what is possible, especially with the high BC bullets and time spent on the bench. No wind makes good groups but breezy days can teach you a whole lot.

josh-great shooting as always! glad you are learning the wind so to speak. I have a 435yd range next to the house that will take sub-moa shooters to 1 -2+ moa if they are not very careful. I still take it on for the learning experience's//the only way to get better in that dept is shoot in all kinds of winds & terrain's with a well grouping gun.
well done!

Thanks guys!
coyotemaster, I've learned on my range, with the prevailing southerly wind in the summer and early fall, I'm getting a lot of vertical dispersion since the last 250 yards of my range ramps up about 35 feet or so.
It's causing the wind to compress and push the bullets upward greatly. Since the lay of the land is re-directing the Southerly wind in a steep upward direction as is follows the hill upward.
So I'm trying to hold out for NW or Westerly wind to shoot with when gauging wind from now on.

500 yards Savage T/A .451 327 MH ~3040 fps( guessing, didn't use chrony) IMR4831 CCI 209M primer .040" bushing with 15/64" PFC Shot two 3 shots groups tonight. The previous group from the other night is marked "1" Second group "2" Third group "3" Both groups 1 & 2 I was aiming at the center bullseye. So I'm shooting to the right a little bit. Group 1: all 3 shots there was little or no wind. Group 2: the first two shots there was little or no wind, and on the third shot the wind picked up a little. I thought I timed it right. Wrong. So that bullet is marked 2-W Group 3: wind E-SE ~ 0-5 mph. This group I held on the green ring on the right side. The first two shots in Group 3 I timed pretty good, the third shot I did not flinch. Left to right it's pretty good, but it's very low. I'm guessing the barrel was just a little to warm to shoot, OK it was very warm. So I'm guessing that's why it's low. I don't know. 7 out of 9 bullets in 3 1/2" @ 500 yards. 1 bullet pushed to the left by the wind, my fault for bad timing. 1 bullet low, hot barrel?   |

Y'all amaze me, I don't think I could hit a Walmart super center from 500 yards.

Nice shooting! You might be hitting that dead tree as the bullet is coming down into the target. I would cut it down and get a clear flight path. That is longer than I would ever think of shooting or even try.

Savage T/A .451 29 1/4" in front of the lug. 327 MH 3055 fps over Magnetospeed CCI-M 209 primer Swinglock full form die Made a 1 click adjustment to the left from previous target Wind: SE ~ 3-5 mph, quartering from my right rear, wind pushes bullet at various points from 0-500 yards A big thanks to airborneike and 7mmfreak, on schooling me with the wind I was holding on the bullseye Wind was pushing bullet from right to left. Shots 1 & 2 are right next to each other, with the flags moving exactly the same both shots. Shot 3 is to the lower left, the wind was picking and dying, picking up and dying...3rd shot timing not the greatest. Every group I shoot, seems the third shot is a little low. I'm trying to figure out barrel heating and cooling by delaying the third shot a little to get it up in the first two shots. The vertical spread is ~ 1 1/4" 500 yards  |

Earnhardt- you are the long range standard to be measured up to! what powder,charge & bushing,fpc? if you don't mind........
seems the 327mh to be in the wind deflection chart around .590 bc in the real world according to your approx. results... I am finding the approx. same with my new gun @ 2730fp[s also again & again.
nice shooting! ps..327mh = *windbucker king* in .45mz

Thanks guys!
deadeye, like I said before, it's hard for me to gain true wind drift data on my range.
A SE wind is fairly blocked for close to 1/2 of the range, but there is a 150 yard stretch on the East side where there is a half bowl that really re-directs and seemingly magnifies the wind.
So a BC calculation from the shooting I do at my range would be nearly impossible.
A lot of the crops are off here now.
If I can find the time, I'd like to try so long range shooting again over at a relatives farm.
It is fun shooting at this distance though.
I work till the sun starts to go down, and if the wind is fairly reasonable, I bring out the Lead Sled and let her fly.
Powder is IMR4831 (lots)
.041" bushing
7/32" PFC
1:18 twist Pacnor barrel
My 28" .451 SavPac MLII shoots 300 MHs like this too.

Do you feel the faster twist helps with this? Do you feel the 1-22 twist can achieve this kind of accuracy or if you had this twist what bullet would you use, 275 mh?
Again can't believe how good of groups your getting, awesome, just plain awesome!

Again can't believe how good of groups your getting, awesome, just plain awesome! Thanks! I think a 1:22 barrel can shoot groups like this in slower winds, or with a trigger puller who is better at judging wind than me. (Which is pretty much everybody)  I have a Savage MLII, 25" .458 Pacnor 1:22 twist 300 MH @ 2700 fps, that I've shot 1/2 MOA out to 800 yards with. But that's with very little wind. The 327 MHs really seem to do well in the wind. The 1:18 twist barrel might have something to do with it, but I'd give most of the credit to the heavier 327 MH bullet. It's tough for me truly to say how well a 275 MH would do at that range, since I've shot very few of them. The best advice I can give, is to go try that load out at the range and see how it does in your gun. |

Thanks Earnhardt, another question for who ever can answer. I know this has been brought up but can someone explain the slower twist and faster twist to me as far as heavier bullet for faster twist or slower or slower twist for heavier or lighter bullet? Which set up works better for which bullet? Would this be a true statement--the faster the twist the better long range accuracy or not so?
What would everyone's experience be?

Powder is IMR4831 (lots) .041" bushing 7/32" PFC 1:18 twist Pacnor barrel My 28" .451 SavPac MLII shoots 300 MHs like this too. gotcha on the drifty range.. 3-5 mph quartering is not much wind,but with what you said a avg- 4.0mph @ 70 deg wind a .430bc would be approx. 8.7"//a .590 deflection approx. 6.0". if those target squares are 1" & if the wind was accurately gauged a .430 bc would have been off paper..not proven fact but something to note for future bc compiling on this projectile with that given speed. eventually you will have enough data to make a decent reliable prediction. with the above said I like to get out in the total wide open & shoot in consistent winds no matter what the mph & log results for each & every time out including 45-90 deg. angle winds. head & tail winds also have little surprises! hope you don't think I'm stepping on your thread. 3rd shot usually low.....almost always the same here like 99%---I think it has something to do with heat build-up causing a slightly different fps on that 3rd shot. keep up the great work & shooting! |

Which set up works better for which bullet? Would this be a true statement--the faster the twist the better long range accuracy or not so? What would everyone's experience be? Twist rate vs bullet weight is only a part of to equation. Key factors are bullet composition, ballistic coefficient, bullet length and bullet balance. Example a hornady xtp 300 gr will easily stabilize with1-24 twist then a 300 gr match hunter will stabilize with1-20 twist and if had a solid copper300 gr bullet would likely take 1-16 twist. There are some great twist rate calculators online such as jbm . |

Earnhardt and anyone shooting long range, curious what shooting style you are using. Hard hold or free recoil?

Group 2...The wind is making me look like a fool. Savage T/A .451 Pacnor 1:18 barrel 327 MH 3052 fps over Magnetospeed CCI-M 209 primers .041" bushing, 7/32" PFC Wind W-SW ~ 5-10 Wind blowing from left to right. On the first two shots the wind was ~ up to 5 mph, those are the two bullets next to each other. I waited a little longer to shoot the third shot to see if I could cool the barrel down to get the third shot to come up with the first to, since the third shots always seems low. Well...when I came back to shoot the third shot the wind jumped from about 5 mph to 10 mph The first 2 shots I held on the bullseye, the third shot I held about 3-4 inches to the left to compensate for the wind. Well, laterally the bullet is almost in line with the first 2 shots. But the faster wind ramping up the hill, pushed the bullet higher on the target. And I did not compensate for that. D'OH! Apparently when the southerly winds are around 5 mph or so, I don't have any vertical dispersion from the wind ramping up the hill. Any southerly wind faster than that, the more the vertical spread is going to be. 500 yards  Group 3... same gun and load 3055 fps over Magnetospeed Wind W-NW ~ 3-5 (guessing) Tonight the wind was a lot more consistent, than last night when I shot group 2 The vertical spread is ~ 1 1/4" again, so I don't know if I'm going to get any better than a 1" vertical spread. It's the wind blown horizontal spread that I need to work on. 500 yards  |
