Re: Learning to dance with my big girl.....

Went shooting last weekend with BJ and the 270AM. Wind was around 30-35mph but we had to re confirm drops before deer season opens this weekend. We had a gong at 500yds and grapefruits at 675yds shooting directly into the wind. FIrst shot on the 500yd gong was as close to dead center as you can get, on too the fruit. My first shot on the fruit was about 2" off at 2:00, still would have laid out a deer. NExt shot scattered grapefruit rind over a 20ft circle, on too the long stuff. We had another gong set up at 980yds shooting into a direct crosswind. After a sighter shot i lined up on the 12"x12" gong, I was dialing for elevation and using the NP-R2 reticle for the windage. I was holding 6.5moa for wind and 14.25moa for elevation, the trigger broke and even over the howling wind I could here that beautiful ring. ANother shot followed up for back to back hits and I was happy and ready to get out of the wind. THis was closing in on the 850rnds down the pipe mark for my 270AM so I am still pretty damn impressed with the accuracy.

Just thought I would chime in a with a little Allen Mag shooting story.

Finialized mine for hunting.....

Well we have been playing with this and that, and as Kirby referred to, myght have some minor addiction going on.

However, with our conditions down here we have had to drop loads and figure on lower BC to get somewhere in the parki of where we want to be. I settled on a load of 92.5gr of 869 for the 169.5, and 94gr of 872 for the 195's. Both are being lit by the Fed. 215M primers and have done great so far. I am totally confident out to 800 yds and figure that even out to 1150, which is the furtherest we have shot so far, I could hit a hog if a good shot were presented.

this past weekend I set up paper at 200yds and dropped the zero on the 169.5's to 1" high there which allows me to use the bars out to just over 1K. I am going to leave her be for now and concentrate on getting something or multiple somethings for the rest of the year. With the groups I have gotten so far, anything that shows out to these ranges is in serious trouble. Look for some reports coming soon.

Well, I\'ll think I\'ll do what Kirby says from now on......

Got some shooting time on the 270 AM today.

Zero'd @ 300yds then shot @ 500.

The Conditions:

Today's temp. was 36* w/2mph wind from 29* and was shooting towards 0*.

Humidity was 96% w/fog/mist so you couldn't range to 300 yds @ times. Just kind of a mist in the air.

Hg was 25.569 here and 30.009 @ Sea Level.

I don't know what all of this mean but I think bullets should have a lower BC on days like today.


169RBBT ahead of 99gr US869 and Fed 215 GM primers. MV was 3275 the other day when I chrono'd this load.

195RBBT ahead of 97gr US869 and Fed 215 GM primers. MV was 3200 the other day when I chrono'd this load.

"The other day" was 4* warmer than today.

My computer gen'd drop charts for both bullets track together to 500yds.

There is no more than 0.2 MILs difference out to 1000yds.

At 100yds both loads for all practical purposes grouped together.

I used the 169s to accurately zero @ 300 and fired 1 195gr load to verify that it grouped with the 169s. It did.

I went to 500 yds with the 195s and grouped well enough to show that it was shooting 0.1 Mils higher than calculated. Group was nearly in the center of the 1st Mil dot instead of -1.1 mils which the bottom edge of that dot.

I had no 169s to shoot at 500 but they were spot on (-1.1 Mils low) at that distance the other day.

If I'm shooting accurately enough the 195 may be 0.1 Mil (~2") flatter than the 169 @ 500. One more drop chart check w/the 195s @ 600 and 1089 (that's where the gong is) and I'll have Rock ready to throw.......lead.

My problem is I have the same level of confidence with "Pink" (338 RUM) as I do with "The Rock" (270 AM)

Pink shoots a bit of a rainbow with the 300 SMKs @ 27XX but she's spot on. The AM is steadier on the bipod and most probably a bit better to shoot out towards 1K (10lbs vs 11.8 lbs). Wo is me, decisions, decisions, decisions. Guess I'll have to make more rules. W/a straight 16X on the AM and a 4.5-14 on the 338 I guess it depends on if I walk & stalk or set up a hide.

RE: Listening to Kirby. He said not to turn the necks. Hell, even I knew that didn't sound right. [img]/ubbthreads/images/graemlins/blush.gif[/img] Yeh, right [img]/ubbthreads/images/graemlins/frown.gif[/img]

If I ever turn 'em again I'll just shine them up enough to satisfy my "tinkeritus). Neck tension seems to be important. [img]/ubbthreads/images/graemlins/blush.gif[/img]

I won't neck turn the next batch but it may be awhile before I wear these out as the above listed loads show no no noticeable primer pocket expansion or extraction pressure. After tossing the cases w/too little neck tension I have 15 out of the original 20.

I'll work out ALL the bugs w/these cases before I prep the other 100 or so.

Re: Well, I\'ll think I\'ll do what Kirby says from now on......

This past Friday was so beautiful I just had to leave the big city early to go north to the farm.

Set the 270AM up on the table to verify load drop at 1150yds to where we set a feeder up. My load dope was right on as I cut a 6.5" group with the 169's. The wind was horific as the strike of the first 2 rounds were 48" to the right. Came back to the bench and held 48" to the left and the strikes were 24". The problem is so many different up draft currents and warm and cold pockets with swirling winds from 3-8 from bench to mark. The wind is going to be a real learning curve and challenge. But that's what makes this sport fun,

Hmmmm, (48/11.50)/1.047=3.9865 MOA or 16 clicks into the wind.

What if you had a target area some distance to one side or the other of the feeder that would reveal bullet impact for a sighter shot. At very long range around here it is possible at times to shoot a sighter and the game isn't spooked at all. Then all ya gotta do is wait for those conditions to come back. Yeah, right [img]/ubbthreads/images/graemlins/crazy.gif[/img] They hardly ever do. [img]/ubbthreads/images/graemlins/frown.gif[/img]
