reading about thermography etc., I see that to get a proper temp reading you need to enter in emissivity and the reflected temperature, and there is this whole procedure to do that, if you are using thermal imaging to accurately measure temps of various things. But in rifle scopes, we just want...

well look and see what happens to 175 SMKs at a much closer range of 900 yards. When I went to paint the 900 steel I found a bunch 175 SMKs just laying in the dirt. Some had bounced off the dirt, some off of wood beams nearby and others maybe off the steel target. But clearly as you can see...

I had to get myself a Lee crimp for reloading solids like the Barnes TTSX on my 308 (California Condor zone for hunters requires lead free ammo). Reading thru the manual for the die, Lee said that crimping (better) equalizes the 'start' pressure of the cartridge burn cycle, leading to much...

I am not having good luck with Shooter app on my 338LM firing Scenars (250 and 300). Shooter predicts a comeup about 1.2 MILs short of the actual. Meaning I need to add about 1.2 MILs to actually hit the target... this is at a mile roughly (1800yds). Is anyone using Shooter with these bullets...

I just put on a S&B PMII MIL/MIL on my 338LM with 40.6 total MOA base (20 on the Pic rail, and 20.6 on the Spuhr mount). When I first went to zero in and set the elevation turret to zero, I found that on the second turn of the turret, I could only get to like 19 MIL total, and 26MIL is the...

Tried to do a quick OCW test this afternoon at 100 yards, with my 338LM. I had to go zero in a new scope and mount (Spuhr 34mm... very nice kit). The results are in the following image. It's all marked, but bullet is 250gn Scenar, powder is VV N570, Fed 215M, Hornady brass, 50deg F, Steyr...

I'd like to understand the effects of my RCBS Chargemaster being accurate to the 0.1 grain. So can someone with Quickload tell me what the difference in MV would be between say 44.0, 43.9 and 44.1 grains of Reloder 15 powder. Pick a 308 case size that you know of, Fed 210M primer, and a 26"...

with my S&B PMII 25x scope zero'd at 100 yards, I can dial up the scope elevation turret twice around, up to like 68 or 69 MOA up. I forget the exact number, but there seems to be a hard stop there. Probably because there is no way to know if you are doing around the third time, for you S&B PMII...

got a copy scanned in of the March 2011 edition of Tactical Weapons review of the Steyr SSG08 in 338 Lapua Magnum. It's a pretty thorough review, but the manner in which I scanned it created a 40MB file, so not sure if I can attach it here. Let me know and I can email it to you or post it...

apologize if this has been posted elsewhere... has anyone tried this new magnetospeed chron? Looks quite accurate and uses non optical methods to measure speed, which implies increased accuracy. More expensive than my CED, but if it actually works all the time, that would be worth the cost. My...

Have you read or heard about this... here is a sort of obscure (at least to me) website from a guy in Finland about this phenomenon. Worth a read... the actual discussion is closer to the bottom this web page. The author seems like a wealth of interesting firearms info...

I have recently purchased 4 boxes of new Lapua 338 Lapua Magnum brass from someone on gunbroker.com, has got high ratings and sells a ton of stuff, so let's assume for the moment that he's telling the truth and not a dangerous scam artist. He says he bought the four boxes (100 count) from...

I wanted to test limits of the Bushnell Elite 1500 laser range finder (LRF). Took it out to an abandoned air force base yesterday where finally I could find alot of uninterrupted flat land with some structures at appropriate distances. Result is I could range the control tower at a max distance...

so I have been seating my 308 bullet depth on my Rem 700 Police to about 20 thou off lands. Given some very good results with much deeper seating on my 338 Lapua, I decided to try the same with my Rem 700 308 rounds. I was seating about 0.020", and then today tried 0.100" and my ES (was like...

I have Shooter, it's great. I also have downloaded and ran Lapua's QTU, using Lapua radar measured Cd's. But that Lapua version of Quickload has one really stupid limitation, which is the atmosphereic conditions for shooting day are copied from the atmosphereic conditions for the sight-in day...

trying to figure out why my MV ES is as high as it is (40-50fps), given I make sure that my loads measure exactly the same each time on my RCBS scales. I even double check the throw on a second RCBS model scale and they match perfectly, well to the 0.1 grain digit, and the spec for this scale...

works pretty darn good. I am using it with VV570 (very long cylindrical kernels) and it rocks on trickling out exact loads. I double checked using a RCBS 750 digital scale. The RCBS Chargemaster scale doesn't drift at all like the 750... and the auto dispense function is really a neat trick...

nice discussion, worth a read. Gets pretty technical in a mech eng way fast, but still understandable for the average engineer. http://technology.calumet.purdue.edu/met...e%20Chamber.pdf the same site has a nice discussion about hammer forging barrels and what it does and doesn't do for accuracy.

have a Remington 700 338LM that shoots great. No problem there. But I like the idea of moving to a 1:9 twist and longer barrel since I want to exclusively handload for 300 and stop building 250s. I haven't found any substantive reviews via google... so wondering what you all have thought or...
