Bullet weight isn't going to be a factor, it is a pressure issue. However since these bullets are mostly used in LR match situations shooters are pushing the pressures beyond SAAMI in most cases so it's likely that is the case.

QL and GRT are subject to Garbage In/Garbage Out but GRT is pretty easy to use. There is a lot of info on the Discord Site. It can be helpful in selecting powders but as others have noted it is not something to replace a formal load development. It will allow you to "play" with some variables...

Remember those published numbers are in 24”barrel so a 20” will run about 100 to 110 fps lower. I think I would try the VV 140.

A 20" barrel and >2600 fps is not something that is likely to happen with the 168 gn bullet. At least not without going above SAAMI pressure. Most of the H/IMR 4xxx are not going to make it. Likely CFE 223, BLC-2, and ACCURATE 2460 are probably the most likely to get over that hurdle.

I tried to test whether the ChargeMaster 1500 was rounding or truncating but I was unable to get repeatable results. I will defer to your experience. I think part of my confusion was brought on by the issue below. I have never seen a -0.0 on the Chargemaster and won't because of the auto zero...

If the display is 0.1 gn then Your drift will exceed 0.099gn before you see it. If the minimum display increment is 0.02gn then you see the drift when it exceeds 0.0199gn. EDIT: I BELIEVE THIS IS NOT CORRECT. THE MAXIMUM DRIFT IS 1/2 THE ABOVE VALUES. Interference is usually easy to detect...

Most electronic scale issues are associated with zero/tare drift and not calibration drift. Good laboratory practice is to re-zero the scale BEFORE EVERY SAMPLE IS WEIGHED. This is a step that is often omitted by reloaders. RE-ZEROING eliminates the potential drift issue and is a common...

@Woolsocks , we seem to have a never-ending discussion on ES and SD, small sample sizes and and all it entails. The above comments are correct and helpful. Let me add a couple of points: 1. No matter how many shots are fired the ES is made up of only two. In reality, ES has no statistical...

If you come up 11 MOA for 100yds then you need an additional 32/1.047/2 or ~15MOA additional to 200yds. Note that these are estimates and you really need to verify this on a range before taking this to a hunt.

The drop at 200 is not that sensitive to BC. At 1050fps at the muzzle your drop from a 100yd zero is about 32 inches and the bullet is dropping at a rate of about 0.5"/yard at that point.

I don't want to start a war here but I think it's improper to use the term "inferior design" when referring to different cartridges but it is important to understand that different cartridges were designed to have certain requirements, accuracy being among them but certainly not the primary...

The cannelure is set for 3.185" COAL on a 30-06 if memory serves me correctly. As noted Hornady Data is for 2.700" which should put the cannelure in the correct place. No problem if you set to 2.800", just don't crimp.

Unless someone is shooting at and you are down to your last round don't use the forward assist.

This sounds like a resizing of the base issue. First try the firing pin didn't hit the primer as the bolt was out of battery. Not knowing the history of the brass it's anybody's guess but the most likely issue is the case. I would not shoot this crap.

There appears to be something on the bolt (dark curved line) that corresponds to what looks like a gouge on the case head.

Actually I do not think the OP asked a question.

A little of the beaten path but important to keep in mind. @spife7980 brings up an important point. It's important to look at the target. It is often advised to not look at the Chronograph data but we seldom explain the reasoning behind it. Ballistically for a bullet to hit a target with...

It is pretty much worthless to state a SD or ES without stating a number of shots on which it is based. Realistically a ES is going to be in the range of 6xSD not 4 with a sample that provides a reasonable estimate of SD.

It's likely some of the AR fired brass will not be sized at the base enough for the bolt gun. This is where small base dies become helpful. You should invest in a 223 case gauge and use it to check each piece of brass, especially when going from one rifle to another. Also a word of warning...

@Rocketvapor I've worked off and on as a test engineer for over 40 years so I hope my comments will help. It's a valid point that your test may not have perfect statistical validity but that doesn't negate the results of your tests results based on your loads. I was going to run some...
