Thank you! There was actually not very much bloodshot meat, surprisingly minimal. I discarded perhaps a 2-3 lbs, but mostly because it was full of small fragments of sharp bone.

YW, and thank you for the good bullet, Steve. It performed great, and was accurate for me without much load work. The bull had busted his rack in mutiple spots (surely while fighting). The left side main was busted off prior to the 5th, and the right side 5th was also missing a couple...

Had the opportunity to use a hammer on a bull elk over the weekend. Worked well! Near side shoulder was broken up. I used the gutless method, so I didn't examine the organs. Found the bullet base embedded in the opposite hide. Bull Elk ~440 yds, broadside 6.5 PRC 131 Hammer Hunter @ 3150...

I made them. Fairly straightforward to do for your rifle if you're curious. I used Excel, but google sheets would work too. Generate your ballistic trajectory for horizontal fire using your favorite ballistic calculator. I used JBM web calculator Calculate your RR or IRR correction for...

I tried to simulate these new bullets in QuickLoad to see what it suggests. (Full disclosure, I am not a QL expert by any means, and it's totally possible I am missing something). I assumed that the increase in speed would be due to reduced engraving pressure of the bullet entering the...

There are a couple common methods used, with varying accuracy. Rifleman's Rule. Seems more common, but it not very accurate. Shooter gets MOA values from their 0-inclination range card for the horizontal distance range. Improved Rifleman's Rule. What Dog Rocket explained. This method is...

Nope. I'm sure I'll never find the terrain in MI to shoot this test. That said, the ballistic calculators provide significantly different solutions for the same inputs - we know that at least one of them is wrong! Thanks for the extra datapoint. Let us know if you ever get an opportunity to...

You are correct. :)

I take it you were using 4DOF? How high were you hitting, and with what cartridge? Extrapolating my chart via eyeball method to 1200 yards, 7mmRM would be about 35" high compared to the JBM calc.

Bumping this thread, looks like Hornady's ballistic calculators still disagree with other calculators when calculating solutions for uphill/downhill shots. Ran some more detailed numbers today for a 7mmRM in both JBM and 4DOF. The difference between the solutions becomes VERY significant at...

Also, if I may offer the following recommendations - no need to use them. Just a thought. Instead of a single column for "Caliber or Action Length," separate it into the following three columns: -Action length -Cartridge -Caliber This would allow a user to sort the list using criteria such...

Hi Muddyboots and djfergus First off - excellent idea to create this! Second - you can upload an excel file. But you have to put it into a .zip archive first. LRH allows .zip uploads, but not .xls. Much appreciated if you're able to upload the excel doc. It would be very nice to enable the...

Browning X-Bolt 6.5 PRC. Factory DBM. I load to 2.983" I think the mag is basically right at 3", but I don't want to risk them jamming up. You'd also need a bullet with a pointed nose (rather than too wide of a flat front hollow point), as the magazing comes down to a point at the front.

Stgraves, While the chart you referenced isn't wrong (and is a helpful contribution to this discussion), you are indeed using it incorrectly. What that chart does is allows you to easily calculate the horizontal distance to the target, knowing the shot's inclination angle and line-of-sight...

Did you dial/hold for any wind on the 503yd shots?
