[QUOTE="Nimrodmar10, post: 1846441, member: 36369"] My first trip to the range was enlightening. I had plenty of rounds loaded for my rifles, so I used them for break in and sighting in the scope. I put a Nikon Prostaff 5, 2.5-10x40mm scope on the pistol to use for group testing. The load was the Hornady 140 gr. ELD-M loaded with 41.3 gr. H4350 and a Federal 210M Primer in Hornady Brass with an overall length of 2.813" . From my Savage rifle with a 26 inch barrel, this load chronographed an average of 2752 fps. It wasn't a maximum load, but was a very accurate load, normally shooting under 1/2 inch. Fired from the 12.5" barrel on the Remington 700 CP, it averaged 2273 fps. That is 479 fps slower than the 26" rifle. With a difference of 15.5", that would be a loss of 30.9 fps per inch of barrel length. This was about what I expected. After firing 30 rounds for barrel break in, I removed the two screws holding on the M-Lok friend so that I could attach my Magnetospeed chronograph. With it attached to the barrel, the groups averaged just over an inch at 100 yards. I purchased some Hornady 95 gr. V-Max and Nosler 120 gr. Ballistic Tip bullets to try next, with some faster burning powder. [/QUOTE]
