I have a 700 5r 24” that i am playing with. First trip the range, after sighting in with two rounds (i am starting to like the Horus reticle), i settled down and shot a 5 shot group at 100y off a bipod and bag, 175 GMM, that was under an inch, all touching, no fliers.
Stupid me with my pages of notes and working on a new rifle, i took a photo but never measured it. Suffice to say an inch tape circle would have covered it with room to spare.
I chronoed the factory ammo and have that in my notes.
Its a 700 5r, 24” braked barrel, timney 510 with a Grayboe Ridgeback stock and a Bushnell HDMR2 scope, Horus reticle. For now, a Harris with podlock and a rear bag.
My goal is to work up the best load for my intended use, first, just playing with an accurate rifle and trying to eek out more accuracy, secondarily, once i get the drill down i intend on entering some local mid range matches, like they run in Burbank i think. I dont think thats paper matches, i think thats on metal, so whatever difference that makes.
I have a rock chucker for my precision rifle loading, picked up some lapua 1x brass, bought some competition dies, have plenty of 4064 and 175 mk projectiles, a case length gauge with ogive insert for 308, and i am about ready to load some “lets see how THESE work” rounds.
So i used the case length deal and it looks like the 175s touch the lands at 3.320 to the ogive.
I think that means i should start loading at 3.300 to the ogive? Is that correct? Which way do i go with that, +/-, to see if thats the sweet spot?
Its a good deal longer than a factory round, i think i will have mag clearance issues.
How does one deal with that? I have a single shot sled ive used to simplify loading during load development. I dont mind using it but being locked out of magazines seems a pretty hefty trade off.
Do people work up a load that is the best they can run, then another load thats the best the rifle will feed through a magazine? Or just load the same charge weight, but shorter to run in a mag? Am i going to note a difference? Should i load as long as will run in magazines, or find what the gun likes?
I plan to run a ladder test at 300 at angeles, unless i go to the desert, thats as far as i can set up paper that i know about, and its a 3/4 day trip to do that.
I appreciate the input.
