Shot some work up loads today of 140 Sierra Game Kings on top of Varget. Five 3 shot groups averaged .733" CTC @ 100Yds.

Here is a couple of the best groups.


Also shot some work up loads for 150 Grn Nosler BT's on top of Varget. They didn't shoot as tight as the Game Kings but even so overall Average group size was just a little over an inch. Maybe I need to try the 140Grn BT's

Can I ask what kind of dies and what kind of runnout your loaded bullets had. I've kind of had an argument over at another forum where people are pretty much saying not to expect good groups without using "competition dies" and "zero" runnout. I sure get irritated at these kind of people-----but then I guess I irritate them when I tell them they are full of bologna too!!

Hey Karky I know just the kind of people you are talking about. And it pisses them off when my 7.7 Jap with 180 grain Sierra Pro hunter bullets shoots constant .375 groups using an old RCBS press, standard lee dies, Norma cases, Federal 210 primers and the old standby IMR 4064 powder. They laugh when I come to the range and cry when I leave after waxing thier ass with the old war horse made in 1940. First shot just take your time and work on a load. The 7m/08 will get to .500 quick when you tune it in.

Well, I guess the "competition dies" and "zero runnout" folks will just have to add me to their list of folks that irritate them as I don't have competition dies (Standard Redding) and I even had to go do a search to find out what "runnout" was. (So obviously, I don't have a concentricity guage)

To top it off, I'm shooting a straight out of the box Remington 700 Mountain LSS. I did lighten the trigger to 2 1/2 Lbs but other than that, she's straight from the factory.

The .733 was with various powder charges. She obviously likes the 140Grn Sierra Game Kings & Varget. I'm gona load up a bunch at 43.5 & 44.0 & shoot some five shot groups to see which holds up the best. I'm fairly certian the overall average will be in the 1/2" or less range.

Got to work up a Nosler Partition load as well......love those partitions for deer hunting!!!!

That's what I love about reloading....you just get to keep on tinkering!...LOL..

Don, Competition dies, what a crock, my Lee Dies work great. My 700 S/S shoots in the low 4s for 5 shots with 150MKs, 38-39grs. RE15, 9 1/2 primers, same for the 150 BTs and 39.5grs. Varget, CCI primers. BTW, got a 1.5" 3 shot group @300yds. with the latter.

First shot, Try RE15 with the Sierras, Varget didn't work for $hit with the 150MKs, don't know why. And, go to the Remington primer or CCI, never had good luck with the 210M primer. I see also you've gone past max according to the Sierra manual. Accuracy load for the 140GK is 39.6grs. RE15, yeah, they use the 210M primer, but I'd still go with the Rem. primer. Still is good shooting for a skinney barrel. Do you let the barrel cool a bit after the 2nd shot? My S/S is too hot to touch after the 2nd, and usually always throws the 3rd shot, and it's thicker than your Mtn. barrel. First 2 shots are usually in the same hole. Jay

First Shot--from my experience, if you haven't found the "sweet spot" in terms of seating depth (how far the bullet is off the lands) then you most likely have a lot more potential accuracy that is realistically achievable. Get a Stony Point tool and accessories and load up 3 rounds with the bullets seated .005, .015, .025, and .035" off the lands. Shoot them, then try again with 3 rounds of the best load, 3 rounds .005" shorter and 3 .005" longer to bracket the best load. Shoot them and see what you got. Only potential fly in the ointment is if your barrel prefers the bullets seated really close to the lands and the resultant long cartridge won't work through your magazine. Good Luck and let us know how it goes. Only rifle I've not been able to make shoot was a 7-08, a Rem 700, Hart barrel, trued action, lapped lugs, bedded, good trigger, etc. Even after cutting a quarter inch off the muzzle and recrowning, cutting 2 threads off the other end and rechambering, still shot .375" one day and 2.5" the next with the identical load in the same pieces of brass.

FWIW, When I loaded the 150MKs, I just set them @2.800(.010" off the lands) and went shooting, first group went.426", with the 150BTs, didn't matter if they were off .010" or .020". I don't believe seating depth plays that much of a role as most people think it does. I do believe the right bullet makes more of a difference. Jay

Try a 160 grain gameking on top of H4350 EXT and the groups can get much tighter (3/8).
I use an old Rem 700 varmint cut to 20.5 inches and glassed bed with floated barrel. The dies are old RCBS dies that I bought with the rifle 20 yrs ago.
I use CCI 200 match primers, Remington brass and 43.8 gr of H4350EXT.

I did ease up past max on the varget. The Sierra manual says they used a 26" barrel and I'm shooting a 22" barrel. I worked up in .1 grn increments from 43.0 to 43.5 then shot a group at 43.5. Did the same from 43.5 - 44 and shot another group. Had absolutley no pressure signs whatsoever. Probably should have put a notice on my original post advising those charges were over max.

I'll definitely give the RE15, and Remington & CCI primers a try.

I was letting the barrel cool 2 Min between shots although I don't know if it really needed is. My barrel is just starting to get warm after the 3rd shot.

I'll give it a try. Will probably do so with the 150Grn Ballistic Tips. I'd really like to get them shooting better. I've got a Stoney Point and currently loading 10 thousants off the lands.
