Hey guys. I'm pretty new to precision shooting, and have my rifle zeroed. I get 1 MOA or less groups usually, however that's after a few rounds. How come my first few shots are larger groups? I'm talkin 1.5-2"@ 100 yards ... Which is kinda scary if I'm wanting to take an 800 yard shot. I just got back from the range with the best group being around 1 MOA (around 50 degrees, 15-20mph gusts) and I'm happy with that. But my first few shots (first shot was down 1.5", left 1.5" id say) were pretty big (1.5"-2")... Is this normal?

Re: remington 700 coldbore...
Had the same problem, turned out not to be a cold bore. Lucky enough to have a friend that is expet benchrest shooter and I let him test rifle and found that it was me not rifle. Might be worth trying. Might help if you post type rifle you are shooting.

Re: remington 700 coldbore...
What caliber ? what model
Do you oil your bore after cleaning ? leave residue behind ?
Do you shoot Molly ammo?
What is your bedding ?

Re: remington 700 coldbore...
Main question is how is your cleaning? Other thing is it might not be the gun but you warming up and it takes you 5-12 before u start becoming consistent . Lo of cold bore issues can be a cold shooter

Re: remington 700 coldbore...
I wondered that dj! It's stock bedding, .308 Remington 700 sps tactical, FGMM 168gr, 100 yds, no moly bullets, only have 120 rounds through the barrel, after I clean it i run a patch through with a small amount of oil on it, then I run a dry patch through it.

Re: remington 700 coldbore...
I clean it by running the brush through it ONCE, then I run 4-6 patches with solvent through it... Then 1 dry one, then 1 with oil, then a dry one. Is this how you guys do it?

Re: remington 700 coldbore...
No. My 308's get cleaned every 300 to 500 rounds and cold bore shots are not an issue. Now I handload exclusively and my load really does not leave a lot of crap in the barrel.

Re: remington 700 coldbore...
when your cleaning the only thing that will really cause a shift is taking excess copper out. i clean em out to take out carbon. if this is your issue its not a cold bore issue but a clean bore issue. best is to let the barrel run until you get an accuracy decline then clean. I would stop cleaning it so much, and when you head out to the range really apply your fundamentals on your first couple of shots. I bet you will notice a lack of shift. if so you know its a clean bore issue and you need to focus every time you send a round.
best of luck

Re: remington 700 coldbore...
Thank you guys! I think you're right. So how often should I clean? 300-500 like he said? Will leaving it dirty cause corrosion over time? I also heard that military snipers put a lot of ammo through their rifles (without cleaning) before they go on a mission/out in the field

Re: remington 700 coldbore...
There are some that say the cold bore shot is a myth. They say it's a cold shooter. Do you do any dry firing drills before sending your first round down range?

Re: remington 700 coldbore...
I never oil any bores unless they are carbon crMo Barrels and before long storage periods.
I have found no problems with cold bore cleaning with less the 100 rounds, just dont leave any solvents behind. You want dry and clean

Re: remington 700 coldbore...
No I don't warm up, ill try that next week though. I'll try a dirty barrel though for sure. If I put 20 rounds through it (to get dirty), then wait for the barrel to get cold (from the outside temperature) will that simulate the "coldbore" as if I waited an entire week?

Re: remington 700 coldbore...
Stop cleaning it.
If you have to, clean it before you leave the range and then fire 10 rounds.

if you want to simulate cold bore wait until the chamber is the same as the ambient temp outside. not so much a time hack to say when a bore is cold. but this will only be a coldbore not a cold shooter lol you will be warmed up
but honestly if you shoot with a dirty barrel and have no decline in accuracy its you lol.
hope this all helps. def post a range report after you apply this

Ok. So ill just run a couple patches just to get out the carbon from now on. Can you believe 13k rounds in a .338?? Isn't a .338 life like 3k?? I'll take his advice for sure

Re: remington 700 coldbore...
This is a very interesting topic to me.
I went to the range on Saturday and fired off about 60 rounds of .308. Went home and cleaned my Remy 700 AAC-SD...I bought it in late November so it's had a total of less than 140 rounds and I would clean it after every session. I am a novice shooter, this is my first .308.
So this morning I went back to the range with my newly cleaned rifle and the first 3 shots @100 yards were nowhere to be seen on the target. They flew far right...far far right, a good 8-12". Gradually the shots started to center. Granted I was using the factory AE 150gr FMJ but I didn't expect it to be that bad. I then switched over to the 168gr Federal Gold Medal Match SMK's and started to get some groupings. As you can tell by the photo, I am by no means an expert marksman but I wouldn't have expected my first shots to be that far off...who knows maybe it was me, early chilly morning, wiping the sleep off my eyes, etc etc. But I won't be cleaning the bore any time soon and I'm curious to go back next week and repeat the process with the dirtier barrel to validate.

B&C Tactical Medalist M40 stock
Smith Enterprise muzzle brake
Harris BRM 6-9 bipod

Re: remington 700 coldbore...
On the FGMM: That's you, not the rifle. Because the vertical is huge, but the horizontal is acceptable for 100, so you should be able to hold those groups to well under an inch.
That leads me to believe that you don't have a rifle problem.
As to the American Eagle, it will tell you absolutely nothing about anything. That picture shows split groups, not a group. There's no way that cold bores which legitimately deviate from subsequent shots also group for three or four more shots and then move POI (as shown in the pic).
If you have a cold bore deviation that sends the first shot that far away, then you have a gun problem (or a suppressor attached). But I don't see that here - yet.

Thanks! I think maybe I just need more practice. I did notice more reticle movement than I recall, I'll play around with the parallax. But damn playing around is expensive with the SMK's. But this is all off-topic since it appears all to be me. Hahaha

Re: remington 700 coldbore...
I would ignore the American Eagle groups and look again at the FGMM groups. See the vertical? Stop breathing, then break the shot. See if correcting that alone doesn't cut that vertical in half.

I try to follow the BRASS shooting technique but still working on it. I run out of breath trying to get the reticle still and I have to repeat. Never thought I'd get winded sitting at the bench. Hahaha. Thx.
