I have a question for all of you pros out there. I recently purchased a new ML-10, syn. stock with a blued barrel and a Luepold ML scope. I'm shooting 43 gn. of N110 and a SST 300 gn. .45 cal using MMP-HPH 12. I've put approx. 100 rounds though this rifle with inconsistent accuracy. Now my question is...the first 2 shots are dead on at 50 yards. My 3rd shot does not even hit paper and the 4th shot as well. I'm trying to work out the loads, but I believe a hot barrel is to blame. I'm wondering how much a hot barrel will affect accuracy in these rifles. Now back to my question. How long should I let my barrel cool down before the next shot? I've been shooting in the sunlight and temps around here when I shoot are anywhere from 70 - 85 degrees in the morning. I appreciate any help I can get. BTW, love the site.

Hot barrel for sure, and with higher temps and 43 gr of 110, possibly blown sabots. In the temps you describe many waith 15-20 minutes between shots. Because this is a PIA, many of us use cool rods, and a search will bring up a lot of info for you.
Temp most certainly sounds like your issue.

I'm also new at this but I think that your barrel is too hot. You might look at getting a cool rod.

Let the gun cool 15 minutes between shot when shooting in hot weather. You also might try backing down the charge a few grains for hot weather. If you are blowing sabots then clean the gun real good to get out small pieces of plastic. With a 100 shots of N110 you might be ready for a new ventliner too.
Read the tips and hints section at the top of the page too. Good luck, Mike

If you dont want to go the cool rod route, take a 22cal with you and after the second shot out of the savage, put it down and shoot the 22cal for at least 12-15 min, touch the savage barrel where it will be the hottest, where the breech plug screws in, if it is still warm drink some water shoot the other gun and wait. You normally can get 2 off in a row here in Tampa before the group goes to hell. Sometimes i take 3 guns, 22cal, 17hmr with the accu-trigger, this rifle allows me to practice squeezing the trigger and it has made me a better shot with the 10ml.
YOU HAVE TO WAIT IF THE BARREL GETS HOT!!! Trust me here; it does get hot in Florida in the summertime. I have not shot the 10ml since April but I will get Old Betsy out Oct 1 to get ready for deer season and take at least one other rifle to shoot as the savage gets hot

definatly need to wait. i have found in thoes temps that 15 mins is a good period. look for sabots after you shoot. if all you find is shreds. then you know you are blowing sabots. i also agree back down a grain or 2 in hot temps. you may find even better accuracy. if i remember correctly, alot here have found their best accureacy at about 42grns if VV N-110.

When you are letting your barrel cool down make sure your components are in the shade. Heat softens sabots and can easily cause you to miss paper at 50 yards.

Anyone try dry ice to keep the bullets in?

Anyone try dry ice to keep the bullets in? You mean to keep the bullets cold? Don't think that's part of the issue, as guys shoot sabotless shot after shot with no cooling time or cool rod use. I think Boarhog has kept his sabots in a bag in a cooler when it's real hot, but you really need to keep the barrel cool between shots when shooting saboted or accuracy is usually guaranteed to suffer.
