The barrel was really clean, prior to the 30 that came before my tests.
So no one thinks that it could be a seating depth issue? The bullets, in the ones tested above, had quite a jump to the lands.
Sorry, I should have been more clear. By slowly, I meant about a minute between each round. With it being 40 F today, that was sufficient to keep the barrel cool.
I have fired 10, five shot groups of this particular load, and there is always one shot that opens the group up (from what would be a .5" group) to an 1" to 2.33". I'm quite confident that the shot isn't pulled, as I'm shooting from a bench with a bi-pod in the front, and sand bags in the rear...
I do have IMR 4350 on hand, and will start with that when the 90gr bullets arrive.
I generally load with bullets from Hornady and Sierra, but really want to try some of the offerings from Nosler. Thanks again for the help.
I think you are right about the heavier grained bullet, but I am also sure that with proper shot placement 80br would be sufficient.
Just out of curiosity, aren't the 80gr Ballistic Tips Spitzers and 90gr Ballistic Tips Spitzers the same bullet, obviously except for the weight? My apologies if...
Both the action screws and scope mount/base screws are all properly torqued. I don't think that is where the problem lies, although I have yet to bed the action for this rifle, something that I am sure will help as there is a very generous channel for the recoil lug.
All shots have been taken...
The only reason that I didn't try the RE 15 is because I have always been told that it's temp sensitive. I see that you are in MN, have you found this to not be true? I do have it on hand, and love it for 168gr bullets for .308, maybe I will give that a try next.
Just out of curiosity, what...
Loading for the .243 Win. I have tried three different powders, in various grain weights and COALs, but have yet to get a five shot group under an inch and a half at 100 yards. I really would like to have my son use these on Whitetail this year, but am about ready to give up. So far I have...
Excellent, thank you. What program did you use for your data? My original intent was to start with 39gr and bracket it in .2gr increments up and down from 38.8 (38.2-39.4) and go from there. It's nice to see that is well within estimated ranges.
Thanks all, I appreciate the help. I'm a...
JD338, thanks for the links. Although the Hodgdon site doesn't specifically list the 80gr Nosler bullet, I can extrapolate with the data from that site. Thanks for the BC info as well.
Another good free ballistic calculation site, if you've never tried it, is JMB Ballistics. It provides...
Does that 39gr max load show a muzzle velocity of 3300 FPS? The info shown at the nosler.com site lists 39gr, but unfortunately doesn't give a max load. http://www.nosler.com/index.php?p=15&b=6mm&s=133
Could I trouble you for a similar load using Varget? Perhaps 3200 FPS, and 3300 FPS...
I am loading the 6mm Ballistic Tip 80gr spitzer bullets for 243 Win. and will be using H4895. Does anyone know what the max load for that powder/bullet combo is? I'm not looking to load to max load, but want to know what it is, so I can use caution if I approach it.
And lastly, what is the...
