I used to shoot 46 grains of RL17 with 162's and 168's for a bit over 2700 fps from a 22" barrel. As always, work up for safety's sake.
And if you really want to just keep the rifle supersonic as long as possible, you might want to try 195 bergers, 183 sierras, or the new 180 hornady.
The only 7-08 I've worked with easily did 2700+ with 162's in a 22" barrel. I've wondered about the 180's and 195's, too. If the BC on the new Hornady 180 is legit, it and the 195 Berger aren't going to beaten by anything in this case for wind drift.
1710 fps at 440 yards wasn't slow enough? And I don't like that idea because rotational velocity is a contributing factor to expansion, and reducing your mv also reduces rotational velocity. A bullet starting out at 2600 fps that has slowed down to let's say 1200 fps when it impacts jugs will be...
It could vary quite a bit based on your elevation. At sea level, they might keyhole. In Denver, they'll probably fly fine but with a little BC compromise. At the range I used to live next to that was at 7800', they'd be perfectly stable.
I caught a couple bullets today. First was a handload that clocked 2614 fps on its way to the jugs at 25 paces. It made a tiny dent in the back of the 3rd, but the jacket and core were laying in the bottom of that jug. Combined weight for the two pieces is 68.2 grains. It looks just like I had...
Of the powders you mention, RL22 will almost certainly give top velocities. Not 100% certain, but I think 61 grains is a popular load for 200's with that powder. I like 54ish grains of RL17 behind a 200 AB. It gives a little over 2700 in a 22" barrel and is accurate. Stole that load from someone...
My opinion is that you can't beat Retumbo in the 7RM- with any bullet weight. It consistently provided both top accuracy and velocity with everything from 140's to 175's for me. I pushed 140's to 3400 and 162's to 3150 looking for pressure signs and never saw any. Accuracy was acceptable to...
Well, I just sold all my .338 brass and bullets. Probably keep the dies though. Just in case... ;)
So now, do I get this new barrel in 6.5-06, .280, 30-06, .264 WM, or 7mm RM? It's a savage, so switching bolt heads won't be an issue. My magazine limits me to 3.450", and I'd rather be nowhere...
Mike, I bedded the 30-06. And it shoots well. But only with certain loads. And every bullet weight impacts several inches apart from each other. And it gets hot, fast. I like to shoot. A lot. Shooting 3 rounds in 10 minutes and then putting the rifle away is not for me.
And when it comes to...
About what I figured you two would say. :) So, my 30-06 featherweight that's a finicky pain in my butt due to the thin barrel should hit the road and my .338 that just got a new stock and could use a new barrel should become a 30-06 or perhaps 7mm Rem...
The thread on 30-06 vs 7mm RM got me thinking...
A .338 WM is basically a big 30-06. It will push a 250 grain bullet to about 2750. Or at least that's as fast as I can get mine to push a 250. 200's don't quite get 3K in my rifle. And 185 ttsx's, for whatever reason, don't really go much faster...
My 30-06 didn't seem to care much for 165's or 180's, but shot some incredible groups with 54.5 grains of RL17 behind a 200 accubond or 58.5 grains of Ramshot Big Game behind a 150 TTSX.
There's a member over on 24hourcampfire that has gotten some very impressive results with R17 and 215 Bergers in a .308. Seems to be the way to go for really long range shooting. I believe he was getting good accuracy out to a mile...
I had good success with 69.5 grains of H1000 and 72 grains of Retumbo under either a 162 a-max or 168 lrab. H1000 got about 2950, Retumbo got about 3050.
