.270 Win 150 Partition

Bruce it's hard to go wrong with the 6x36 Leupold or the 6x42mm Leupold. Both are fantastic scopes and I've never felt at a disadvantage even at close range with the 6x.
 
Thanks again guys, and great input. OT- I can't seem to hit well past 300 or so with a light rifle like the Mountain rifle. I missed about 6 nice pronghorns in one day out near Laramie, all around 300 to 350. The wind was a major factor on half of them, the rest was me...I just couldn't get still. From that I found that a sporter weight with good glass ( anywhere from 3x9 to 4x14) worked better for me out in the open. I like to use a Mountain rifle as a stalker, usually I will hunt along the edges of aspen/black timber...like one would with a 30-30 almost, ha. I guess growing up in the Big Thicket in East Texas and bowhunting for years made me this way! If I know I'm looking at longer ranges, I take the heavier rifle/bigger scope. I do the same thing when I go back and hunt in Texas...if I'm just hunting in general, I'd use the little stalker type rifle, if I'm in a box stand looking over a sendero/beanfield/food plot, I like the heavier rifle. Just me, but I am "weird", I admit, ha. I just enjoy the hunt better if I can match the right rifle with the terrain. I once tried a 1x4 in Texas,on a Ruger UL .308, and it was fine in the woods, but out on a pipeline or even in some of the woods it was poor for picking out horns. I liked the 3x9 but when I tried a VX-2 2x7 , again, on a light sporter, it seemed to me to be the best of both worlds. I love my 1.5x5 V-3 on my Whelen AI for elk or anything I would hunt with that particular rifle. I am blessed in that I have several rifles to choose from, plus, I find if I diversify, I can justify the expense of it all. I am so "into it" that at times I have to watch myself or I end up spending too much time on my hobby ( therapy!) that I can neglect my ministering...bad, not prudent! (y)
 
I got the 2x7 mounted, loaded up some 130NP blems over H Superformance. I found some data over on Ammoguide.com and I will work up to 58.5gr slowly. In a 24" barrel, this gave over 3200fps w/130NP! wow. I think am going to work on the 130s and the 150s first. My 270 BAR really liked the old Winchester 140 Failsafe, so I think I will try the 140BT & 140 AB in it later. Seems "normal" to work up a good 130NP load in a .270 anyhow! :)
 
Preacher, one thing about today's scopes is that you can buy 5x or 6x magnification scopes and cover a lot of territory. My three most accurate rifles have 3-15x42 or 2.5-10x42 scopes on them, plus I have shot 1-1/2 inch groups (or smaller) with all three of them at 300 yards at the range.

Despite that, I seldom shoot anything at over about 350 yards. Shooting at game is a totally different proposition. Too many variables with mirage and wind et cetera. I want to cleanly kill anything that I shoot at?
 
I was able to get out this morning and shoot the 150 Partition Loads I have to start. I wasn't shooting too good but the day wasn't a total waste and I got a good feel of what kind of velocity I can expect from the 22" barrel. I guess I was too anxious to get out.
All the groups were fired with new Winchester brass, Federal primer, with an oal of 3.330.
First group was with 58.5gr of Reloder 22 and yielded a avg velocity of 2975 fps.

This is 59gr of IMR 7828ssc with an average velocity of 2984 fps.

This group is 59.5 gr of Norma MRP with an average velocity of 3029 fps. This load had a standard deviation of 13.6. The upper group is the MRP the lower group is the 130 Partition with H 4350.

None of the groups were outstanding but they show some promise. I'm gonna try them again with so tweaking.
All the little holes in the middle were from my .220 swift.
 
Bruce, all three of them look like they would tighten up some with shortening the OAL a little at a time. Both the RL22 and 7828 loads look like they will respond very well. Great speeds across the board as well.. I'm thinking you'll have something pretty quick if it is shooting like that right outta the gates.

Man, a 150 PT at almost 3K is pretty good stuff.. Makes the old 270 look pretty formidable.. 8)
 
I'm thinkin' (I know thats a dangerous thing to do sometimes) that the 7828 is the best to move forward with. The MRP had some good velocity but the shot to shot variance was high so I'm thinkin (there I go again) its very close to max at 3029 fps. The 7828 had more than enough umph for what I want and it shot reasonably well. It also had only a vary slight variance from shot to shot with a standard deviation of only 6.5. Sooo, I'm gonna reload the 7828 at some varying OALs and see what happens. Of course, I could just back off the MRP a grain or so and see what happens, just thinkin'. I'm thinkin I ended up with too many powders to try with one bullet.
 
I bet if you back them up .010 you'll start snugging them in together. Your 7828 loads look great. Plus, 7828 always seems to be available.
 
yep, that's what I was thinkin. 7828 always being available is a very good point these days.

Bruce, I would have never thought about that a year or two ago, but after seeing the drought we went through and almost always being able to find 7828 it made me think a little.

Looking forward to seeing what it does with a little tuning. Betting it'll be awesome. Talk about a powerful load though. Not much else needed.
 
Generally, Canadian manufactured powders (IMR) and the few Winchester powders manufactured in Florida appear to be more consistently on store shelves in North America. New import rules imposed under the current administration has slowed the importation of European and Australian manufactured powders somewhat. In short, for the purpose Bruce seeks a powder, IMR 7828 and IMR 7828 SSC appear to be a couple of powders worth considering.
 
I've found 7828SSC to just about mirror RL22 in everything I've shot it in. That's a really good place to be in my opinion.
 
Well, my Superformance/130NP trial was a bust. I got 3080fps but 2.5" group. I'm going to try to work up to 55gr IMR 4350 and give R26 a go too. I'm using BR2 primers in WW cases.
 
I'm starting with the 150NBT and R26. I am starting at 56gr and stopping at 61. Hopefully I'll get some good accuracy somewhere around 2900+. I have a 3.41" overall cartridge length, so plenty of room, but not sure which burn rate to use, so playing it safe. I doubt I would get in trouble as R26 is so slow, but hey, why take a chance and bulge the chamber on my Sweetie Pie by being a Doof, ha
 
I had a very nice custom 270 on a pre 64 M70 action,built by Dale Goens. It had a 22" Douglas barrel and gave a bit over 3000 fps (Oehler chronograph) with 58.5 gr H4831 and 150 gr Nosler Partition. This is the old Jack O,Connor load.

The first day I chonographed that load, I also did a couple of 7 Rem Mags with Federal factory ammo and 160 Partitions that gave in the mid-2800's. This surprised their owners who wondered what was up with that!

That same 270 load has variously produced 2900-2950 in a few other 22" 270 barrels,so what we get for velocity will depend on the barrel as they will vary.

The Barnes manual max load of RL25 and the Barnes 130 gr XLC (coated bullet),gave just about 3200 fps from the 22" barrel of a M70 Classic FW. I would expect RL26 to be pretty similar and see no reason that RL26 should not work as well with the heavy 150 gr bullet.

Most factory loads from the 7 Rem Mag do just a bit over 3000 fps with 150 gr bullets. Based on what I've seen on animals with both cartridges, I doubt anyone will have any trouble killing anything up to elk or moose with either load. Maybe this underscores the fact that the biggest advantage of the 7mm magnums over the 270 and 280 is really with bullets of 160 gr and up.At least that's how I always looked at things.

I like how R26 works in my 7mm Rem Mag so far, but I'm using it with a 160. I have seen similar results from factory loads as you mentioned, a bit on the slow side from advertised. I have never had a problem killing anything with factory loads in any rifle, but I have also never shot at game over about 375yds. I'm sure the long range guys could tell a difference way out there. I like a rifle and load that can shoot through a critter from hard angles and I like to match the bullet construction to the size of the game. Of course, it doesn't always work out that way, ha. Thanks for the info!
 
Preacher looks like I double posted. Oops!

I like RL25 in the 7 mags. Soon as I use up what I have I will jump to 26 myself.
