I just bought a 26" 264 win, I was wondering what is the best combo for me to get 3200 fps with a 140 grn bullet, it seems like all the load data out there is a tad mild. I am working with ramshot magnum, haven't measured it yet, will this do the trick of will it take some RL25 in times when one needs a rifle, he tends to need it very badly.....PHC | ||

Considering that 3100f/s was possible with powders such as H870 & H4831, 3200f/s should be achievable with current powders. Quickload says 3151 is easily achievable with Ramshot Magnum and Sierra's 140gr HPBT, and it's a load that stays within the prescribed pressure limits. | |||

Cummins RL25 will be an excellent powder . I would suggest you exercise extreme caution as you will likely go from normal pressure to excessive pressure very quickly. I would suggest you work up max loads with H1000 and Retumbo first (single base powders). H1000 should be a little faster and Retumbo should be a little slower than RL25. Then try the RL25. Hope that helps. | |||

I did it with the 140gr a-max and RL22 from a 6.5-06AI  needless to say primer pockets were "generous" after that.Difficulty is inevitable Misery is optional | |||

Gee... and I was gonna suggest PETN  Seriously though... the propellants you mentioned MIGHT do it but proceed with extreem caution. Frankly if you want to do 3200fps with 140's from a 264winchester? The EASIEST way to do it is to trade your 264WinMag in on an identical rifle in 7mmRemMag. a 7mmMag will drive 140's to better than 3300fps from a 26" tube (real chrono'ed results) I've personally driven 120's to just a tick under 3600fps from a 7mmMag... until he looked at the chronograph display my brother was so fuggin' proud of his 257wby  (Now if only Nosler would make a 120gr 7mm Partition)the 7mmMag runs into the same problem with 160's that the 264 does with 140's, the discontinuation of H870. Just remember that sales of the 264win (introduced in 1958-59) just about died when the 7mmRemMag was introduced in 1962. AD If I provoke you into thinking then I've done my good deed for the day!

Maybe but the resurgence of interrest in the 264WM is likely due to the new powders and steels available today...I just ordered one myself and it is being put together by PacNor for me...for me the ballistic coefficient alone is worth the truouble... | |||

the 7mag will shove 140's faster however those bullets have a much lower BC than the 140 berger VLD's I am going to use, everyone says 3200 should be no problemo from a 26" barrel, if that is the case the 7mag CANNOT match the 264 for what I want it to do, and that is an extreme range coyote rifle and maybe a long range deer gun, I looked hard at the 7mag for what I wanted to do, running all the numbers I still chose the 264 win mag, its easy to see why the 7mag is more popular, its a more flexable round offers almost the long range capabilities, and if big game was a bigger purpose for this gun, I would have chosen the 7 mag in times when one needs a rifle, he tends to need it very badly.....PHC | |||

In an article in the February 2005 issue of Handloader magazine, John Barsness achieved 3240fps from his 26" pre-64 Model 70 Westerner using 69.0 grs. of Magnum and a Speer 140 gr. bullet. Magpro also exceeded 3200 fps, and Retumbo got to 3171 fps. RL25 and MRP2 both exceeded 3100 fps. | |||

Every powder I've heard mentioned so far is too fast for optimum velocities with a 140 in a .264. Of commercially available powders, try AA 8700 or Hodgdon US 869. Surplus WC 872 is my favorite. Retumbo, RL-25, IMR 7828, etc. might be fine with bullets of 120-130 grains, but just won't quite cut it with 140s. | |||

Well, maybe my chrono ain't workin', or the barrel is "fast", but I can get 3100 with plain ol' IMR4350, and 3200+ with IMR 7828..both with 140gr Sierra BT's. Haven't tried any of the other "too-fast" powders...didn't need to. | |||

CC; I shoot 140 Hornady sp at 3200 fps from a 24 inch barrel with WC872 surplus 7828 yields decent velocity from the same rifle, same bullet, with 65.0 grs about max in my Win @ 3099 fps In the surplus powders I use WC872, WC 860, T870, T 5020, T 5070 and IMR 5010 in the 264 mag with 140 and 160 gr bullets all are capable of driving a 140 near the 3200 mark in a 24 inch barrel at safe pressures, you shouldn't have any trouble in a 26 inch. All of the above powders are temperature sensitive, can vary greatly in speed from one lot to another and are cheap. In my Speer Manual #8, my first, they show 3300+- with 3 of the listed powders from a 26 inch M70. If you are a reloader, a real reloader that knows how to work up a load, then your 3200 is a cat's sneeze. The first 264 Win Mag was brought into our family in 1971(37 years ago) my little brother still has it and it shoots just fine. Oh, one of the powders that shows 3267fps for a max load is 4831-Speer#8 | |||

where do you buy surplus powders?? also what was the start min and max charge amounts for the 4831 in speer #8?? I would assume that is for the old 4831 which is a little slower burning than the current h4831 in times when one needs a rifle, he tends to need it very badly.....PHC | |||

GI Brass- Pat's Reloading-Hi Tech Ammunition, look in SGN under reloading components 4831- 140 Speer sp 60-64.0 You assume right 4831 had no H or I because IMR didn't come out with their version until 1971 IIRC, although Bruce Hodgdon was the supplier the drums were marked SURPLUS 4831 As for the new H4831 being faster, you couldn't prove it by me. | |||

This is taken from Hodgdon Data Manual#25 H4831 Newly Manufactured "Here is a new batch of the original 4831, the most popular of all powders.Use same loading data as our original surplus powder." | |||

Nope, nothing wrong with your chronograph. And you can always hold the primers in with just a little glue for the second shot out of that brass. To heck with a third loading, you can always buy more brass. | |||

Primers are still tight after 7 loadings, thank you. and the loads are not above max. | |||

i'm using H1000 and retumbo in my .264wsm but accuracy was better around 3100fps 50bmg half inch holes ...... at long range! | |||

update: I have been getting close to the target with H4831 it is producing the better groups however the velocity levels are a little spikey. H1000 is getting the job done speed wise with decent velocity spreads, the groups aren't quite as tight, so I think I am gonna play more with h1000 and play with the seating depths in times when one needs a rifle, he tends to need it very badly.....PHC | |||

I see no sense in any of this at all. WHY does it have to go so fast if 3100 would give better accuracy? Is not accuracy the first consideration? When working loads with any powder there is a sweet spot where a small addition will start to open groups. Why not shoot the sweet spot? To hunt for speed without accuracy is out of the realm of my thinking. What do you gain with 50 to 100 fps? | |||

I know it's not the same calibre but I am getting a genuine average 2905fps with 140 grain Hornady Interlock using 56.8gns H4831SC in my 23.5" barrel BRNO .270". So that may at least give you a starting idea. I would guess your extra 2" of barrel will add up t 100fps. | |||

I run 2900 with 140 accubonds out of my 22" 270 win, the trouble is these bullets are no where near as sleek as the 140 grn match bullets out there for the 264. whats really weird is in all my testing with this gun, I have been shooting 3 shot groups of each load, today I had 3 loads with 6 shots, so 2 groups for each load, after running through the 3 different loads, next up was running through the loads again, I let the barrel cool about 10 mins between groups, each second round test showed a considerable increase in velocity. must be that very small amount of extra heat in the barrel or something in times when one needs a rifle, he tends to need it very badly.....PHC | |||
