Reloading for 7mm Mauser
Prvi ammo at grafs. 15.59 box 20. Accurate. Fine deer killer too. Great stuff. Free delivery. -
Fired primers not always inert
Kills lots of deer and won a lot of chicken at 100 to 300 meter black powder shoots. -

Fired primers not always inert
Don't labor under the false assumption that fired primers are inert. Not always. Found out today. A fired SP primer made its way from my bench into the lead pot. Melting old bullets for recasting. A typical set up......pot on the reloading bench and a bit of clutter. Along about the... -
Loading the 4570 with slightly slower powders
I need to bag the rear of the rifle and get back out at 100 yards. Would be nice to see a target without my mistakes on the bench contributing to the spread! -
Loading the 4570 with slightly slower powders
Prolly not the most efficient and I could prolly load heavier too but so far the "ack-er-esy" is jes fine! -
Loading the 4570 with slightly slower powders
Some off hand practice at 25 yards. Trigger sure is useable now that it has the rebound removed and polished and the return spring lightened! About here, at 50 yards bench I discovered why things were off and a shot strayed.....I put the M1 Garand leather cheekpiece on the rifle.....makes a... -
Cast Bullet Alloy
20/1 lead/tin. Rifle and muzzleloder. Velocities to 1800 fps without leading and therefore brinnel is ignored. -
Loading the 4570 with slightly slower powders
Earlier, I went with the loading gurus recommendations and vetted out my 45-70 1886 Winchester with slightly slower powder than normally seen in the 4570 published data. With assistance from a pal with a loading program we noted that my chosen pressure limit and velocity range would fall in... -
Loading the 4570 with slightly slower powders
HA! Thanks. Hmmmmm, I can't easily thread the breach of a barrel cause I got no lathe. But I'm working on a way to do it so I can build a Blackhawk Revolving Rifle. Still sperimentin with the 4570 loads. I'm thinkin I want to kick up into the 50s on powder charge and go to mag primers... -
Loading the 4570 with slightly slower powders
Out at the range. Fired 61 rounds. Busted a lot of clays at 50m and 100m plus rang all the steels at 100m and 150. I need a more stable base for my chrono. Getting some very erroneous readings due to instability. For example, a low of 245 fps and another pair high at 1988 and 2460 fps... -
Loading the 4570 with slightly slower powders
Updating information received from another board member with access to quikload...... "It should be going in the neighborhood of 1500 fps and around 21000 psi. But it's only burning around 70% of the powder. Today at 09:41 AM." Goal is 1500 fps to 1700 fps at or below 25K with cleaner burn... -
Loading the 4570 with slightly slower powders
Coming this weekend I hope is the velocity data including Standard Deviation, High, Low and Average Deviation and some trajectory curves I'll be zeroing to. -
Loading the 4570 with slightly slower powders
In getting ready for another weekend bench session with the new 4570 loads, I just had to do something with the trigger on the 1886. It was near 8 lbs and gritty when I got it. Previous work had softened the trigger return spring and reduced that to about 5.5 lbs and gritty. Now it feels... -
Loading the 4570 with slightly slower powders
Good news is I seem to have my chronograph working again. Will have to check it with known velocity ammo but it seems consistent. (It was underwater in a house flood in 2009....seems it just needed some time to dry out and clean the lenses!) But anyway, my 1000 fps 22 caliber pellet gun is... -
Loading the 4570 with slightly slower powders
Back to the loading bench to try some more H380 loads in the 4570 cartridge case! And then, right back out to the range and success. Great accuracy and based on where the bullet hits at 50 and 100, kissing 1700 fps with that soft 405g slug. No leading. About as much recoil as I want to deal... -
Loading the 4570 with slightly slower powders
A fifth triple was sent down range. 45 grains of H380 powder, middle of the road on the published Varget data set for the 405g lead bullet. Cases miked and inspected at each firing before loading the next shot. Recoil is about the same and I avoid crowding the scope for this set..... Extraction... -
Loading the 4570 with slightly slower powders
Well, no Kabooms. Though I was equipped with ballistic eye pro, double lenses, ear plugs and a strong rifle. Very satisfying accuracy potential and very little unburned powder in the bore or cases, even less residue as the charge weights increased. My results were as follows. Yours may differ... -
Loading the 4570 with slightly slower powders
This here is the article that sparked the quest...... http://plainsmanscabin.yuku.com/topic/4589# Oh yeah, rifle being tested is a rather nice 1886 Miroku Winchester 45-70 lever action, scoped of course! My range of velocities with the selected loads should be from about 1100ish FPS up to... -
45/70 loads
Heres some with lead bullets i use in my 4570s. 405g Lee Flat Point/hollow base - 63g Goex fff, Fed 215 LRM primer 405g Lee Flat Point/hollow base - 27.2g Accurate XMP 5744, Fed 215 primer, 1415 fps 220g Round Nose lead (seated w/nose flush with mouth of case) - 7g Unique
