Poor accuracy with cast pellets

[miksatx]

lol hunter mags clears the TP but super super tight going through the choke. Had to take off the handle on the cleaning rod and finish pushing using my weight and the deck floor. The jsb head measured .215 the hunter mag went .217. Wowser !

Then I would try lowering the pot temp some to shrink the fill out.

grabbed my air max dominator scope it. shoots them accurately at a backyard friendly 760 fps. That works for me lol.

Good sharp edges at the bottom of the skirts make all the difference, sitting the pellet on a flat surface (skirt down) will show how well the skirt is filled out with a magnifying glass, if I have pellets with rounded skirt edges they go back in the pot, I'm blessed with good vision so I see all that stuff with my readers and optivisor that I always use for inspection.

Wayne, I bow to the master with "ladle "only! That stuff looks impressive!!!

I would still inspect the barrels... some of the disco .22 barrels were on the large size I have one that is ~.218... also if the leade has a sharp edge that will make them pellet picky depending on how bad it cuts fins in the pellets skirt...then some times there is a burr at the transfer port that needs knocked down...

on the  mutant is it the CZ barrel... might want to check the crown I saw a few complaints a while ago... and on a tight barrel might help to experiment with some different lubes... the CZ barrel could maybe use lapping/fire lapping..?

I have had barrels that shoot great with a couple pellets that had problems that when fixed really helped other pellets do well...

My Mrod .25 hated benji domes... now that it has a leade and not just hard sharp edged rifling... they tie for 2nd just behind the JSB Kings...

but yep slug and inspect barrels to remove those as reasons... but yep some just may not like a certain pellet no matter what you do...

[darkcharisma]

Kirby, I recall OP doesn't have a problem with JSBs. So it's not a barrel problem

[K.O.]

no bud it just means the barrel does not have a prob with the JSB...thinner more collapsible skirts...

My Mrod .25 does .5" at 50 a lot with King 25.4g on a still day... but the sharp edged rifling cut into the skirt with Benji 27.8g producing fins and unequally at that... Benjis were about 2.25 moa...I took a tapered chefs steel to the barrel and now the barrel is almost perfect for the 40g BBT... almost... it is great with Benjis now about .7" ish...

still had a bit of lip that would catch on drive band of the 40g BBT and that caused the short round to cock very slightly in the barrel once or twice in ten shots... could feel it every time it happened... causes fliers out to about .1.25 when they load right they are about .75 when sized to .2495 and .250...

I think I got that last tiny bit of lip when I finished with 800 grit wet/dry and a shaped dowel last time I had it apart... but have been to busy to cast some more up to test... Have a pic of the barrel pre work posted somewhere...will post a link when I find it...

 My Stormrider .177 liked  JSB 10.3 and Sniper Mags only... post work it likes the CPUM and Copper Mags also and some others do well...and it did not need as much work due to less rifling height and rim...

post #2 has some pics...

point is it still can like some pellets tho it needs work... it may not be the prob but is worth taking a look...

Mrod .25 Breech end barrel pics post # 15... Pre leade work....It did well with Cudas and FTT this way also but just did not like the Benji pellets...

Oh forgot the 34g Magnum Hunters are about .75" at 45 ish yards out of my 50 ish fpe .25 Mrod that has the leade work... not quite as well in the other untouched Mrod at about 45 fpe... pins for the skirt are fiddly to get perfect but need to be... have the mold in 2 cavity and Brass...feel that is best for consistent results...

[Wayne52]

I've found that once I've tweaked the pin holders right it then makes disassembly/reassembly adjustment very easy.  When I tighten down the pins I'll do it in a manner where distances on either side of the  screw are equal when it's tight. Most often the pin holder will move a little when tightening down and a person can judge by watching where it'll be tight.

I had terrible accuracy with the NOE .25 Mag pellets. This was the 1-14 twist evaniz barrel. I removed the choke and it improved, but not by much.
I later installed a 1-18 barrel with 10 grooves and lands, and no choke. It shoots them very well. 


I an quite happy that I can now use the pellets as intended.


Kirby, is correct, the lede is very important, as is remaining any burr in the transfer port. Any nick in the head or skirt will play "L" with accuracy!

Sine some guns like the cast pellets, and some don't, I would like to see us set up a system to send our cast to people wanting to test in their guns, without the very real risk to their wallet being chanced on a pellet/barrel combo what won't work.


I have found happiness with the .25's, and now want to try the .22's in the light version. Both in my Maximus, and the SA700 that should be arriving in time for my B'day. I refuse to pay high prices fo rpoellets an shiping! GRRRR!!


Being disabled, and on  a fixed income is well, Double Grrrr!!!


Makes pellets, especially the .25 JSB's a hardship. The cast while recovering the lead is a real boon for me. But leary of risking the moneys on a .22 mold.


No doubt, many are in the same boat. I have sent many bullets and pellets to members. Some worked for them. Some not. Which I guess is the entire point!

I haven't tried the Magnum hunters in my latest .25 but the Hunters shoot really great from it.  I plan on upping the power on this gun in the near future and I'll try the heavy ones in that.  It's a Xisico Sentry which I found out is actually a prototype for the new ones coming out in August or September and don't mark my word but I think they'll be a side lever action.  I also found out there's only 20 like mine here in the US.  I have been offered a bargain price on them when they come in and I'll probably order one of the .22's.  As far as I know they might not even call them a Sentry.

I'm hoping the 217 wadcutter mold comes out soon, my .22 Hunters&Magnum Hunters I like a lot but shooting my .22 pistols (especially the vintage stuff) would more than likely thrive on them.

Once I get around to it I'll be casting magnums likly 23g in .22. First few hundred will likly not so good but I may be able to send some out when I get good at casting.

I'm definitely in about the same boat thou I'm not disabled but on a low fixed income. I love to try some cast pellets just see what they will do. I've been trying to save my lead from my trap as that's seems to be where I do most of my shooting. Don't really hunt except if I see a ground squirrel on my property I will try to kill it but that's it. I have a lot of rabbits around but I leave them alone and LOTS of ravens but they're protected. I can't shoot the sparrows as the wife loves them lol. Just want to target shoot and maybe some silhouette shooting.

I'll just about bet the Smith and Wesson 79G co-2 pistol I am using now would like wad cutters as well,

[miksatx]

Last night I cast up some 217-20 they run from 19.4-19.9 & 20.0- 20.9 separated them into bottles. This morning I grabbed the 19.4 - 19.9 bottle. Loaded up the mutant mags 2-5 shot groups @15yds 2 different fps.

[UlteriorModem]

Odd that the higher fps seems to have grouped better!
