new 45 cal pac nor barrel

[mac111]

Looking for help . I have the new pac nor 45 cal barrel i have put on my savage receiver. it is a 28 inch barrel 1-22 twist. shooting 58 gr or h-4198 with wwad. group ok but not as good as it could be. started shooting with out w wad groups got real tight but started getting sabot failer. using 195 barnes withe blue harvester sabot .noticed with w-wad not really flared at sabot base. with out w-wad flared out good Waite 3 min between shoot also. any ideals?

Unless You live in a cold area wait longer. With out the wad your sabot gets more heat and if the barrel has already started to warm it then it will fail.I use the tan sabots and have never blown one with 200 gr bullet and 62 gr I4198. I tried the blue did not shoot as well. I want to try them again when I have time. My barrel is also real lose as in a a .452 bullet just slides down on its own weight.

If you were groping well what are you calling sabot failure. Missing peddles does not equal failure

[mac111]

Thanks joe21a , im shooting the .40 195 gr bullet in my pac nor 45cal. As far as failure the sabot is totally shreaded . just find pieces. Are the tan sabot you use mmp?

Drop back on your powder charge, the sabots are telling you there's a problem

I had the same problem with my Pac Nor.It shot very good groups with blue harvester sabot and 195 Barnes,but I had to drop back to 56grain in order to get reliability.Sabot failer would cause and occasional bullet to go into the black hole or the bullet would hit the 100 yard backboard key holed.RB suggested I try a different powder.I think it was H322,but don't quote me on that.I have the suggested load wrote down,and I;m going to try it when the time and weather permits.I never tried the brown sabots,but that may be worth taking a look at.Apparently there are some that have been able to shoot higher velocity without any problems with sabots,but I have not.Twister

:)mac,first congrats on your new barrel and as far as you blowing sabot's with 58grs what was your velocity?what was the temps?if your barrel is alittle tight you might only be able to go to 58grs but you might already be at 2600fps.the blue harvestors have alway's been stellar in my guns and i have never had luck with the tan mmps and i never use wads.you have a long barrel which will work nicely with 2015 start at 68grs and work up to 72grs and see what type of numbers you get i bet you will be real close to 2800fps at the upper charges.goodluck

I think the load is a little too hot. You have 3" extra length than many of us and that would make this relatively standard rather hot. I agree that 2015 would be a better choice than 4198.

I have both a .45 cal and a .40 cal pacnor , i
The .45 Cal load i am currently using a Light blue harvestor crush rib sabot and a 200 gr bullet with 80 Grains of 2015,Fed 209A.... shoots 2886 fps and 3/4 inch 3 shot groups out of a 26 in barrel loads really nice and shoots amaxing temps have been from 6 -55 degrees and no problems with ignition or sabot failure


the .40 cal I am using a 170 gr hornady HP Knurled and 70 gr 2015 fed 209 A and it to shoots 3/4 in or under.

[nitro1947]

the lenght of ur barrel maybe is building more pressure due to 28 inches ..might have to go to slower powder or less of the hotter loads

[joe21a]

Mac111; Yes the tan are MMP; I am not sure if the longer barrel would make more pressure, because powder has reached max pressure (in mili sec.) before bullet has left the barrel.

[dwhunter]

Try 62grs. of 2015 that's the ticket in mine.

[mac111]

Daved d Thanks for your repliy . I did shoot again with 2015 started at 68 gr shot then went 2 gr incroments up to 72 gr. 72 gr shot the best being about 1-1/2 appart .all shots 3x each. no sabot failure. tryed 76 gr started having sabot failure.( drilling sabots)

[dave d.]

:)mac your welcome.have fun with your load developement.
