Having problems with this load: 250 gr. FTX with 42 g. vv-110 and mmp high pressure #12. About on a average one out of four shots will detonate. The sabot will blow apart into so many pieces it is hard to find. Otherwise the accuracy is very good. I have reduced the charge to 41.5 and 41 gr. of vv-110 with same results. Not sure what to do next. Do not want to loose this load. It has dropped and flopped every whitetail for the past five years. One more thing is the first shot out of a clean barrel is high and left. Next two or three are on zero.

Brush out the barrel after a blown sabot. Maybe try a different kind sabot, or a different lot # of same sabot. Yours could be old or bad since you have had good luck in the past. Or drop your charge weight lower, 38 or 39 gr n110 is still doing pretty good. Or try a light knurl on your bullet to grab the sabot better. Very few 50 cal smokeless guns I have been around shoot a saboted 45 sst very good, base may be radiused too much. The 325ftx is a different story though. Always done good in all our testing. Good luck.

Good advice already given, you might also try a veggie wad between the powder and sabot to see if it helps from blowing sabots. Never hurts to try...

It's a fiber wad that can aid in sealing and take some of the brunt force of the blast and in some cases imo can help save sabots and even sometimes improve accuracy even in saboted loads. Its worth a try, they are fairly cheap.

Are you using a cool rod or allowing adequate cool down time between shots?
Do you have any harvester smooth blacks to try? I think they are a bit tougher, personally. I've never had and issue with 42gr of N110 and a 250gr bullet with the harvesters.

If it's accurate what difference does the look of the sabot make. I pretty much use the same load but 43 Gr with SST

Oh! Veggie wads! I used them 48 years ago to load shot shells! I think it is worth a try. I also think it is time to look at the inside of my barrel. There may be something missed with cleaning. It is a tight barrel. Loading requires about the same pressure as what I would use to compress the charge.

I have used Harvester sabots in the past but not with this load. The vv-110 has not been available for a few years at least locally. My powder is old but I have never experienced an issue with old powder. It smells fresh to me. I don't know any way to check powder other than smell. Any suggestions?

You could also try the hph 24's. Mine is tight as well, I was shaving plastic off the sabot when loading it.

I have used 24's and 3-pez without issue. They are .002" or more smaller and it will probably make an easier loading. The 12's are tighter and work well with loads I have worked up with 300gr. Sierra fnsp.The Sierras are slightly smaller than other .452". the box indicates .4515". (also mic'ed the same)

Just curios how thick of a wad are ya'll using? I primarily use .060 veggie wads for sabotless .45 shooting. When I shot saboted loads I used .030 veggie wads, it was tried as an experiment and in the particular gun I tried it in, it actually helped my accuracy a bit. Not saying it's the golden standard or a savior but I do believe it can help relieve some of the stress on the sabot. Every gun and load combination is different, so it can never hurt to experiment with things like different sabots and wads, especially if you're having difficulties. (Once you've eliminated the possibilities of things like: too much pressure, rough bore, too tight of a fitting bullet/sabot, etc..) JMO |

I have not tried a veggie wad. I have used them in shot shells many years ago over the charge. They were made of cardboard. I don't recall the thickness but I am sure they were about the same or slightly less than .030". I will have some time next week to shoot in cooler weather. I am interested in sabot-less .45 shooting. There is information on this board about sabot-less loading with .45's. My most repeatable groups come from a cool barrel with only a only a patch through it between shots. The are not the best groups but they are consistent groups. When I shoot cold and clean my first shot will be high and left of my zero. (1.5" to 2") Clean and cold would be the best for bench rest shooting but in the field that will not be the case. Exception is the first shot. I have thought about a zero between the two shots but the next shots are MOA or a bit less providing the sabot does not rupture.
