65-66g H4198 will get a 225g AccuMax into that range with a 209 ignition and a 26’ barrel. 10/53 VV110/H4198 will also. With a modern ignition - start lower. A wool wad is generally necessary as well as sizing the 402 g bullet for a good fit. Being that I was just starting to test with the 225 Pittmans/45 when I got my 2nd 40 and sold my last 10ML2/45PN, I didn’t test any further. A load that really looked promising was 10/60 VV110/2015. Clean and in the 2725’/sec range.
These loads seemed safe but on the upper end for my gun but others?
I posted the previous posts because I think so many new shooters just aren’t aware that sabots are a viable alternative to boresized shooting.
228 @ 2700+ in a sabot. 2 powders I really “liked” (now shoot a 40 and 2 other 40s) were H322 and better yet, 2015. In a 209 rifle, I’d often use 5-10g VV110 (5744 or discontinued 4759) as a duplex and start with about 55g of 322 or 2015 and slowly work up. Sized 225/228, very lightly knurled, HLBS, wool wad. 5/65+/- VV110/2015 was a favorite of mine. My favorite loads have always been 110/2015 for saboted 40/45 loads of 2700’/sec +.. Once again, safe in my rifle but maybe not in others.
VV powders are especially good in smokeless MLers. VV120 w/o a duplex is particularity good as a single powder. Certainly try it if it is available. It was disastrous, performance-wise, when used as a duplex with VV110. Used as single powders, both 110 and 120 have excellent temp/velocity stability; but together, ie 110/120 they were terrible. With a 250 XTP/sabot in a 10 ML2 (50 cal - stock) 10/60 at 80 degrees 2700’/sec, at 0-10 degrees <1900’/sec. In the great freeze of 2002, many of us experienced this phenomenon. That’s when 14/61 VV110/H322 replaced the 10/60 110/120.
Hope you didn’t hold your breath for this answer. Sorry for the delay.
I would not have expected the VV110 and 120 combo to do that but one never knows.
No one did. Each powder alone 45 and 60 respectively was very temp insensitive; however, together, they were a disaster. That 10/60 load was used by so many of us and then the incredible cold came. Below 0F here in Arkansas for over a week and near 0 for about 2-3 weeks. This performance phenomenon was the talk of Doug’s board and a lot of us experienced it.
All of this info is fabulous !!! IF i ever get around to a LW 45 sml for my 700ml this is my planned course i do believe Saboted Primarily . Other states may have different regs than Michigan does i know , which is sml for rifle season and bh209 for muzzy season , sabots allowed in both . Complications !!! Its a big reason why im looking at a LW 45 too for other states that require one , even bore sized . I am a huntin fool !!! Has anybody had any success with a 250 pittman as well or the 240ot fury saboted ?? I have all 3 bullets ....the heavier ones i havent tried yet . Thank you gentlemen !!!

I have stay with 225’s because they will stabilize in my 1-20” twist.
i understand . Im considering a faster twist for that reason . Ive a buddy in Texas that shoots bh209 and Can stabilize them . Its capable of smokeless but thats what he uses for sabots . I dunno why.....yet . Its light like Sews new 40 . Carbon fiber barrel and all with a 1 in 14 but a 45 . He loves it !!! Shoots 275s accurately too full bore . I guess at that bullet weight/rifle weight full bore sml is an attention getter loaded hot . The brake is small !!! A sabot friendly brake IS offered by Harrels Precision in 45 and 50 caliber and helps some with full bore . I have one in a 50 . He planned it for sabots primarily as a spot and stalker . Hogs are taking a beating !!!
