Xtreme bullets need advise.

Use the data for 115 gr LRN on the Hodgdon site. Start at the low end and work up a load that works for you.

I'd start off slightly below at ~4.3-4.5 and work up. I ended up around 4.4-4.6 and cycles fine in my Glock

Thanks. I’ll check it out. I’ll be using my sig 226 p239 and M&p 9 2.0 all of which eat ammo Like it’s going out of style and are not too picky what I give it.

IMHO with that load above 4.7 being starting and 5.1 max 4.5 or 4.6 would be easy 4.7 would still be very safe not even getting close to +p

If you are just using starting loads Ive had luck with lead and FMJ data. Its when you push it harder that you gotta be careful.

Actually Xtreme now has a suggested load data booklet for all their product line but only lists 3 powders per bullet. The one closest to the same burn rate as HP38/WIN231 shows 4.5-4.6gn I think if I remember correct with a col of 1.150
I am VERY CLOSE (4.7-.8 and 1.157-.158) with those numbers and comfortable with results in all my firearms from SIG 938 to SIG 365 and then up to Colt Gold Cup National Match. With the longer COL I'm thinking it's not getting to much pressure. Complete powder burn and very little discolor on the brass. Crimp is light (.378-9).

for plated bullets, I just hard cast numbers for the same weight and shape and go slow.

I set at 4.9 gr (1 gr over the Min), COL = 1.115" ( 10 thousandth less) any brass plated bullet (include Xtreme). Couple thousands rds, on several difference 9m pistols, everything bang OK

short answer, yeah I see that is has already basically been answered but I'm bored and day drinking so I'm going to answer it again... for plated bullets the general consensus is to use cast bullet data, while you can run plated a little bit hotter than cast the published data for cast is a good place to start - and by published I am referring to the Lyman cast book

beer on an empty stomach... Lyman makes a separate book specific for cast loads, far more extensive & in depth than the standard book

I don't shoot plated, but ya...use cast data. Cast tends to provide greater velocity for a given powder charge and I'd think plated follows suit. So using jacketed data (larger charge) you can over drive the plated bullets.

Ive loaded 1000s of extreme 115 rns over 4.3 grains of 231 and hp38. Run fine in all of my 9mm pistols and rifles. Extremes should be loaded to cast numbers.

Well, that can end up one of 2 ways.... I'll hope for the better of the two for you

Plated 115g Berry's round nose, 4.6g HP38, OAL 1.125", yielded 1100 fps from a Sig P226. Cycled fine in the P226 and matched most factory ammo in velocity. Used the same load in a Glock and had some brass to face ejection problems. Upped the load to 4.8g HP38 and no more ejection problems in the Glock. Out of the Sig, load measured 1134 fps. Now my standard load.
