---Hi guys, new here and fairly new to reloading ( been reloading 45 acp for a while). Just starting to load some 147 gr MC REM and 147 gr JHP REM don't see recipes in Lyman. Using 231, any help would be greatly appreciated.
Thanks
You're right. My mistake. WSF but not WST. Should have put my glasses on.They are improved heel radius. I have found specs for WSF but not WST -which I have some of.
I’ll second this - for lower velocity loads 231 will work just fine. For higher velocity loads, you should choose a slower powder. If you have a chrono or have access to one it would help but is not necessary. Use published data for 231, start low and work up to a functioning load. Determine your max and working COL first!!! Good luck.Fast powders are excellent for target/plinking ammo with 147's.
I use(d) 7625, Bullseye and W231 with my 147's including the Rem 147 'match'.
Light recoil, light report, v-good accuracy.
Don't let the theorists dissuade you from trying 147's with W231, it's an excellent combination (if you actually try it).
Hi, I am shooting CZ's, SP01 Shadow and a P-01. I'm shooting 147 XTP which is cycling well and very accurate. Can't find info on the Remington 147 JHP's - they have a round boat tail bottom/base and I'm wondering if that affects the pressure by going deeper in the case?Welcome Aboard !
• Be aware that if your gun has a Match Barrel or is a CZ, striker Springfield, or other tight chambered pistol, then not every 147gr bullet offered for sale can be loaded for your gun. That makes 147gr a poor starting choice for a new reloader.
• WST and W231 are not generally shown for 147gr bullets because heavier bullets generally like slower powders. The loading manuals are showing what is preferred by the general population of shooters. Those faster powders can be used, but it's a specialty load generally reserved for competition, not general plinking. And too, the load range will be very narrow. Something like 0.3 to 0.5gr instead of the loads listed in your manual that are 0.8 to 1.5gr. That being the case, most of the people using those specialty loads 1) have generally been loading long enough to greatly refine their load process, 2) have lots of experience with their powder measures, and 3) are generally using high accuracy equipment. So again, your powder/bullet pairing is less than optimal.
► You'd be better advised to start with a 124gr bullet and W231. That's a classic pairing that any pistol can accept, and the load range is super wide so that beginner errors don't mean much. The likelihood of trouble in one or both of these areas is a genuine reality, so I'm just reporting where your education hurdles and safety limits lie.
You may be suffering under the false impression that all 9mm guns are made alike. They are not. There are HUGE variations in auto pistol chamber dimensions between brands. We'd really need to know your exact bullet and exact make/model gun to take you any further.
Hope this helps.

Some heavier bullet profiles include a tapered base to better fit the 9mm tapered case. That way there’s less of a bulge or wasp waist. The question really is one of seating depth when compared to published data. Hodgdon online has an XTP at 1.100” COL. If you know the XTP bullet OAL, you can calculate the seating depth and compare that to your REM 147. That is if you’ve determined your max and working COL for your guns. And yes, less free space in the case will mean an increase in pressure, so you’d need to reduce the starting powder amount. Have you determined working COL for the REM 147’s?Can't find info on the Remington 147 JHP's - they have a round boat tail bottom/base and I'm wondering if that affects the pressure by going deeper in the case?
Volume inside the case and under the bullet is only half of the equation. So the answer to your question is "No". Bullet seating depth by itself does not create chamber pressure.Hi, I am shooting CZ's, SP01 Shadow and a P01. I'm shooting 147 XTP which is cycling well and very accurate.

Neither. I'm talking about the pure physical barriers of cartridge building.RJ - in your first comment, are you talking about bullet diameter or bullet length in relation to powder? I'm having a little trouble following that.
Neither. I'm talking about the pure physical barriers of cartridge building.
► The way the bullet interfaces with the barrel determines the Max OAL. That's a physical barrier on the maximum cartridge length.
► But the longer 147gr bullet can only be seated so deeply before it runs into the thickening cartridge case wall. That's a physical barrier on the minimum cartridge length.
Some brands of pistols with generous freebore never see this issue. Some brands of pistols with short freebore see this all the time. It is totally dependent upon the brand of bullet, the brand of barrel, and the brand of brass... and how the 3 of them interplay. There are wide variations in all 3, so only the reloader will know (or sadly discover).
Interesting. At one time, 147 grain was my favorite, and I loaded a lot of them in jacketed, plated, and lead. I can't say I ever ran into this problem. I own several Springfields with match barrels, Kahrs, and Sigs. The only issue I ever had was a feed issue with a Kahr. I moved away from 147 because I could find no benefit from running them and so went to 124s.
They are improved heel radius.
