John Henry Quick Posted October 30, 2017 Share Posted October 30, 2017 I'm curious if .38 Special/.357 Magnum cases suffer from blowby when shooting black powder like .45 Colt does, or do the cases seal the chamber more easily? I know someone will want to tell me about annealing brass, but I'm asking about the average .38 case without annealing. Thanks! Link to comment Share on other sites More sharing options...
Marauder SASS #13056 Posted October 30, 2017 Share Posted October 30, 2017 The do not have as much blow-back as the 45. Partly because they are smaller and the pressure curves are different. A good crimp helps a lot, of course. Most folks don't bother annealing the 38's. Link to comment Share on other sites More sharing options...
Sedalia Dave Posted October 30, 2017 Share Posted October 30, 2017 I experience very little if any blowby shooting .38 specials. I shoot 125 gr LTC bullets with the case filled to just below the base of the bullet with FFFg APP. I do not anneal the cases. Link to comment Share on other sites More sharing options...
J-BAR #18287 Posted October 30, 2017 Share Posted October 30, 2017 What little blowback I get is rendered inconsequential by spritzing the rifle carrier with Ballistol about every 3rd stage. Revolvers never need nothin’! Link to comment Share on other sites More sharing options...
I. M. Crossdraw, SASS# 8321 Posted October 30, 2017 Share Posted October 30, 2017 No problem with blowback here. I don't anneal cases. A good crimp and I'm good to go. I shoot real BP, too. Link to comment Share on other sites More sharing options...
Jefro, SASS#69420 Posted October 30, 2017 Share Posted October 30, 2017 Not a problem with 38, a good BL bullet carries plenty of lube. Heather and I share guns when she wants to shoot BP, (allot lately) so that's 12 stages on those guns. Depending on humidity I may wipe the cylinder face with a couple of drops of mule snot (Murphy's mix with Ballistol) after third stage. Good Luck Link to comment Share on other sites More sharing options...
The Original Lumpy Gritz Posted October 30, 2017 Share Posted October 30, 2017 Load it with 3F, and enjoy. OLG Link to comment Share on other sites More sharing options...
El Hombre Posted October 30, 2017 Share Posted October 30, 2017 Nope no real problem in my 38's. Still get the old carbon burn but a bit of lanolin spray every third stage fixes that up. Same with my revolvers Link to comment Share on other sites More sharing options...
Diamond Curly SASS#57086 Posted October 30, 2017 Share Posted October 30, 2017 I have never had an issue with blowback from 38’s using 3F and a good crimp. Fun round to shoot with black. Shoot C&B in revolvers in both 36 and 44 so not familiar with 38’s in revolvers. Link to comment Share on other sites More sharing options...

Amarillo Rattler Posted October 30, 2017 Share Posted October 30, 2017 I shoot BP 38s in light wind conditions and BP 44-40s in higher wind conditions. The 38 blow back is slight, wipe the cylinder faces and rifle receiver area ever other stage with baby wipes. 44-40 is good for all day. Winchester AA hulls blow back burns the outside of the hull, one shot and in the trash. Fiocchi hulls are good for 3 reloads, trimmed after each load.

Amarillo Rattler I shoot .44-40 with Big Lubes over a full case of 3Fg (well, technically it's 5Fa, but that's a different discussion) and Remington STS hulls with 3Fg/5Fa in Frontiersman. The .38 (if I get it) is going to be my backup rifle. Link to comment Share on other sites More sharing options...
Cholla Bob Posted October 30, 2017 Share Posted October 30, 2017 Fill em up with 3F and throw a snakebite big lube boolit in with a good tight crimp and you will be good to go, shoot six stages with no issues Link to comment Share on other sites More sharing options...

Jabez Cowboy,SASS # 50129 Posted October 31, 2017 Share Posted October 31, 2017 I use Goex 3F in both ,,,,,, All my FCD rounds ... My .45 Colt brass is as Clean as my .38 special brass after firing.. The .38 spl. has at least as much blow-by as the .45 Colt when you consider the volume of powder burned .... I feel that properly loaded .45 Colt cartridges don't have a real lot of blow-by ,,, but trying to download the old Girl causes a very dirty gun ... If you want no blow-by shoot .38 WCF ( .38 - 40 ) my FULL case loads of black leave cases cleaner than my smokieless loads I use for In-door shooting in the Winter ..

Major BS Walker Regulator Posted October 31, 2017 Share Posted October 31, 2017 Mr. John Henry, I would expect you would want some blow-by because of your love of cleaning guns. Link to comment Share on other sites More sharing options...

Walker said: Mr. John Henry, I would expect you would want some blow-by because of your love of cleaning guns. I actually do love cleaning my '51 Navies, but not rifles! Since I switched from .45 Colt to .44-40, I've gone from tearing the gun almost completely down after EVERY match to now with my .44-40 I just pull a boresnake through about 5 times and I'm DONE! In the 3 years I've been shooting that .44-40 I've only pulled the side plates off to clean her one time after two years of full-power BP loads and ya know what? She was CLEAN! I already have an extra '51 Navy and an extra shotgun - the .38 Rossi 92 I've got coming is going to be my backup rifle and it's nice to know it'll shoot relatively clean. BTW, I plan to be out there this Sunday if it ain't raining ('m so durn sweet I just might melt). Cya then! Link to comment Share on other sites More sharing options...
Edward R S Canby, SASS#59971 Posted November 1, 2017 Share Posted November 1, 2017 Much depends on the gun. I have a Marlin 1894 that only shoots .38s. It has much blowby. I must lube every other stage to keep it running. I just shot Bordertown with a Marlin shooting .357s. A fellow BP shooter remarked that the receiver was so clean it looked like I was shooting smokeless. Link to comment Share on other sites More sharing options...
