Can anyone advise starting data for V V N310 pdr for the 45 ACP 185 and/ or 38 spec 148 WC? Would also be interested in any info regarding which bushings to use. i.e. converting from Bullseye to N310. I currently use 4.4 BE for the 45ACP w/ a 160 gr & 2.9 for the 38 spec w/a 148 gr.
Have exp'd lot to lot variation in bullseye recently. I have used BE since 1970 and this was never an issue in the past. I have also encountered pdr bridging when left idle for a short period of time (2 to 2.5 hrs). Shooters using other pdrs tell me they never have this problem. Would be interested in any data and/or comments.
Thanks!

About the Bullseye variations lot to lot: what was your problem? I had a case recently with malfunctions of a previously reliable (3.8 + 185) load in my .45 longslide. Gun was also an extremely reliable weapon. I double checked load weight thrown by my measure, cleaned gun scrupulously, and still had problems.

Excuse the delay in response. Hadn't checked this part of the forum lately. I use, and 75-100 shooters in my area have used the following load since around 1980. 4.2 Bullseye w/ a 160 gr SWC in 45 1911's w/ slide mounted dots. These guys are all Bullseye shooters & shoot a lot.
Of the initial loads from a new 4# can of BE (100 rd trial run) 2 of the 1st 20 cycled. Reliability came with 4.5 gr. The loads are very smoky w/ a pungeunt odor frequently commented on by other shooters. It was so noticeable I checked the clean brass for a sawdust/trash spill.
Alliant was most helpful. I am totally ignorant of pdr & reloading & that I & the other shooters mentioned prev are using an inadequate pdr chg & shouldn't expect it to work. Also, a .3 gr variation in lots is within their spec. The strange smell & large amt of smoke is due to an inadequate pdr chg. In the past I have noticed variation in wt to volume (less han.1 gr) but never reliability prolems.
Solution: 3.9 gr Clays w/ the prev mentioned bullet. 3.8 Clays is a bit weak but very accurate in my 2 guns.

2150,
Started using clays some mo ago also. Quite pleased w/ results [no e-mail]@ 50 yds. Am using 3.8 gr w/ the 160 gr saeco 45acp. Very mild and accurate. For sustained fire I use 3.85 or 3.9 to ensure cycling. Not a viable pdr for the 38 tho. When reliable functioning was achieved, 2.5 gr, the cases bulge so back to BE for the .38.
I hear a lot of talk about "cleaner than Bullseye" but find a hard buildup when the gun is stripped for cleaning. I always clean before a match unless shooting them back to back so the cleaner business is meaningless.

2150....Surprisingly my results, cal wise were the opposite. 2.5 is listed as max for the 38 wc by hodgdon. I did consididerable developemnt in both cals ( 38 & 45) starting quite low in pdr chg. 2.5 was found to be reliable. I was loading 60 rds at a time. I then loaded approx 300 & upon shooting the 1st 2 strings found the cases bulged in the unsupported area of the case. The gun is a colt 38 conv w/ slide mt'd UD. Development was done using nickel cases & the prod run was (mixed) brass. Am using it in rev w/ no prob. Went back to BE in the 38 auto. With the 45 I started [no e-mail]@ 3.6 & went as high as 4.2. The bullet is 160 gr, apparently at the other end of the weight range from yours & prob accounting for most of the variation in results(?). I'm not familiar w/ the H&G 78. What is the weight? The 160 is saeco's version of the H&G 242s (165) which I cast more of than I care to remember until getting (sev of us) a contract for bulk casting w/ the saeco. One of the very good shooters in Ohio is using 4.15 w/ the 160 recently dropping the chg from 4.2 to lower recoil. Although your results are discouraging I would suggest dropping the chg to around 3.8 or so and seeing if the results are satisfactory. In the case you're working on a ball load or need power you prob are taking the best course in abandoning clays. Am also curious about the exp of others.
Thanks for the info!
