I often see request on which wad to use or no wad or .030 or .060 veggie for best accuracy results. Truth is only your barrel will tell you & many results are similar but there are surprise's. you can also read extensive article's but it is based on a small samples also as is mine but thought I would share some results this last sunday on my brux 1/20" twist 28'' barrel.
the targets posted are not pretty as I did not intend or anticipate results to be posted but thought afterward this might be beneficial to some.
the 1/20twist/brux past history with 325gn bullets with h4198 powder. this barrel/ gun is what i call ky challenge material & have a lot of experience with changing wads,no wads & etc to achieve what i believe the maximum potential of accuracy out of this barrel jmho.
this barrel always responded much better with a wool wad(WW) for best accuracy & sd/es readings across the board for approx. 3yrs.
SO TODAYS TEST since winds are 22 to 32mph gust(L<R) i was going to simply test for potential wad difference's changing to I3031/325gn(upper node) bullet paying special attention to fps readings & group size even though not in the best of weather elements. the wind was consistent cycling & i tried to pull the trigger around 25mph & at the same time with cloud cover above for best readings on my cheap chrony.
i wanted to see if different powder/node 90.0 & 91.5gns/325 would make any difference in no wad or wad preference- the answer was no...here are some pic's all shot at 200yds approx. 2 week old results no wad fps were not recorded but remember approx. 40fps difference between all NW shots 
sunday 90.0 v=veggie wad. 2873,17 fps-2shots 
91.5 V 2795,2839fps-2shots 
90.0W-Wool wad ( circled) 2812,09,11 3 shots/added 3rd shot just to make sure this was not a fluke//3 shot 1"grp@200yds//// 3 ES 
so changing powders did not change what this barrel wanted as far as accuracy as far as no wad,veggei or wool wad.
i do not own a lab radar yet but bullet impacts on target corresponded with fps readings where i would expect the poi per readings.

Nice report Deadeye, what wind drift were you experiencing at 200yds with the 325's..? It looks like 4 to 5"...

Good report Jeff. Shooting ain't too shabby for the conditions either! Shooters have to understand that what works for one person in THEIR barrel/twist rate/dimension/ignition system will not necessarily work the same in another rifle with different parameters! In my recent post I found a number of powders and combinations all produced good accuracy with no wad...............add a veggie wad?.........accuracy went to heck! Maybe a wool wad would have shown different results? (I pretty much do not keep them in my box or would have tried them) For me, wool and veggies have generally shot the same and veggies are cheaper!  |

It looks like 4 to 5"... that would be close, I reinstalled scope after re-bedding some lead into the stock so a exact zero was not established however I dialed approx. 4.5" to the right after 1st 2 shot group to get out of the worst clutter on the board & the move proved to be spot on since this scope tracks well in 1/10 mil dialing. |

Richard I agree & have experienced the same no difference in wads in other guns but this definitely likes wool for some reason.
the other bench gun nickel girl never have tried wads but it will be interesting to add some down the line just to see what effect it has on the accuracy in that gun. es usually 12fps & under NW.
this pic looks calm but the tarp needed just to load,no way I could have loaded without a windbreak.

Nice shooting Jeff. I plan to shoot some groups tomorrow with a wool wad to see if it makes my groups more consistent. I have veggies also but to me the wool wads are easier to load.

Does your realworld doping matchup to the BC of the 325AM..? Is BC accurately used to calculate wind drift..? 4 to 5 inches deflection in 25-30mph @ 200yds is not much at all imo... |

allan,yes they are close. I believe kyle has averaged his published bc over a broad spectrum of distance's & per bullet drops much like applied ballistics program so we can assured to be in the ball park out long.

Lubed wads for me. Have had some bullets easy loading when not using wad tumble, this with 75 gr. I4198. Same bullets sized the same with wad never have tumbled and this is one finger loading so it is very light loading pressure.

Tuesday at the range I didn't try wad vs without but did try shooting without a wad with different bullets.
This was with a sav-pac with lukes breach plug.
Just wanted to see if they would all fire without the wad because my new rem-shilin shot so good without the wads.I had tried a group with and without using 300 sst's in it before and both shot about the same.
In the savage I tried the 250 sst first all shot without a miss fire,next went with the 225 sst and all of them shot well.
Next was the (452 ) 200 sst.Loaded the powder and put the first bullet in and dang it slide all the way down the barrel,I had sized these a long time ago and took for granted they were the right size.
Well pushed down hard with the ram rod.I thought this was going to end the day for me if the bullet didn't exit the barrel because I was going to have to take out the breech plug and empty the powder.
I have a threaded pvc tube to do this with without getting the powder all in the chamber using the savage breech plug,since this was lukes plug I didn't have one.
Danged if it didn't fire and even hit the target.Shot the next 2 which were the same way and they both fired.Next was going to be the 230 Hap bullets but was out of time.Will try the wad vs without later
Richard is putting a break on this rifle can't wait to try it out.
