Chambering Force with slugs

[bubblerboy64]

I’ve noticed across the board that there is no force at all to chamber a slug.as compared to a pellet. I don’t know if this has any affect on accuracy but with fire arms we’re used to bullets engaging the rifling and we would set the position of the bullet purposely in the throat of the barrel. When I have been testing with slugs I have the impression that after closing the probe if I was to point the barrel down the slug would slide down the length of the barrel and fall out. 
is this “normal” with slugs? The rest of you experiencing the same?

Depends on what gun. Some EASY while others a REAL MOTHER to load. Yo!

Hey bud, how are you? All is well I hope. Are these questions regarding your RAW or Impact? I had similar thoughts a while back so I did a bunch of measuring of diameters. A .25 caliber Diabolo pellet has a skirt diameter of .256"-.260", sometimes up to .264" and the skirt is very thin so when chambered it just squeezes down to fit the chamber and barrel diameter. I've tested .248", .249", .250", .2503" and .254" slugs and they all chambered effortlessly like you're talking about. There was just a tad bit more resistance with the .254" slugs, not much though. I remember some Rat Snipers a long time ago that would hardly even chamber in my 600mm slug liner, they were tight. Unfortunately, I don't know what Rat Snipers they were or their diameter? As far as the actual diameter of the lands and groves or the diameter of the choke in my FX Impact, I don't know exactly what they are and haven't been able to find out for the .25 cal FX slug liner? Probably proprietary, so it's hush, hush.

Everyone talks about the diameter of the slug having to match the diameter of the barrel exactly for optimal accuracy, I believe that to be true and obviously understand why. However, throughout my slug testing I have experienced some very strange results. I talked about it just yesterday. Some of the most accurate slugs I shoot are .249", however, I've tested lots of .250" slugs that were also very accurate. I then sized them to .249" and .2485" and they still shot very well, hardly any difference. Explain that? I've even shot some slugs sized to .248" that were exceptionally accurate. There are many concepts and beliefs considered to be the norm when shooting pellets and slugs that I'm finding not to be true at all. This is exactly why I always tell people to test everything themselves! I know that you know, slug testing can be absolutely baffling sometimes! Rewarding but baffling! 

Have a great rest of your weekend! Stoti

Hi Kevin . I’m talking about all the guns I’ve tried slugs in. I’m concentrating on the impact which has the new superior liner. Logic which is often wrong or at least mine is would seem to be that a really loose fit might not be ideal. The wind is calming down here and I might get a chance to do a little testing. This impact shoots the JSB 34 pellets so well I’m losing enthusiasm for slugs but since I have about two bajillion of them I almost have to try.

Yeah, I hear you. How many times have I told you I'm done with slug testing? I have really been excited about the .254" slugs that I've started testing because I thought that might be a huge difference. I started testing them and then it got windy and has been windy ever since. Unfortunately, I haven't been able to do much other than the initial testing. The diameter of slugs and the fit in various barrels/liners has been the most perplexing factor in slug testing, period! It just doesn't make any sense. The other thing that I can't figure out is why the dish base and flat base shoot so much better than the hollow base that should theoretically swell or squish down to fit the barrel like a pellet, thus sealing properly and becoming more accurate. I thought it might be because of the seating depth but yesterday I made a seating tool to make sure they were getting seated properly, just past the transfer port. It made no difference. The other thing that confuses me is why the large hollow point slugs shoot better than any of the 2-S hollow points? I've heard from a few other people that have had good luck with the 2-S hollow points but not me, not at any velocity or HS/Reg. combination. I think what has me constantly thinking about this stuff is that there is really no direct correlation that I can find, between all of these factors and accuracy. I've tested a lot of slugs and can tell you which ones shoot the best in my guns. Unfortunately, although I see the similarities in slugs that work and similarities in those that don't, I can't tell you with 100% certainty why some slugs shoot well and others don't. It's a hard one to figure out, that's part of the reason I love these posts and discussions. Right or wrong, it's more stuff to think about. Have a good one my friend!

Does the FX slug liner start off smooth like the pellet liner? I have only dealt with fully rifled barrels for slugs. For me, my best luck is cutting or hoping for a leade that I can feel the slug engage the rifling. But even that doesn’t guarantee accuracy. If I have to force a slug or it has no resistance, I don’t even waste my time anymore. Slugs are weird because we aren’t supposed to be propelling bullets with air. That’s why everything is so sensitive.
