Could I build a .33 cal sml for recreational plinking? The 338 is familiar to me after helping with my friends .338 Edge build. 80grs of H4831 pushed the 250gr Elite Hunter around 2680fps. I know it's not legal to hunt deer with that small of projectile in TN, I just want a toy.

I do not see any reason that it would not work. I have read about 6.5mm ( 26 cal) in SML.

I will work, but the smaller you go the harder it gets. Jeff

It can be done but you are into the area of specialized everything. If you don't have your own equipment to make accessories the cost of experimenting can be a downer.

Seems like someone on here even had a .257 Swinglock at
one time which could be loaded up to .257 Weatherby
loads.
Does Tennessee have a rifle season? Some states allow
ML's of smaller calibers in CF seasons as long as the
required fpe is there.

You have to remember the hotrod cartridges are really pushing the limits. The load you mentioned (250gr@2700) is a lighter one for that cartridge but still probly has a chamber pressure around in the high 50s low 60s ksi. One thing we have learned is as chamber pressures increase so does wear and tear on the vent. As was shown in another thread it basicly takes X amount of powder to get a bullet of Y amount of wieght to go a certain speed. When you decrease the bullet/bore diameter the pressure goes up.
I always thought a cheap plinker would be a .358". You could use cheap sized .357 pistol bullets smoothform to teach kids ML basics or just plink. If you wanted to get more serious you could fullform .358 rifle bullets. Maybe even go after tree rats using a MMP .36 cal sabot with .32 or .30 cal pistol bullet.

Dougs gun was 6.5 by Swinglock But like Meyers129 stated everything has to be made specifically for it.

Not sure on the rifle season (muzzle loader rules). I know the only caliber mentioned on the MZ is .36 or larger. I think rifle is Petty much any center fire. Hillbill??? lol what you think?

Has anyone got a boattail bullet to fly right from a sml?

Thanks for the idea Mid-Tn.....................I am going to take some 300 gr. SST' and cut a boat tail on them and see what happens!

In rifle season you could pretty much use anything you want, I honestly think Tn would let you deer hunt with a pocket knife tied on the end of a stick if they thought it would sell more licenses.. self funded DNRs are terrible, its all about citations written, fines paid and license sales.
the good of the animal herd went the way of the grouse years ago....

Or this.....................Barnes 290 TEZ Yes, did it in the lathe! I will probably only shoot one of each to see what they do before destroying any more   |

I personally have never had any luck with boattails in a SML but I have never shot them full formed and that could make a difference. Smooth formed and in sabots were not good, I had keyholing at times.

Since I am not full forming yet jims, I will let you know next week how they fare. My plan is to shoot one uncut and one cut.

Barnes TMZ's are boat tails. They shoot just fine sabotless |

The .416 would be my pic of the high bc bullets to shoot. I got to thinking tonight about building the kids a sml and wait on some more of y'alls testing before jumping in. Need to take my 700Ml and send it to Hillbill and let him craft me a short,light weight rig for my kids. I will be getting a hold of Luke in a couple days to stock up on .458 goods. Trying to decide on a brake also  |

Richard, do you have a full form to test .458s also?

Omega.......My mistake~!  I have the "TEZ's" (flat base) not the TMZ's,,,,,,,,,,you are right. Somehow I did not realize there was a boattail version of the TEZ!................Well, for me it will be new. Chad...............The Barnes bullets are too "dear" to waste cutting up if they do not work. I figure if I shoot one as a flat base T-EZ and the other as a boattail T-MZ I should have an idea whether or not I should proceed with further testing at another time. Mid_Tn............No I do not have a full form die at this time but am hoping to get one in the future. I will definitely re-visit them if and when I get it. My plan would be to heavily knurl them and then run thru the FF die. I really do not think the boattail will be more accurate but its BC is higher. So, if they both did shoot equally as accurate, then the T-MZ would be the preferred bullet. I would definitely trade the small difference in BC for much better accuracy! A click of the scope can compensate for that. Barnes list the BC on the 290 T-MZ boattail @ .241 290 T-EZ flat base @ .223 Richard |

Richard, I'm not a Barnes fan, yeah I'm goofy like that , however if you could maybe see about a group of the 300 SST that would be something I would be interested in. Another question, do you think the small amount cut off the SST is enough to make a difference in the BC or would you have to go more to make it worth while? |

Post by Richard on Jan 30, 2015 21:52:46 GMT -5
Chad.............Yes, I could prep a few more of the SST's. I weighted the cut bullet and it only lost 1.5 gr so I don't think that would effect BC very much. The Barnes lost 5 gr. I have to watch removing too much on the SST's or risk cutting into the core.

Richard I thought about that also when cutting the edge off cutting into the core. Would it make much difference even if you did? Suppose if you did the jacket could start to separate from the core when you shot.?.?.

I have actually machined the base completely off.............right to the lead core and got some very good results. My thought was that it would help obturation. It was just a PITA to do it! For hunting purposes, it might not be the best thing for a bullet staying together? Shooting something like the normal whitetail in the boiler room it should not really matter. For pure accuracy, I don't think you can beat the flat base bullet. Most all short range benchrest shooters use flat base bullets. It is not until you start stretching out the distance that the benefits of higher BC's (which the boattail provides) takes over. The flat base bullets tends to be stable right out of the muzzle whereas the boattail/VLD type bullet may not? Its not completely "cut in stone" but that is the general thought.
In the ML fraternity boattail bullets and sabots have been a NO NO since they tend to bore thru the sabot. Now that we are shooting a lot of sabot less, they very well might work? The question is, do they need to be FF sized? Will they work with smooth sizing?..........with or without a wad?...........veggie or wool? Maybe I can find out?
Here again, at the distances most deer are shot, does the means justify the end?
