This rifle was built in a very short time just prior to the Helfey Creek Rondy. The lock isn't finished and is in the rough, as-received condition. It is an early Siler and sparks amazingly well - best I've seen so far. I took the single picture at a distance and low resolution as it appears to be very gappy around the lock. The lock panels have to be reduced in height to below the bevels on the sides. Then, the fit wil be about as perfect as can be.
The rifle has a 13 1/8" pull with a 15/16" x 21" Bauska Barrel. Last night, I pulled the plug to check the bore and it appears to have been very nicely lapped - hard to look through at the flurescent lights in my shop. With the wider sight up front, I expect it will be a good grouper and may be a very nice light handy deer rifle and good for moose to about 50-60 yards. It will fit in the truch on the dash, or very handily in a boat or canoe. Much more so than a longrifle. Gary Mummery, who built this rifle, says it was a 'lark' something for a conversation piece. I promptly bought it from him at Rondy. He'd no sooner put his price tag on it on his 'sale' rack, and I removed it to my tent. It has a very nice piece of Walnut, eh.
I tested it on Friday wit the skinny front sight that I couldn't see and best groups at 50 yards were in the 2" range. I'm sure the pistol-type front sight I've just put on it will help in the accuracy department. It may soon have a roundish U notch with a bead front to gvie a peep-sight-type a sight picture. We'll see. I was thinking of putting the "for-sale" .40 swamped Rice barrel on it, an "A" profile that would fit fairly well and look just fine if reduced to about 32", but decided to give the .50 a chance to do it's stuff before changing it, if I ever change it.
Chrono testing was interesting to say the least. Of course, I used the same "lot" of slow GOEX I used int he .40, but kept my testing to 2F due to the barerl's short length. I figure it needs all the speed it can muster within my [narrow' recoil limit due to shoulder problems.
: I used LHV lube for the test as this is purely a hunting rifle. Patches were .020" denim, the same ones I use with .400" balls in the .40. I used Speer swaged .495" balls for my testing.
80gr. 3F load coombination as noted above.
1/. 1,446
2/. 1,463
3/. 1,477
4/. 1,462
5/. 1,491 spread 46fps Av - 1,468fps
90gr. 3F same load combo
1/. 1,583
2/. 1,588
3/. 1,545
4/. 1,521
5/. 1,527 spread 67fps - Av - 1,553 - recoil at this point was about all my shoulder will handle for continuous shooting and actually shot the best, accuracy wise.
100gr. 3F same load combo
1/. 1,624
2/. 1,643
3/. 1,669
4/. 1,657
5/. 1,629
6/. 1,635 spread 45fps Av - 1,651fps
100gr. 3F same as above but with .021" denim patch
1/. 1,627
2/. 1,621
3/. 1,654
4/. 1,656
5/. 1,664 spread 43 Av - 1,644fps - The close numbers and virtually identical speeds show good fit for the thinner .020" denim patch so no need for the thicker one unless further testing shows better accuracy.
110gr. 3F .021" patch as they were already lubed and might as well use them up. Loading was virtually identical to the thinner patch - very easy
1/. 1,720
2/. 1,680
3/. 1,717 spread 40fps - Av. - 1,705fps Only fired 3- sore shoulder note that for all this shooting, I used the thicker 'Magnum' PAST reoil pad on my shoulder yet recoil in this light gun was getting me down. Torn cartilage really stunts testing heavy loads.
Getting 100fps average per 10gr. of powder is pretty good form 80gr. through 100gr., showing this very short barrel was working fine with this granulation and charge weights. At 110gr. of 3F, the average velocity gain dropped to 61 fps. This may have risen to as much as perhaps 75fps had more shots been fired in the 110gr. string, but definitely shows gains are dropping.
A further note that last time testing on the lower range with Taylor, his Virginia rifle, with 44" Rice Barrel in .50 cal, gave only approx. 1,450fps with 80gr. 2F. My short 21" barrel matched that velocity (1,468) with 3F. I'll do a further test using 2F (in a couple weeks) to see if there is an accuracy advantage with 2F in this barrel. I would have liked to achieve 1,650fps for a hunting load, but may have to accept 100fps less. In the field, this will literally make no difference, of course.
