load development

[rohk]

ok, got my 250 ftx grain load, it shoots sub 1" groups. 40 grains for a 2200 fps average.
1" group with the 300 xpb at 35.6 grains for a 1940 fps average.
1" group with 200 ftx at 46.6 grains for a 2579 fps average.
all bullets are moly coated. 16" barrel. powder is lilgun.

Lovin this gun!

Need to find more bullet weights to test.

I have the ability to shot-plate MoS, WS2 and HBN, but it never occurred to me to try it with my 450b. It's interesting to see that you could charge those 200s up to 46.6gr. With non-plated bullets, I got pressure signs at 41gr in my 200 FTX work. That having been said. You can see the velocity for charge weight trade-off that comes from slick bullets. I got something like 2450 fps loading the 200s ahead of 41gr of Lil Gun. IMHO, this caliber with Lil Gun, craves more pressure. Now, it really re-opens my interest in 2400 powder, which worked better with my 200s, but the pressure was too much just as they were getting interesting. I may do some subsequent load testing using coated 200 FTXs and 2400 powder.

Interesting, with my 30-30 it took about 1 grain more powder to bring the speed back up but it also allowed me to go over book max. with no pressure signs.
I look forward to hearing you results with the 200's.
The 200's still show sign's of not enough pressure with some sooting, but the 250's show about the same sooting.

Found the 225's at a real good price so they are next up.

I've tried moly in a number of rifles with mixed success. The only ones which showed significant improvement were .223 loading of the 77 gr SMKs over Varget, and my .270WBY loadings using partitions over RL25, so I still plate those bullets. My .450B uses a straight wall case in a chrome lined bore with a slow twist, shows no accuracy degradation due to fouling and cleans with one or two patches on a jag. I'm not seeing any benefit to be gained from the additional effort and expense? Am I missing something here?

With regard to what I said, I see no need for coated bullets with Lil Gun loads. What I said was trying to reduce pressure using 2400 powder which though a good match for the lighter 200gr FTX, the pressure tends to rise objectionably just about the time the bullet is hitting it's stride. Also, 2400 lights easily at lower temps, even with the mild BR4 primer, which makes it a good choice for up here in MN during deer season. I've seen opening morning temps as low as -13F.

225 grain FTX 43.6 Grains lilgun 2423 fps very good groups

not sure what next 160 gr. barnes TAC-XP maybe?

I've had a hankering for a long time to work up some loads ising the Barnes 200gr XPB, or the 275 XPB, but for the life of me, I can't bring myself to plop down a buck a bullet. I've been checking the General Bullet site for over a year now to see if they'll ever have any of the unbranded XPB's that they say they have, but to no avail. They don't respond to emails either. The listed price on their site is less than Midway, but it's a moot point if they never have any.

Agreed, they are expensive just to punch holes in paper.


Maybe these? http://www.midwayusa.com/viewProduct/de ... ber=342541

For 10 cents a bullet more, you can get the real thing - http://www.midwayusa.com/Search/#bushma ... -4_8-16-32.
